I have had iritis for the last three years, now developing cataracts and an area of retinal thinning that has to be watched. I have had to live in near total darkness, with the wrap around dark sunglasses on day and night, avoid going outside and avoid using electronic devices. I have been trying to find a way to use a computer without being limited to 15 minutes of reading---image type things bother me less. I have dimmed my screen as much as I can, and I have removed the blue light. Thank you....
