Display screen technology could correct vision problems (BBC)

[eppur_se_muova]

Engineers have developed a prototype tablet display that compensates for an individuals' vision problems.

The system uses software to alter the light from each individual pixel on the screen, based on the person's glasses prescription.

The researchers also added a thin plastic pin hole filter to enhance the sharpness of the image.

The team say the technology could help millions who need corrective lenses to use their digital devices.

Around one person in three in the UK suffers from short-sightedness or myopia. In the US, around 40% while in Asia it is more than half the population.

(Well, they're conceptually related, however different the actual technology.)

1. I found the best way to use my digital screen

was to take my glasses off completely. The last surgery made me nearsighted in both eyes, meaning I can do close work now without glasses, instead of needing drug store magnifying lenses over bifocals to see work held under a magnifying lamp (when I go blind, I don't fool around).

While it's a total PIA seeing only fuzzy shapes without the glasses, it's great being able to read and play witless games on the Kindle.

2. How about astigmatism ?
