In the same way that sensitive skin needs sunscreen, people who have been diagnosed with macular degeneration, should do all they can to protect their eyes from the sun, especially the macula.
Age-related macular degeneration (AMD) is a degenerative disease affecting the central part of the retina, the macula, whose function is to provide the sharpest visual acuity. Although there are several factors that cause the development of this disease such as genetics, environmental causes, or smoking, it is known that the sun’s UV rays directly affect the macula.
Good UV protection is, therefore, important in prevention of the disease or at least in delaying its progression in patients who have already been diagnosed with the disease.
Although conventional sunglasses filter out almost all of these rays (it would be like using SPF 30 for skin), selective cut-off filters provide extra protection because they completely prevent the passage of ultraviolet light.
In addition, conventional sunglasses sometimes affect visual quality by obscuring vision too much, whereas filters provide better contrast, avoid glare and do not decrease the amount of light perceived. People affected by AMD already have decreased vision so it is important that they wear protective sunglasses to prevent further decrease.
A specialist optometrist can prescribe the best selective cut-off filter for your visual needs, which, in addition to preventing the progression of the disease, will also improve visual quality.
There are, therefore, specific aids for patients suffering from an irreversible visual loss, with which they can improve the quality of their vision. Vissum’s Visual Therapy and Low Vision Unit will help you to make better use of your residual vision and improve your quality of life.
