We made a test:
- A 23 old girl with laser corrected eye sight.
- A 33 old women not needing eye correction (says a recent vision test)
- A 40 old guy wearing glasses
Important is not the age, important is the sensitivity of the retina center. I for example have 130% sharpness there, thus can see much details even in long distance. I dont need a big screen TV to see details in a picture even some meters away.
Autistic persons even have a much sharper visiblitiy - they can see details 20 meter away, which normal people could only see in 7 meters distance. They probably would see every detail on a 19" flatscreen, where others need a 40" TV.
