How do sunglasses protect your eyes

Getting your daily dosage of Vitamin D in moderation will do your body a lot of good, but if you exceed the limit, your body could be affected. Sunlight contains visible light, ultraviolet (UV) light, and infrared (IR) light, which cannot be seen by the naked eye. Too much exposure to this light is associated with damage to the eye. While you may enjoy the sunny days on the beach, sipping on your favourite drink or are out for near-exhausting site work, exposure to sunlight will not only harm your skin but your eyes too!

Common dangers linked with exposure to sunlight: –

  • Sunburn

Yes, you have read it right. Exposure to sunlight can cause sunburn on your eyes that result in inflammation of the cornea. The cornea is the clear outer layer at the front of the eye. The cornea functions to protect the inner parts of the eye. It contributes to the reflective power of the eye. If your eyes get sunburnt, your eyes may be itchy, watery, and sensitive to light. These sunburn effects usually aren’t serious, and they fade away automatically after a few days. If it causes you too much discomfort, then apply a cold compress to it. But best to wear sunglasses to prevent this.

  • Cataracts

The inner region of our eyes comprises a natural lens which refracts the light that enters, enabling us to see. A cataract leads to cloudy vision. In layman’s terms, it may make your vision foggy. To rectify the cataract, you have to seek medical advice immediately.

  • Macular Degeneration

It’s a disease that causes loss of vision. The macula is the back region of the retina that is responsible for central vision. This usually happens due to old age, but certain studies state that exposure to UV lights can increase the risk of macular degeneration.

How can you prevent your eyes from this damage?

The answer to this question is very simple. Just wear your favourite pair of coolers before you head out for the day. Sunglasses protect your eyes from harmful ultraviolet rays. You should always wear good sunglasses to block these harmful lights. Your sunglasses are good if they contain any one of these elements.

  • UV Coating

Applying UV coating to the plastic lens helps in blocking off harmful UV rays. Polycarbonate glasses have in-built UV protection, so you just have to consult with the eyewear expert or ophthalmologist about which glasses would suit you the best.

  • Mirror Coating

It helps in filtering the harmful light from your eyes and aids in reducing eye strain.

  • Anti-Reflective Coating

These specific coated lenses help to filter the amount of reflective light in the lens. These coatings are either applied on the front, back, or both sides to give the best results.

It is a fact that our eyes need protection from harmful ultraviolet rays, glare, and reflection, especially when it comes to water sports, sports, and just to protect our eyes from the harmful rays of the sun. But using the right shades and lenses is also important to protect our eyes from any kind of damage, so it is essential that we use the right shades and lenses.
