I had cataract surgery two years ago, which includes removal of the natural lenses deep inside the eye. I just looked up the ID cards that came with the implant lenses they installed and they indicate that I have a blue filter and a UV filter included in the lenses. The purpose of these is to protect my retinas from further damage from the sun, so it makes good sense to have these in your shades, especially when on the water. A few weeks after the surgery a young woman asked me what else I have installed in what she called my "bionic eyes", and I told her I also have thermal imaging (heat sensing) filters too, and I added "And by the way, you're looking absolutely lovely today". She laughed at me and said I was being silly, but she did sit up a little straighter in her chair, just in case.

Re: GL: My bad! I've been told that my dry macular degeneration is genetic as is wet macular degeneration. Although there is no real treatment for dry, my doctors have me wear sunglasses outdoors. In Vietnam we found that the wearing of 85% or better sunglasses (the amount of light that they admit) increased night vision by 200%. A good thing for cruisers to know.
