    After my opthomologist told me that I had lost pigment in the retina's of both eyes, indicating the future development of macular degeneration, I researched all the information I could find on the condition. Everything I read said UV rays are harmful to the retina and that we should always protect our eyes from these rays. Since I had no way of knowing how much protection my skylights provided I had the Fuison Filter Skylight System installed in all 3 of my skylights. An added benefit is reduced glare and heat transmission.
