Wearing Sunglasses

Wearing sunglasses all of the time when you are outside can be harmful to your health, but it is important to use them. Confused? Well, your eyes have receptors in them that trigger Vitamin D absorption when they detect sunlight. If you block the UV rays from reaching your eyes, then it is likely that you will not absorb your daily need of Vitamin D from the sun. However, wearing sunglasses can help to protect your eyes so that they can stay healthier for a longer period of time.  There are many health benefits to wearing sunglasses because eyes that are regularly exposed to too much sun can develop serious and sometimes permanent damage.

First of all, when picking out glasses, you must make sure that you are not just picking out the “cool” glasses that do not block the UV rays.  There are plenty of sunglasses out there that look snazzy that also do their job as eye-protection. Cheap glasses can actually do you more harm than good. For instance, if you have sunglasses that do not have any UV ray protection, then you would, obviously, increase your disclosure to UV rays. Because the sunglasses will keep some of the light out, you won’t realize that you are still exposing yourself to these rays and the UV light could cause damage to the retina. Another risk is that because there is less light, your iris opens to permit more light in, but when you wear cheap glasses, you allow the UV rays in along with the light.

You should wear the glasses if you think that you are outside long enough to get a sunburn or tan. Wearing them will greatly decrease the chance of  age related eye diseases. Some of these diseases include cataracts (cloudy formations on the lens inside the eye), yellowing of the white part of your eye, and photokeratitis (sunburn of the surface of the eyeball– the cornea).

Sunglasses also provide protection from glares. Good sunglasses could releave you from glare using polarization.

Have fun out in the sun, but make sure to protect your eyes from any UV damage!

    The problem is with dark sunglasses, they hurt and help at the same time. over a period of time, I have viewed from personal experience, those of my friends that wear sunglasses all the time, their inability to bear bright sunlight without sunglasses, while I have no trouble at all. Our eyes were designed to deal with bright lights on their own with the iris, but we in our wisdom are weakening that ability by limiting our exposure to bright lights…

    Other than causing you to lose the ability to drive at night and the ability to go outside on a sunny day without sunglasses, you are not hurt at all.
