Why Do Onions Make Us Cry?

Onions are one of the most common staple foods around the globe. Ironically, for a vegetable so delicious, they can often be tear-jerkers.

Read on to learn why onions cause your eyes to tear and sting, and what you can do to minimize discomfort.

Why Does Cutting Onions Cause Tearing?

Onions produce a sulfur compound called propyl sulfoxide that is stored in the cells of the onion bulb (the part of the onion we eat). Onions grow underground, where they can be eaten by all types of creatures. This odorous sulfuric compound acts as a deterrent to small animals with big appetites.

When one slices into an onion and breaks open its cells, the sulfur compound is released and mixes with the moisture in the air — turning it into smelly and irritating sulfuric acid. When this chemical rises up and comes in contact with your eyes, it stings!

To keep your eyes from potentially being damaged from this chemical exposure, your brain triggers your eyes to tear and flush out the irritating gas particles. Once enough tears have flushed out the sulfuric acids particles from the eye, clear vision and comfort is usually restored. Although your eyes may sting and feel unpleasant, symptoms are temporary and the sulfuric acid won’t damage your eyes.

How Can I Reduce Eye Discomfort When Chopping Onions?

Most experienced chefs will tell you that chilling your onions in the fridge for at least 30 minutes before slicing them will reduce the amount of tearing they cause. Propyl sulfoxide escapes slower in cooler temperatures, reducing the amount of sulfuric acid in the air.

You can also try cutting the onions at arm’s length, or direct the odorous air away with a small fan. Some say that chopping onions immersed in water also helps. Another option is to wear kitchen goggles to protect your eyes.

Furthermore, try to use fresh onions whenever possible. The longer an onion has been stored, the more likely it will induce tearing and discomfort. Try to avoid slicing near the root end of the bulb, as that area has the highest concentration of sulfuric compounds.

Pink Eye? It Could Be Coronavirus

How to prevent conjunctivitis and protect your eyes

When you have a virus, especially one that causes a hacking cough, runny nose, and other symptoms of a common cold or flu, it’s typical for your eyes to also get puffy and red. You may be suffering from viral conjunctivitis, also known as pink eye.

How do viruses get into your eyes?

It’s rather simple. When you’re sick, you can easily transfer viruses to your eyes by sneezing, coughing into your hands, or blowing your nose – and then touching the area around your eye.

The coronavirus – pink eye connection

According to the American Academy of Ophthalmology (AAO), doctors have discovered that COVID-19 can cause conjunctivitis. If you’re standing within six feet of an infected person, and they cough or sneeze, the virus can enter your eye. Alternatively, if someone sneezes and virus particles land on the shopping cart that you take and push around a store, and then you touch your eyes without washing your hands first – you’re giving the virus direct access.

However, despite the apparent ease with which coronavirus can infect eyes, the AAO reports that only about 1 – 3% of all patients with the virus contract pink eye.

Preventing pink eye

Like always, prevention is the most effective medicine! Eye care professionals recommend following these tips to help prevent getting viral conjunctivitis:

  • Wash your hands correctly

The CDC instructs people to wash their hands in accordance with these steps: wet your hands, turn off the tap, apply soap, lather and scrub for 20 seconds, turn on tap and rinse. Air dry your hands, use a disposable paper towel and discard it immediately, or use a clean (not shared) towel.

  • Keep your fingers away from your face

No rubbing or wiping your eyes! Even if you don’t feel any symptoms of coronavirus, it’s essential not to touch any part of your face. To wipe away tears or remove makeup, use a clean tissue.

  • Don’t share your personal things

As generous as you may feel about letting others use your personal items, now’s the time to keep things to yourself. For example, the CDC recommends not sharing eye drops, makeup, makeup brushes, contact lenses cases, pillowcases, or towels. Pink eye is highly contagious.

  • Consider wearing glasses instead of contacts

While there’s currently no evidence to prove that wearing contacts raises your risks of contracting the novel coronavirus, there’s some evidence that shows you can get Covid-19 by touching a contaminated surface and then touching your eyes. In general, contact lenses wearers touch their eyes more often than people who wear eyeglasses, so it may be smart to make a temporary switch from contact lenses to glasses. However, this is only a friendly recommendation and not a hard-and-fast rule. If you prefer to stick with wearing contacts, washing your hands thoroughly can help keep you and your eyes safe.

Treatment for conjunctivitis

Regardless of whether your pink eye is caused by coronavirus or a different virus, there is no treatment for viral conjunctivitis. Usually, it goes away on its own within one to two weeks.

To alleviate your painful symptoms, eye doctors recommend:

  • Taking an over-the-counter pain medication, such as acetaminophen, ibuprofen or any anti-inflammatory drug
  • Applying a warm compress on your eye for a few minutes; take care to use a clean wash cloth each time and for each eye
  • Use artificial tears (lubricating eye drops) to soothe your eye irritation; don’t touch the bottle tip to your eye

Are you sick and have pink eye symptoms?

Now is not the time to make a DIY diagnosis. Eye redness, even if you have a virus, doesn’t necessarily indicate that you have conjunctivitis. A wide range of other conditions can lead to the same symptoms. Contact an eye doctor near you for help to figure out what’s causing your eye pain. Don’t visit your eye care practice without calling for guidance first, because extra precautions must be taken with patients who may have COVID-19.

Eye Make-up VS. Your Eyes

Dream Big

It is almost every little girl’s dream to start playing with make-up. From eyeliner and mascara to eyeshadow and lipstick. About 65% of women wear eye make-up. Personally, I cannot go a day without my mascara, but I always make sure that I have proper eyelid hygiene to prevent any harm to my ocular surface. As time goes on technology only gets better and now inventions are created every day to make our day to day a little easier.

A new beauty technique that is very popular is eyelash extensions. Now anyone can have long, dark eyelashes but sometimes it is not always as glamorous. Eyelashes are not just there for beauty, their main function is to protect our eyes from harmful particles like dust, sand or debris from the environment.

What’s Up With Eyelash Extensions?

When eyelash extensions are placed, they tend to block the meibomian glands. These glands are important openings along the eyelids for the oil glands to exert protective oils to the tear film. When meibomian glands are blocked, it causes a risk increase for dry eye. Our eyelashes are a certain length for a reason, and that reason is for protection. Improper installation of eyelashes can cause severe eye infections.

False eyelashes are not the only item to be cautious about. Eye make up such as mascara, eyeliner and eyeshadow can also cause risk to the ocular exterior. A tip I would recommend to you, avoid wearing any eye makeup the day of your annual eye exam. Make-up products such as eyeliner, mascara, and eyeshadow can hide or even imitate blepharitis. Blepharitis is defined as eyelid inflammation caused when the small oil glands of the inner eyelid become agitated. Symptoms of blepharitis include red, itchy eyelids that may look greasy and crusted. If a patient is wearing eye shadow or eyeliner the optometrist is not able to give the patient a proper exam because remember, an eye exam is not just about having your vision checked. The optometrist is also responsible for checking the health of the eyes inside and out.

Makeup and Your Eyes

Even mascara should not be worn to your annual eye exam. When mascara is applied to eyelashes, there is a thick, dark coat covering the eyelash. With the eyelashes covered, this prevents the doctor from seeing signs of Demodex. Demodex are compact mites that reside in or around hair follicles. They are most commonly known as eyelash mites. These mites are usually harmless but when there is an abnormal amount of eyelash mites, symptoms can involve itchiness, redness, burning or rough patches around the eyes. To contact lens wearers, be extra cautious to mascara flaking off. The pieces of mascara can enter the tear film and cause irritation. The flakes of mascara can even embellish under the contact lens and cause corneal erosion or even starch the ocular surface of your eyes. If the ocular surface is scratched bad enough, some patients are not able to wear contact lenses again.

It is important to take proper care of your eyes. After all you only have one set of eyes. Most women have their basic makeup routine every morning, but most women do not have an eyelid care routine. It is important to take off any eye make-up before bed to prevent any irritation or infections to the eyes. I use Blephadex eyelid wipes every night before I go to bed, they are made with coconut and tea tree oil to help cleanse, moisturize and refresh my eyelids.
