Learn how to help prevent age related AMD.
What is AMD?
Age-related AMD is a common eye condition that affects millions of people around the world. It is the leading cause of vision loss in individuals over the age of 50. The macula, a small area at the centre of the retina, is responsible for sharp and clear central vision. As we age, the macula can deteriorate, leading to a gradual loss of central vision and, in some cases, complete blindness. Although the exact cause is still unknown, several risk factors have been identified, including age, genetics, smoking, high blood pressure, obesity, and diet. However, recent studies have also suggested that exposure to sunlight and ultraviolet (UV) rays might play a significant role in the development of AMD.
The role of sunlight and UV exposure in Macular Degeneration
Sunlight contains ultraviolet (UV) radiation, which causes damage to the skin and eyes. Prolonged exposure to UV rays can lead to a variety of eye conditions, such as cataracts, pterygium, and photokeratitis (also known as snow blindness). Various studies have shown that people who were exposed to high levels of UV exposure had a higher risk of getting AMD compared to those with lower level. Those studies suggest that protecting our eyes from sunlight and UV rays might be crucial.
Purpose of sunglasses and which to choose
Sunglasses can provide a barrier between our eyes and the sun's harmful UV rays. By blocking out these rays, sunglasses help to prevent the damage that can lead to various eye conditions. According to the American Academy of Ophthalmology, wearing sunglasses that block 99% to 100% of both UVA and UVB radiation can help to reduce that damage.
To ensure that your sunglasses provide the best possible protection, consider the following factors:
· UV protection: Choose sunglasses that block 99% to 100% of both UVA and UVB radiation. This information is usually indicated on the product label or packaging. If the sunglasses do not provide this information, it is best to look for another pair that does
· Polarized lenses: Polarized lenses can reduce glare, which can be helpful in preventing eye strain and, indirectly, macular degeneration
· Lens colour: Grey and green lenses provide the most accurate colour perception, while brown and amber lenses can enhance contrast. Choose a lens colour that suits your preferences and activities
· Frame design: Wraparound frames can provide additional protection by blocking sunlight from entering the sides of the sunglasses. Look for frames that fit comfortably and securely on your face to ensure maximum protection
