Sunglasses are more than just a fashion statement - they’re important protection from the hazards of UV light.

If you wear are sunglasses mostly for fashion that’s great, just make sure the lenses block UVA and UVB rays.

And if you don’t wear sunglasses, it’s time to start.

Here are your top 6 reasons for wearing sunglasses:

Preventing Skin Cancer

The strongest evidence that sunglasses provide a medical benefit is in preventing skin cancer on your eyelids. UV light exposure from the sun is one of the strongest risk factors for the development of skin cancers.  

Each year there are more new cases of skin cancer than the combined incidence of cancers of the breast, prostate, lung and colon.

About 90 percent of non-melanoma skin cancers are associated with exposure to ultraviolet (UV) radiation from the sun.

Your eyelids, especially the lower eyelids, are also susceptible to UV light and they do develop skin cancers somewhat frequently.

Many people who now regularly apply sunscreen to help protect them from UV light often don’t get that sunscreen up to the edge of their eyelids because they know the sunscreen is going to make their eyes sting and burn. Unfortunately, that leaves the eyelids unprotected. You can fix that by wearing sunglasses that block both UVA and UVB rays.

Decreasing Risk For Eye Disease

There is mounting evidence that lifetime exposure to UV light without protection can increase your risk of cataracts and macular degeneration. It also increases your risk of getting growths on the surface of your eye called Pinguecula and Pterygiums.  Besides looking unsightly they can interfere with your vision and require surgery to remove them. All of those problems are better off with prevention than treatment.

Preventing Snow Blindness

The snow reflects UV light and the exposure can be intense enough on a sunny day to cause a burn on your cornea like what happens when people are exposed to a bright welding arc.

Protection From Wind, Dust, Sand

Many times, when you are spending time outdoors and it is windy, you risk particles blowing in the wind getting into your eyes. Sunglasses help protect you from that exposure. The wind itself can also make your tears evaporate more quickly and cause the surface of your eye to dry and become irritated and then cause the eye to tear again.

Decreasing Headaches

People can get headaches if they are very light sensitive and don’t protect their eyes from bright sunlight. You can also bring on a muscle tension headache if you are constantly squinting because the sunlight is too bright.

Clearer Vision When Driving

We have all experienced an episode of driving, coming around a turn and going directly into the direction of the setting or rising sun that causes our vision to be significantly impaired. Having sunglasses on whenever you are driving in sunlight helps prevent those instances. Just a general reduction in the glare and reflections that sunlight causes will make you a better and more comfortable driver.

So it’s time to go out there and find yourself a good pair of sunglasses that you look great in, and that protect your health too.

Your eye-care professional can help recommend sunglasses that are right for your needs.

A recent study published in JAMA Ophthalmology has demonstrated in older women a correlation between having cataract surgery and a decrease in death rate from all causes.

The data comes from a prospective longitudinal study called the Women’s Health Initiative. This study involved women 65 years or older and collected data from Jan. 1, 1993, until Dec. 31, 2015.

In the study, there were 74,044 women who had been identified with a cataract and within that group 41,735 had undergone cataract surgery during the study time period.

The results showed that of those in the group who had cataract surgery, the mortality - or death - rate was 1.52 deaths per 100 person years. That means that in any given year if you took 100 women who had cataract surgery about 1.52 died in that year. The mortality rate in the women who did not have cataract surgery was 2.56 deaths per 100 person years. Those numbers mean that women who had cataract surgery were 40% LESS LIKELY to die in any given year than women who did not have surgery.

An important aspect of this study is that the authors accounted for several reasons that might have increased the death rate in the non-cataract surgery group. They adjusted for issues such as smoking, alcohol use, Body Mass Index (a measure of a degree of excess weight), and physical activity. Controlling for those factors means that the higher death rate in the women who did not have cataract surgery cannot be explained or blamed on them having a higher rate of smoking, alcohol use, being overweight or being less physically active.

Although the authors excluded any of those above factors for the mortality difference they did not have any specific reasons as to why this difference exists. There just may be some inherent reason why having better vision leads to a healthier existence and therefore a lower risk of death.

Why are these results important? They demonstrate that there may be an additional benefit to having cataract surgery besides the improved vision (which is enough of a benefit on its own) as it may also help you to live a longer more enjoyable life.
