Background technique
With the growth of human longevity and other a variety of causes, the number of people with visual impairment is being increasing.Many books
The word on information mediums such as report is all too small for them not to be seen.Certain vision disorders even can not by band presbyopic glasses come
It solves.Therefore, it is necessary to which other technologies means is taken to amplify font.
Optical loupes are one of main technological means.Its essence is a convex lenses, pass through simple optics
Principle realizes amplification, there is spheric glass and aspherical lens two types.It is at low cost since optical loupes are easy to carry, because
This its using wide.But its right existing defects, and at least two o'clock is insufficient: first is that, for spheric glass, due to taking
The principle of pure optical amplifier, therefore there is inevitably apparent distortion in the edge of mirror.This is in long-time reading process
People can be allowed to generate spinning sensation, it is serious to there is also the adverse reactions such as vomiting;And although aspherical lens are able to solve distortion, so
And and be not thorough, and it is expensive.Second is that the amplification factor of optical loupes needs to change with text or picture size and become
Change, real-time perfoming is needed to manually adjust.And since the brightness of pure optical loupes itself is not also high, reading can be caused very big
Puzzlement.
