Sunglasses from Noble Vision Center in Greensburg

Many people wear sunglasses during the summer because they love how they look. It's true the right pair of sunglasses can make you look glamorous, edgy, or just plain cool. But did you know that sunglasses do more than give you shade; they are also beneficial to the health of your eyes in several important ways.

Skin Cancer

Skin cancer is caused by exposure to UV rays. And according to recent studies, about 10% of all skin cancers begin in the skin around the eyes. The thin, delicate tissue of the eyelids and surrounding the eyes is vulnerable to UV, and most people miss these areas when applying sunscreen. UV protective glasses are like sunscreen for your eyes. In short, wearing sunglasses can help prevent skin cancer.

Diseases of the Eye

Cataracts occur when the lens of your eye becomes cloudy and must be removed. Although cataracts are a normal part of the aging process, prolonged exposure to UV can contribute to their formation. Glaucoma affects the eye's optic nerve and can result in permanent vision loss, and UV rays are a risk factor for this disease as well. Macular Degeneration is the gradual deterioration of the macula (the area of the retina most important for vision). It is the leading cause of vision loss in those over age 50, and UV protection is thought to slow the progress of this disease.

Snow Blindness

Although many people think of sunglasses as a summertime accessory, sunglasses are also important in the winter. Snow blindness, also called acute photo-keratitis, is a painful condition that occurs when the corneas of the eyes are burned by UV rays reflecting off of snow. We are lucky enough to have several ski resorts in our area, and UV levels can be as much as 30% greater at high altitudes. If you love to ski or snowboard, it is very important that you wear high-quality UV protective lenses.  

Headaches and Migraines

Migraine sufferers know that bright sunlight can be a trigger. Even those who don't suffer from migraines can get headaches from being out in the sun without sunglasses. Squinting against the sun can cause eyestrain and fatigue, not to mention wrinkles! The best way to prevent these issues is to wear UV protective, polarized sunglasses.

Now that you understand the importance of a good pair of sunglasses, how do you choose the right one? There are many lens colors available, and each has its own unique properties. Here is a summary of a few of the most popular lens colors.


Gray is a great choice for general purpose sunglasses. Most people perceive it to be the "darkest", as it can block nearly 90% of visible light. It is also color neutral, meaning colors viewed through a gray lens are true.


Brown is a very versatile shade for your everyday sunglasses. Like gray, it can be very dark, and because brown naturally blocks blue light, it increases color contrast and depth perception. If you want crisp, clear vision with colors that "pop", a polarized brown lens might be for you.  


Like gray, green is color neutral, although it doesn’t block as much visible light as gray. For this reason it is great for overcast or foggy days. Remember, even when the sun isn't bright, you still need UV protection! Most people who put on a green lens say it makes their eyes "relax".


Rose lenses offer the most color contrast of any sun lens color. For this reason they increase visual awareness and depth perception, making them an excellent choice for golf or skiing.


Yellow lenses have the effect of brightening your surroundings while blocking glare, making them ideal for those who have trouble with nighttime driving. Although not for general use, they are also sometimes referred to as "shooter's yellow".

These are just a few of the many choices available for your sunglasses. There are also gradient tints, anti-reflective lenses, and mirror coatings in many different colors. Along with frames built for sports performance, driving, or any fashion statement you'd like to make, the options are nearly endless.
