Although not yet severe, my cataracts are bad enough that I have gone to an ophthalmologist for tests and consultation.
My BIG concern is whether one of the "higher end' replacement lenses work as well as advertised, especially since I enjoy photographing birds and other wildlife and I enjoy working on the photos, using my computer.
So, after agonizing for a long time, it hit me. Where else could I find a large number of older photographers then right here at my favorite photo website (I know, not everyone here is that old, ...yet).
So, my own options are:
- Update my eyeglasses to the latest prescription. While doing the eye tests, I could see that a significant part of my problem was the old prescription, going from 20/40 or worse to better than 20/20 and the chart was, then, really sharp. This does not cure the effects of cataracts, but helps with general vision.
- Going with Monofocus replacement lenses. Since I have always been near-sighted, I would go with near focus and continue to wear glasses with graduated lenses, but I would no longer be suffering from the mild to mid de-contrasting effect of cataracts.
- Go with a new product that was recommended by the Dr., called Acrysof IQ Vivity, which uses a "wave-front shaping technology" to get a larger DOF, so that most people don't need glasses from distance to as close as a computer screen. They saw "over 90% reported that they were satisified with their vision". From their data, it they say that about 94% reach 20/25 or better, but I question what the percentage would be at 20/20 or better. They also say that it is just about as good as monofocus lenses at the focal point that they are made for. From what I have read and what the Dr. said, they are significantly better that the previous generation that uses different light paths to split up the incoming image into three focal planes. These result in 1/3 the amount of light and some small aberrations. I am a little worried about bleeding edge products.
The level of cataract-effect I have is enough to make it uncomfortable, but not debilitating to drive at night and I find that i use the rim of my baseball hat to help reduce glare when looking for birds on a sunny day. Most times I can see birds as well as my wife, but with not as much detail. Looking through the view finder, I see no effect of cataracts (evf).
I am currently considering updating my eyeglasses and waiting another year or two.
Anyone have any experience they can share? Thanks in advance.
