Everyone knows that sunglasses are recommended. However, have you ever stopped to consider why? Some people are very sensitive to sunlight and cannot imagine being out in the sun without sunglasses. Others feel that they are unnecessary and may even interfere with clear vision. The truth is, the sun emits harmful rays. Let’s look at how the sun negatively affects our eyes:
Ultraviolet light is high energy light that can cause damage to human tissue. UV affects mostly the eyelids and the front half of the eyes. Cataracts, skin cancer, corneal and conjunctival damage, and other chronic conditions of the eye can be linked to UV exposure.
Blue light is a high energy light, slightly longer in wavelength compared to UV, that can cause damage to the back half of the eyes. Changes in the retina, especially the macula, can be linked to blue light exposure. With the increase of electronics and LED lighting, blue light has recently become more discussed in the media as something to be concerned about at any age.
Glare is a common problem that is caused by wavelengths of light being scattered and washing out color saturation. This is of special concern while driving. Fishermen and photographers have known for years about the benefits of polarization. As more people experience polarization in their sunglasses, it has become associated with high quality sunwear. Anyone who drives a vehicle will see the benefits of polarized lenses.
Sensitivity and eyestrain often go untreated because many just accept it as normal. Individuals with blue or green eyes will have more sensitivity to the sun than those with brown eyes. The reason for this is that those with blue or green eyes have less pigment in the eyes. A degenerative disease known as macular degeneration is more prevalent with people who have less pigment. Even though everyone should be concerned about sun damage to their eyes, those who have sensitive eyes tend to be more inclined to see the necessity of wearing sunglasses.
When shopping for sunglasses, what are some things to consider? Sunglasses can be bought just about anywhere. The quality of sunglasses varies greatly as does the price. Poor quality sunglasses will claim 100% UV protection, but that is about all they provide. Poor materials and manufacturing will lead to discomfort and eyestrain. High quality sunglasses will protect your eyes from UV, blue light, and glare. Optical grade sunglasses will also enhance your vision. Some of the sunglass companies have their own labs making it possible to get their patented lenses in your prescription. Maui Jim, Costa, and Ray Ban are a few of the most well-known companies which have this capability.
The style of sunglasses should not be overlooked. Who doesn’t want to look great in their sunglasses? The quality of sunglasses can be all over the board and it is difficult to know what qualities to look for in selecting your next pair. How is one to know what sunglasses designer to choose?
As eye care providers, we recommend relying on those who are in the business of protecting your eyes and enhancing your vision. Optometric physicians and licensed dispensing opticians are educated and skilled in providing answers to questions about vision and eye health. Some fashion designers will license their name to a sunglasses manufacturer without consideration of the quality. When you select a pair of sunglasses, it is the quality of the frames and the optical clarity of the lenses that we pay attention to the most. Fashion is very important in your decision, but the comfort of the frame and the visual comfort and optical quality of the lenses should rank at the top of your checklist.
