Phosphene from rubbing the closed eyes where first described at least since Ancient Greece, but I caught myself thinking that I wouldn't want to try it out. So I wonder, how safe it is to actually rub closed eyes or put pressure on the human eye in general? Can frequent but small, or rare but sharp, application of pressure cause myopia or other eye disorders? What is the maximum pressure before the eye is damaged? What happens with the eye if you accidentally hit it?

I remember several times during my childhood accidentally poking myself in the eye with a finger-the experience was very uncomfortable, I couldn't even open the eye for several minutes, but I don't think anything happened to my eyes since then, and my myopia was probably caused by any other factor than pressure damage.


The answer is both yes and no, depending on how often and how hard one rubs his or her own eyes.

Occasional light rubbing is not a problem-- it stimulates tear production and relieves stress by lowering heart rate via the oculocardiac reflex.

Frequent hard rubbing is a problem-- it can worsen eyesight in people who already have progressive myopia, and worst-case-scenario lead to retinal detachment. For those with glaucoma, can interrupt blood flow and even cause nerve damage. It can (but rarely) scratch, tear, or deform the cornea leading to pain and distorted vision. It can lead to damage of small delicate vessels, causing a subconjunctival hemorrhage, which is benign despite its worrisome appearance.

It is generally recommended to just avoiding rubbing the eyes altogether!

Some sick bird symptoms

If your bird is sick or injured please take it to an AVIAN VET don't email me!!

If you get a new bird, always take it to your vet ASAP for a thorough exam and medical advice!!

And remember, birds often pretend to be fine when someone is watching nearby (survival instinct), so observe very carefully.

  • Puffed-up feathers. Birds fluff up their feathers to keep warm, and also when they relax for sleep . and also when sick. A bird who sits puffed up much of the day is likely in trouble.
  • Tail-bobbing when breathing. Birds who sit there puffed up, bobbing their tails, may be sick.
  • Not eating their favorite food. Maybe the bird's full -- but they need to eat often, so if after a day the favorite food is untouched, something's likely wrong.
  • Half-closed or closed eye(s) for much of the time. Alert and healthy birds usually have both eyes wide open while awake. If the eyes start closing, and it's not because you're scratching a birdie head and inducing pure birdie joy, the bird might be sick. Oh, and be careful: birds often close one eye but not the other. You may not notice a bird is keeping its farther eye closed sometimes.
  • Sleeping excessively. Like people, birds who sleep a lot more than usual may be in trouble.
  • Bad posture when at rest. Healthy small parrots usually sit somewhat vertically, not fully horizontally, though it depends on the type. Bad posture from sickness is usually combined with puffed up feathers.
  • Discharge/wetness around the nose. It may be hard to see the nose, but it's usually at the top of the widest part of the bill, right near or under the feather line. Watch for moisture/discharge there. An occasional sneeze is OK, but if it stays moist.
  • Throwing up/getting undigested or half-digested food stuck to the cage in weird places. Can be mistaken for harmless courtship-related regurgitation. New owners should play it safe and check with a vet. You can eventually learn to tell if it's nausea vs. lovey-dovey behavior, but watch very carefully.
  • Poop sticking to the vent feathers. This is apparently a common sign of possible sickness, especially if it keeps happening.
  • Discolored, undigested, or runny poop. Watch for changes in the shape/color of the poop. Runny poop can happen if you've just given your bird a bath or if it just drank lots of water, but those effects only last for about an hour with small birds. Color changes can mean a change in diet (seed diets usually produce greenish poop, pellets usually produce brown), but off-colors or unusual colors are a warning sign (black is usually a bad sign). The poop should also look well-digested -- no lumps in it that can be identified as what they used to be. If your bird eats seeds, there should NOT be whole, undigested seeds in the poop -- that's a sign of dreaded PDD.
  • Ragged, poorly preened feathers. A sign the bird isn't feeling up to caring for its feathers, which is a bad sign, since feathers are vital to a bird's survival in the wild.
  • Sneezing. Especially if it's frequent.
  • Lack of energy. If a normally playful bird doesn't play very much any more, it may well be sick.
  • Sudden temperament change. A normally mellow bird may get grouchy and nippy, or a rambunctious bird might just get very quiet and mellow. It might be just hormones or a bad feather day . or it could be something else.
  • Weight loss. Dangerous especially to small birds, who don't have much in the way of bodily reserves. Most casual bird owners don't weigh their birds very often, so it's important to work with a vet to check a bird's weight. Sometimes you can tell by feeling the keel bone, the bone that runs down the center of the bird's chest -- if it sticks out like a razor, the bird is starving! In a healthy bird, there's so much flesh on the chest you can hardly feel the bone.
  • Crooked beak/crooked toenails. Either can be a sign of long-term illness, and should be checked out by your vet as soon as possible.
  • In budgies, crusted-over nose (cere) and/or feet. A possible sign of mites. Talk to your vet about the options.
  • Dull feathers/feathers with unnatural banding. Many possible sicknesses here! With cockatoos and cockatiels, also watch for a lack of "powder" (though young birds don't seem to have as much of it). If the bird's appearance is gradually getting worse, see a vet!
  • Plucked feathers. I've heard this is often due to parasites or other problems, not just boredom. Get a full battery of tests. This site has more information.
  • Any sign of blood! Bad sign. If your birdie is bleeding, you need to stop it immediately. Call your vet if you're not sure how. If it's a broken pin feather that's bleeding, apparently it needs to be pulled out with pliers! For other cases, you need Quik-stop or other styptic (bleeding-stopping) powder (cornstarch can work too) -- GET SOME just in case. Example of using cornstarch: One time one budgie of ours had a toenail clipped too short at a vet exam, and it started bleeding heavily at home. It's alarming to see big drops of blood falling from a tiny bird!! (Note: wounds are not always conveniently visible.) Styptic stick didn't work. We grabbed the budgie (carefully, in a small towel) and inserted the bleeding toenail into a small glass container of cornstarch, packed the cornstarch against the wound, and held it there for 20 minutes (of course making sure the bird could breathe freely while we held it). That finally got the toe to stop bleeding, but we watched carefully for some time to be sure.

Finally, sometimes the worst happens, despite the best care and the best vets. Birds can and do die. Sometimes it's from careless breeding, sometimes it's pure bad luck, or an accident, or maybe it's just time for the bird to pass on. The best you can do is to get as informed and educated as possible (from more than one source), get to know your bird's individual quirks . and to remember that keeping your pet happy, well-loved, and mentally occupied is one of the best preventative medicines ever!


This Is the Only Way You Can Get COVID From Surfaces, Doctor Warns

In the fight to control our current pandemic, scientists have been heavily researching COVID-19 for months to better understand exactly how the virus spreads. Discoveries made since the beginning of the pandemic have helped change public health guidelines, shifting from a primary focus on sanitizing surfaces in the early days to now avoiding poorly ventilated and crowded areas (because of what we know about aerosolization). In fact, doctors now say the only way to catch COVID from surfaces is the unlikely scenario of touching an item teeming with the virus and then touching your mouth, eyes, or nose.

During a live YouTube Q&A from the Association of American Medical Colleges (AAMC) on Aug. 18, two doctors—Atul Grover, MD, PhD, executive director of the AAMC Research and Action Institute, and AAMC Chief Scientific Officer Ross McKinney, Jr., MD—discussed just how likely you are to contract COVID through touching objects.

"The risk of virus spread by contact with items—which are called fomites—is really pretty small," McKinney, Jr. said. "What has to happen is you have to have a significant amount of virus on whatever that thing is." And you have to do more than just touch that virus-laden object because COVID "doesn't go through your skin," the doctor said. "You have to transfer it from wherever you touch it, from that to your nose, mouth, or eyes for you to become infected. So, it's unlikely."

McKinney's assessment echos the same message that the Centers for Disease Control and Prevention (CDC) has held since it changed its guidelines in late May. While the agency maintains that you can contract the virus through touch, its website states that it's "not thought to be the main way the virus spreads." Since then, the CDC has continued to warn the public that the virus is most commonly transmitted through droplets that are released into the air when an infected person coughs, talks, sneezes, or sings.

But other health experts reiterate that it's important not to forget that even though the risk is low, it it still possible to get COVID from objects. "High touch surfaces like railings and doorknobs, elevator buttons are not the primary driver of the infection in the United States," comparative immunologist Erin Bromage, PhD, a biology professor at the University of Massachusetts, Dartmouth told The New York Times in May. "But it's still a bad idea to touch your face. If someone who is infectious coughs on their hand and shakes your hand and you rub your eyes—yes, you're infected. Someone's drinking from a glass, and you pick it up near the rim and later rub your eyes or mouth, you're infected."

Despite it being very unlikely to catch COVID from surfaces, doctors still believe that the full combination of the CDC's recommended health guidelines make for the most effective protection routine. "If you're washing your hands, maintaining that distance, and wearing a mask, you're in pretty good shape," Grover said in the AAMC Q&A above. "Even if you're touching these fomites, there's no way for it to get into your system through intact skin on your hands."

Then, he joked: "[Just] don't go out and lick your mail." And for more risk factors to avoid, check out 24 Things You're Doing Every Day That Put You at COVID Risk.


What uses does rubbing alcohol have?

Rubbing alcohol is a common household chemical. It has several potential uses in personal care, as well as in general household cleaning.

However, the incorrect use of rubbing alcohol can cause serious side effects, including skin irritation and poisoning.

In this article, we list some common uses for rubbing alcohol. We also outline some situations in which a person should avoid using this chemical.

Common uses for rubbing alcohol include:

Share on Pinterest People can use rubbing alcohol after removing a tick from the skin.

People can use tweezers to remove a tick carefully from the skin. Following its removal, they can use rubbing alcohol to disinfect the bite. They should apply rubbing alcohol to a cotton swab and dab it onto the area where the tick had attached itself.

According to the American Academy of Dermatology (AAD), people can use rubbing alcohol to help clean the skin around new ear piercings. To do this, a person should dip a cotton ball or pad into the rubbing alcohol. They should then gently wipe it around the piercing on the front and back of the ear.

People should clean the piercing twice a day to help prevent bacterial infections and scabbing.

It is important to note that some experts disagree with this advice, recommending that people avoid using rubbing alcohol because it might slow the healing process.

Rubbing alcohol can help kill odor-causing bacteria. A person can apply rubbing alcohol under the armpits to help eliminate body odors.

However, they should avoid applying rubbing alcohol soon after shaving, as this will cause stinging.

Shoes can develop a strong odor, particularly if a person wears them while exercising or doing other physical activity. Spraying the insoles of the shoes with rubbing alcohol can help eliminate odor-causing bacteria.

A person should fill a spray bottle with rubbing alcohol and use this to spray the insides of the shoes. Leaving the shoes in the sun will help dry them out.

It is possible to make a room deodorizer by pouring rubbing alcohol into a spray bottle and adding a few drops of an essential oil. A person can then spray the mixture around the room to help mask unpleasant odors.

By mixing water and rubbing alcohol, a person can create a reusable and malleable homemade ice pack. They can follow these steps:

  • Fill a sealable freezer bag with 2 cups of water and 1 cup of 70% rubbing alcohol.
  • Push as much air out as possible, and seal the bag.
  • Place the filled bag inside another freezer bag, pushing out as much air as possible before sealing it.
  • Freeze for several hours.

Once the ice pack is ready, people can apply it to sore muscles or joints to relieve pain and inflammation.

Rubbing alcohol can help clean and disinfect hard surfaces. It is effective against most, but not all, pathogens.

The main ingredient in rubbing alcohol is isopropyl alcohol (IA). Most rubbing alcohols contain about 70% IA, but the amount can range from 60% to 99%, depending on the product.

According to the Centers for Disease Control and Prevention (CDC) , alcohol solutions are most effective at concentrations of 60–90%. People should avoid using diluted solutions that have a concentration of 50% or below, as these will be less effective in killing pathogens.

Rubbing alcohol can also help disinfect household items, such as bathroom or kitchen sponges or cleaning cloths.

A person should pour some rubbing alcohol onto the sponge or cloth and let it soak for several minutes or hours inside a sealable container.

Alcohol evaporates quickly and can kill pathogens on phones, laptops, tablets, and other devices. It is best to use a rubbing alcohol with 99% IA for electronics.

A person should apply a small amount of the rubbing alcohol to a paper towel or cloth and gently wipe it across the electronic device.

This chemical can also help remove water from an electronic device if a person accidentally drops it into water or spills some water on it. If the device was switched off at the time, removing water with the rubbing alcohol should recover it.

Jewelry can collect a lot of grime and bacteria through frequent wearing. Cleaning the jewelry with rubbing alcohol will make it more hygienic to wear.

People should apply the rubbing alcohol to a soft cloth or cotton swab. They can then rub this against the jewelry to help remove surface dirt and bacteria.

A 2018 review investigated the use of different aromatherapy ingredients for the treatment of nausea and vomiting following surgery. Rubbing alcohol was one of several aromatherapy ingredients that the researchers tested.

They found that inhaling rubbing alcohol vapor rapidly alleviated nausea and reduced the need for antinausea drugs following surgery. However, they noted that the studies that the review included were of low-to-medium quality. As such, further studies are necessary to confirm the findings.

A person should talk to their doctor before inhaling rubbing alcohol vapor to alleviate nausea. Inhaling too much vapor can cause serious side effects in both children and adults.

A person should not use rubbing alcohol for the following purposes:

1. Bathing

People should avoid adding rubbing alcohol to their bathwater. Prolonged exposure to rubbing alcohol can cause the skin to absorb the alcohol, which can lead to toxicity in both children and adults.

2. Reducing a fever

Rubbing alcohol can create a cooling sensation on the skin, but it will not lower a person’s core body temperature. As such, it is not an effective treatment for fever.

In fact, inhaling large quantities of rubbing alcohol can lead to additional health problems, such as:

3. Treating acne

Rubbing alcohol causes drying of the skin. According to the AAD, dry skin can make acne appear worse. It can also increase the frequency and severity of acne breakouts. People should, therefore, avoid using rubbing alcohol as a treatment for acne.

Anyone who is concerned about acne should speak to a doctor or dermatologist for advice on effective acne treatments.

4. Treating lice

A person should not use rubbing alcohol to treat lice. Rubbing alcohol can kill lice, but it can also cause adverse reactions on the scalp.

A person who has lice can ask their doctor or pharmacist for advice on effective lice treatments.

5. Sterilizing medical and surgical equipment

According to the CDC, rubbing alcohol is not suitable for sterilizing medical and surgical equipment because it does not effectively kill bacterial spores.

A bacterial spore is a protective layer that forms around the DNA of certain bacteria. It allows the bacteria to lie dormant until environmental conditions become more favorable for their growth.

6. Internal use

According to the National Capital Poison Center, drinking a small amount of rubbing alcohol typically causes few symptoms. However, drinking a significant amount can cause poisoning and serious illness.

Some potential effects of drinking rubbing alcohol include:

  • sedation
  • slurred speech
  • unsteadiness when walking
  • vomiting
  • bleeding in the stomach and intestines

If an adult or child accidentally swallows rubbing alcohol, they or their caregiver should contact Poison Control immediately on 800-222-1222. If symptoms are present, a person should phone 911 for emergency medical treatment.

Rubbing alcohol has several potential uses for personal care and household cleaning. These uses include cleaning bites and piercings, eliminating odors, and cleaning and disinfecting surfaces and items within the home.

People should avoid inhaling large quantities of rubbing alcohol vapor, as this can have serious side effects. They should also avoid long-term use of rubbing alcohol on the skin.

Drinking rubbing alcohol can cause poisoning and serious illness. A person should phone a poison control center or 911 immediately if they or their child accidentally swallows rubbing alcohol.


Latest Updates

An outbreak associated with a shopping mall in Wenzhou, China, may have been fueled by fomite transmission. In January, seven workers who shared an office in a shopping mall became ill when one of their co-workers returned from Wuhan. The mall was closed, and public health officials tracked two dozen more sick people, including several women who had shopped at the mall, as well as their friends. None of them had come into contact with the original sick office workers. The researchers speculated that a women’s restroom or the mall elevators had been the source of transmission.

Other studies have used invisible fluorescent tracers — fake germs that glow under black light — to track how germs are spread from surfaces. The findings are unnerving. In one series of experiments, 86 percent of workers were contaminated when spray or powder tracers were put on commonly touched objects in an office. When tracer powder was put on a bathroom faucet and exit doorknob, the glowing residue was found on employees’ hands, faces, phones and hair. From a shared phone, the tracer spread to desktop surfaces, drinking cups, keyboards, pens and doorknobs. A contaminated copy machine button added a trail of fluorescent finger prints transferred to documents and computer equipment. And just 20 minutes after arriving home from the office, the fake germs were found on backpacks, keys and purses, and on home doorknobs, light switches, countertops and kitchen appliances.

A video making rounds on the internet shows how the black light experiment works. The glow germs are put on the hands of just one diner at a buffet, but by the end of the meal, everyone at the table has come into contact with the glowing germs. The video explains why scientists discourage the sharing of food during a viral outbreak.

But while those experiments show how germs can spread on surfaces, the microbe still has to survive long enough and in a large enough dose to make you sick. Eugene M. Chudnovsky, a professor at the City University of New York, notes that surfaces are not a particularly effective means of viral transmission. With the flu, for instance, it takes millions of copies of the influenza virus to infect a person through surface-to-hand-to-nose contact, but it may take only a few thousand copies to infect a person when the flu virus goes from the air directly into the lungs.

Dr. Chudnovsky, a theoretical physicist whose research has focused on the spread of the airborne infection, said a similar pattern is likely to be true for the new coronavirus, but the exact numbers are not known.

“I believe the C.D.C. is right when it says that surface transmission is not a dominant one,” said Dr. Chudnovsky. “Surfaces frequently touched by a large number of people, like door handles, elevator buttons, etc., may play a more significant role in spreading the infection than objects touched incidentally, like food packages delivered to homes.”

The bottom line is that the best way to protect ourselves from coronavirus — whether it’s surface transmission or close human contact — is still social distancing, washing our hands, not touching our faces and wearing masks.

“Hand washing is important not only for fomite transmission, but also for person-to-person transmission,” said Dr. Daniel Winetsky, a postdoctoral fellow in the division of infectious diseases at Columbia University. “The respiratory droplets we produce when speaking, coughing and sneezing fall mostly onto our hands, and can fall onto other people’s hands if they are within six feet from us.”


Applying the eyedrops (a nurse will show you how to do this before you go home)

  • Look in a mirror, if necessary a magnifying mirror such as a shaving or make-up mirror.
  • Pull the lower eyelid down to form a pocket.
  • Place one drop into the pocket formed. If you are not sure that the drop has gone in, instil another as it is important to be sure that you have had the medication and you will
    not come to any harm from an extra drop.
  • You may find it helpful to rest your hand on your nose to steady it.
  • Close the eye for about one minute to help absorption.

You may prefer to ask someone else to instil the eyedrops. It does not matter if you accidentally touch your eye with the tip of the bottle, but obviously you must take care not to poke the eye hard.

If you use eyedrops for other reasons eg: glaucoma, you must continue these as normal. Wait about 3 minutes between the different types of eyedrops. It does not matter in what order they are applied.


When you close your eyes and press on them with your fingers, why do you see weird patterns/designs?

I close my eyes and press on them with my fingers, after about 3 seconds I start to see weird moving patterns, like an optical illusion. Like http://img.gawkerassets.com/img/18dn0kik4y440jpg/ku-xlarge.jpg that but actually moving.

The photoreceptors in your eyes, in addition to regular light, are triggered by, though less sensitive to, pressure. The effect you see is your photoreceptive cells being stimulated, despite no light being present.

thanks! i used to think it was a super weird thing only I could do

I see these patterns anytime I close my eyes, without pushing on them. What causes that?

So is this why you see stars after taking a big hit? because the shock of the blow caused pressure changes in your eyes?

any explanation on why it would evolve to detect pressure? Like would it help mountainous people with less air-pressure?

Would you or others know: Do blind people sense this pressure/see the patterns?

This also explains why children born blind often have "sunken" eyes. They push on them to create visual stimulation. The drive is that strong.

Is it harmful at all? Like how they say it's bad to rub your eyes?

Children who are almost blind do this instinctually: it is called the oculodigital reflex. They press on their eyes to simulate the pathways for vision somewhat. It is unfortunately a poor prognostic indicator for future sight.


What is isopropyl alcohol?

Isopropyl alcohol kills or prevents the growth of bacteria on the skin.

Isopropyl alcohol topical (for use on skin) is used to help prevent bacterial skin infections from minor cuts or scrapes. Isopropyl alcohol is used in healthcare settings to prevent infection that may be caused by needle punctures.

Isopropyl alcohol is also used as a topical rub to help relieve minor muscle pain.

Isopropyl alcohol may also be used for purposes not listed in this medication guide.


Why Is Vaseline Good for Your Eyes?

Vaseline Petroleum Jelly has been the most admired and widely used jelly over a century. It’s a low-cost method to repair, heal and moisturize dry, chapped skin. Apart from relieving skin dryness, this “marvel jelly” has numerous appeal uses that you may not be understanding. Let’s have a look at the benefits of baseline for eye health.

Does Vaseline Help Bags Under Eyes?

Yes, it is true that vaseline will help you minimize the eye bags under the eyes. The vaseline has the very stable chemical role. After you eat it, it’s not absorbed and absorbed. It has no damage to human. Its main characters are colorless, unappetizing, transparent, jelly kind liquid and non-toxic. The oral has a sweet taste which liquifies in water. It can make the skin keep wetness. The intravenous injection can minimize high blood pressure and cranial pressure, entering the intestinal tract which can defecation.

Hence, the eye bags under eyes will be released because of the good blood circulation of blood and good stomach. In the properties, vaseline has extremely water repellency which is challenging to be blended with water. As previously pointed out, vaseline is undoubtedly an excellent hydrating supplies and the taste of it is really weak. It can be used for basic skin product to include the fragrance. If you have the allergic character at alcohol, you have the facial skin and the climate is dry, you might use the vaseline, too. Sometimes, the vaseline could also stop the bleeding.

Does Vaseline Help Dry Eyes?

Petroleum jelly can make wrinkles less apparent because it’s adding moisture to the skin, which softens lines, but it can’t actually prevent aging. (CNN)

Well, yes, Vaseline can help to treat dry eyes. Inning accordance with some experts, Vaseline includes vitamin E and C, so by utilizing it in a long time, it can just do an assistance to your dry eyes. Besides, when you suffer dry eyes, you have to drink more water and have some eye drops to treat your symptoms. And dry eyes can be triggered by eye irritants, so you must not touch your eyes with your dirty hands. Just wear eye spot to safeguard your eyes.
