Looking at my young, pre-puberty photographs, it looks like the same color as my pupil, ~indistinguishable in color like the medical condition of Aniridia. they were indeed WAY DARKER than they're now. My dad started with the black iris color too, now turned golden yellowish colors. My mom doesn't read from screens that much, except watching one hour of TV per day or so. Her iris remains black or a very dark brown, difficult to tell where iris begins and where pupil ends even just sitting from across the table.
I've also noticed that when I stopped using computer/screen-staring for an extended period of time , like on vacation for a couple of weeks or only using computer/TV very sparingly for some weeks while just reading from paper/printed material like when it happend occasionally during teen years, my eye colors seem to grow darker. There are also slight variances after a well rest/ long sleeps. The longest "experiment" i did on this was about a month or so and they reverted back a bit. Could also be due to the tanning effects! as the pigments tend to build up like skin darkens under tanning. My eyesight also deteriorated, now nearsighted/myopic though both parents and all grandparents had normal visions. I experimented with both glasses/contact lens, sometimes only wearing glasses all day in school for a month and sometimes only contact len s throughout the day, . I think the contact lens wearing/solution chemicals etc also contributed to eye color changes.
I've heard people's eye changes also change slightly for a short time when angry or experience other extreme emotions/mood swings. I haven't tested that on myself. They only change slightly due to my level of rest/relaxation/health conditions and status, definitely getting less and less pigmented as a general trend . At this rate, they'll be golden/yellow/amber/"hazel within 5-10s years! just a bit concerned about diseases
like threadstarter, not that worried, just on exactly why they changed and still seem to be changing gradually.
