How Dangerous Is The Sun To Your Eyes?

There is substantial scientific and medical evidence that the sun has harmful radiation that can cause serious damage to your eyes.  In extreme cases, it can lead to blindness.

This is worse at noon when the UV dose can be 10 times higher than the dose 3 hours earlier or 3 hours later.  Even hats with wide brims can’t protect you from UV rays reflected up from such surfaces as pavement, sand, water and snow.  UV rays can penetrate clouds so the risk can be just as great in the shade.

The list of horrible things that can happen to your eyes, short of blindness, includes, but is not limited to cataracts, pterygium, photokeratitis, photoconjunctivitis (pink eye), and eye cancer.

This problem is compounded by the crazy reality that most people are unaware of this danger, and the people who know and should warn us – Ophthalmologists, Optometrists and sunglass manufacturers, among other, do NOT warn us.

No doctor I have ever been to, including Opthalmologists and Optometrists, have ever told me to wear sunglasses and a wide brimmed hat in the sun to protect my eyes.

It seems that our being unaware of the harmful effects of the sun and, thus, not protecting ourselves adequately, might be as dangerous as the harmful effect of this radiation itself.

(When it comes to the skin, however, the opposite is the case isn’t it?  Who doesn’t apply protective sun screen when going out in the sun? Dermatologists, for sure, deliver this message.)

So, why no warnings about your eyes?

We do not know for sure but have some ideas.

There are no big drug/cosmetic companies who can make big bucks from having you wear sunglasses or a hat with a brim.

The sunglass companies, on the other hand, are mostly into the style, image and design of the sunglass, factors which generate sales. The protective benefits from lenses get some, but not a lot of attention. Same for the hat companies.

When was the last time you chose a sunglass mostly because of the protective qualities of the lens?

A word about contact lenses: Not all contact lenses offer UV protection and in fact, most do not.  One exception is Acuvue brand. Nevertheless, no matter the brand, when wearing contact lenses, wear sunglasses too.

Pau Rio is telling you now – for many reasons – wear sunglasses in daylight, all year long.  Yes, even in the shade!

Not only are our eyes vulnerable to dangerous medical conditions for prolonged unprotected exposure to the harmful radiation of the sun, but the effect starts in early childhood and accumulates for the rest of our lives.

It is too late to turn back the clock, but not too late to start now.
