When shopping for shades, the most important thing to look for is the level of UV protection offered by the lens. The safest bet is to buy sunglasses that provide 100% UV protection, or UV 400 protection.

Most expensive sunglasses offer this level of protection on all models, but there is also a wide selection of cheaper sunglasses with adequate UV 400 protection. However, UV protection and lens quality are two different things.

Generally, when you buy a more expensive pair of sunglasses, you will be getting a higher quality lens that will provide a clearer, sharper, more pleasing image with less distortion. See our selection of WileyX sunglasses here or our most recent blog about WileyX here.

What are UV rays?

Sunlight is the main source of UV light, which are high-energy, invisible rays. There are three types of UV light.

UVA rays have the longest wavelengths, followed by UVB, and UVC rays which have the shortest wavelengths. While UVA and UVB rays are transmitted through the atmosphere, all UVC and some UVB rays are absorbed by the earth’s ozone layer.

So, most of the UV rays you come in contact with are UVA with a small amount of UVB. The UV 400 label on sunglasses gives the assurance that the lenses absorb the harmful UVA and B rays up to a wavelength of 400 nanometers.

Here are 9 common myths about sunglasses:

You don’t need sunglasses on a cloudy day False: UV rays are just as potent on a cloudy day as they are on a clear day, and proper eye and skin protection are always needed.

Sunglasses with 100% UV protection are expensive False: You don’t have to pay a premium for proper UV protection. While more expensive sunglasses may offer more stylish frames, higher quality lenses, sharper images, and less glare, it is very easy to find inexpensive glasses that offer 100% UV protection. If you do buy an inexpensive pair of glasses, you might want to have them tested by an optometrist.

Lenses with darker tints are more protective than lenses with a lighter tint False: The tint of the lens has nothing to do with the UV protection of the glasses. A clear lens with no tint and 100% UV protection is better for your eyes than dark, heavily tinted sunglasses without UV protection. In fact, dark lenses without adequate UV protection are actually worse for your eyes than not wearing glasses at all, because the dark tint causes your pupils to become dilated, thus exposing your eyes to more harmful UV light.

You should have UV coating put on your lenses for extra protection False: If your glasses already have UV protection, they do not need to have added protection put on them.

Photochromic lenses don’t block out UV rays as well as regular sunglasses False: As long as they offer 100% UV protection, photochromic lenses provide the same level of UV protection as regular sunglasses.

Polarised, anti-glare lenses are all you need to protect your eyes from UV rays False: While polarised and anti-glare lenses may offer better image clarity, a more comfortable viewing experience, and give you better vision when driving or playing sports, they have nothing to do with UV protection. That being said, most polarised lenses also offer adequate UV protection. Again, if you are in doubt, have your sunglasses checked by an optometrist.

Lens colour is important when it comes to blocking UV rays False: Just like lens tint, lens colour has nothing to do with protecting your eyes from UV rays.

Yellow or amber-tinted “Blue Blocker” lenses offer more protection than regular sunglasses False: While some experts argue that the so-called “Blue Blocker” lenses block additional light waves that are harmful, research has yet to prove this for certain. “Blue Blockers” are currently viewed by most experts as a personal preference choice.

Children don’t need sunglasses as much as adults False: Children often spend even more time in the sun than adults and need proper UV protection just as much. It is also far more common to find cheap children’s sunglasses that do not provide adequate UV protection. Always make sure they have the UV400 label.

Did you know that the eyes themselves are not what actually allow you to see? They are simply a conveyance for messages sent to the brain, via the optic nerve.

Similarly, did you know that only one-sixth of your eye is even visible to the outside world? Or that your eyes are comprised of more than two million intricately connected working parts? And that’s just the beginning! Here are 15 fascinating facts about the eyes.

Healthy vision is important in ensuring quality of life. Two common threats to aging eyes are cataracts and age-related macular degeneration (AMD) which can, however, be prevented to some extend by a good diet.

Some important nutrients are found in common foods, and including them in the daily diet will help to preserve good vision throughout life. Antioxidants protect tissues from the toxic effects of free radicals which lead to a breakdown of cell membranes and nucleic acids.

Free radicals are formed when tissue is exposed to ultraviolet radiation as from direct sunlight, in cigarette smoke, and other air pollutants. The retina is exposed to a lot of light and is therefore a prime spot for free radical damage. This makes it all the more important to provide antioxidants that reduce the high level of oxidative stress.

Specific Nutrients

Vitamin C or ascorbic acid is found in fruits and vegetables, and may reduce the risk of cataracts. AMD may also be slowed if vitamin C and other nutritional factors are taken in combinations. Vitamin C is found in grapefruit, strawberries, Brussels sprouts, ripe papayas, oranges, and green peppers.

Vitamin E or alpha-tocopherol is another powerful antioxidant found in nuts, sweet potatoes, and fortified cereals. It is also found in sunflower seeds, wheat germ oil, and vegetable oils.

Essential fatty acids: These fats are not synthesized in the human body but are required for the proper health and functioning of the nervous system, for energy metabolism and immunity. Among these, omega-3 fatty acids like DHA (docosahexaenoic acid) are vital for retinal function and for the development of vision, being concentrated on the outer parts of the photoreceptor cells. These are anti-inflammatory agents, which helps to prevent AMD. These fatty acids are found in salmon, herring and sardines, as well as tuna, halibut and flounder. Two servings or more a week are advised.

Zinc: This trace mineral is a cofactor in the transport of vitamin A from its storage site in the liver to the retina, where it is converted to melanin. This black pigment is essential in protecting retinal tissues against photodamage. High concentrations of zinc are present in the retina and the choroidal vascular tissue under the retina. Zinc is found in white meats from turkey, oysters, and crab meat, as well as eggs, peanuts, whole grains, and red meats.

Beta carotene which is found in all vegetables and fruits that are deep yellow or orange is part of the essential visual pigments, and its deficiency cases night blindness. Pumpkins, red peppers, carrots, sweet potatoes and winter squash are all prime sources.

Supplements – Do they play a role?

AMD may be prevented or slowed using supplements made to AREDS standards. AREDS stands for the pivotal Age-Related Eye Disease Studies which tested the formula of this mix of antioxidants clinically. The current AREDS 2 version contains more lutein and zeaxanthin than before, which covers any dietary deficiency. Unlike many other supplements, it doesn’t have beta-carotene and is therefore safe for smokers or those who have just quit. In this subgroup, this nutrient could cause a higher risk of lung cancer, though only at very high doses.

While no research suggests exactly how much of each of these nutrients is necessary to keep vision in good working order, the good old rule of five or more servings of colourful fruits and vegetable every day, with fish at least twice a week, seems to be most helpful in preventing eye problems with age.

How to practice good make-up hygiene

There are a number of simple but important steps that can help to prevent eye irritation and eye infections.

• Renew your make-up every three months to reduce the risk of developing infections. This is particularly true in the case of eye make-up like mascaras or eyeliners. In some rare cases, women who have developed an eye infection from cosmetics have been temporarily or permanently blinded, according to the FDA. Some of these infections may stem from the make-up wands or brushes themselves.
• Once a mascara wand or eyeliner brush comes into contact with the eyelashes, contamination of the applicator occurs as eyelashes naturally have bacteria on them. Over time, this contamination of both the brush and the container builds up and can lead to an increased risk of infection or allergic reactions.
• For this reason, sharing cosmetics is not advised at any time, as bacteria can harm another person even if the original user does not experience any reactions or infections themselves.
• Avoid applying make-up at the meeting of the eye and the eyelid to avoid blocking the important Meibomian oil glands, and causing dry eye.
• Fortunately most people won’t experience any problems using make-up for longer than three months. If irritation does occur after using make-up products, it is essential to stop using the product immediately. If the irritation persists, medical attention should be sought.
• Storing make-up products properly is also important. If cosmetics are stored in particularly hot conditions the preservatives in the products are at higher risk of deteriorating.

Risks associated with eye make-up

It is important to remove make-up before sleeping.

Ophthalmologist Dana Robaei published a case study in 2018 about a woman suffering from chronic foreign body sensation in both her eyes. The article detailed the harmful effects that can occur after leaving mascara on overnight.

After examining the eyes, Robaei found subconjunctival mascara deposition beneath both eyelids. This was due to over 25 years of heavy mascara use without taking care to remove it properly. Small pieces of mascara had built up inside the eyelid and formed into solid concretions that were scratching the cornea, resulting in irritation and discomfort.

The patient was left with permanent scarring on the cornea and on the eyelid after a surgical procedure to remove the built up concretions. Although Robaei clarifies it was a rare and extreme case, it nevertheless highlights the importance of removing eye make-up properly every night.

Other reports have been made about the risk of mascara-induced damage to the lacrimal drainage system, with one patient developing a dacryolith (a concretion usually comprising of lipids, epithelial cells and other debris) loaded with mascara.

Other reports in literature reviews on problems caused y mascara include eyelid dermatitis, infection keratitis, and mascaroma, among others.

Additionally, not all make-up applied to the eyes remains within the area of application. For instance, mascara can flake off and small particles travel in the eye, causing redness or irritation. In other cases, the eye can be scratched by make-up brushes or pencils that can then lead to serious eye infections.

Ensuring that any applicator used near the eyes is clean can help to reduce the risk of scratch-induced infections. However, the trauma caused by scratches may still trigger problems or reactions.

Summary

As most make-up and cosmetic products undergo rigorous testing before being sold, the daily use of make-up is thought to pose minimal initial risk.

It is when make-up is not removed properly, contaminated, or used when individual allergies are already apparent, that risks of infection, irritation and permanent damage to the application area increase.

A microbial study asked forty women to use one of two brands of non-waterproof mascara every day for three months. It was found that out of the 33 samples collected from the 40 women, microbial growth was present in over 36% of mascara containers.

As such, the need to practice good make-up hygiene is clear. Careful application of make-up around the eyes can reduce the risk of eye injury and subsequent irritation, infection, and loss of vision, in rare cases.
