Telescopes

Excerpt

The telescope is an instrument that improves the quality of an object's resolution by increasing the image size projected onto the retina. By increasing the size of the image on the retina, this instrument makes it appear closer. Telescopes are devices used in low vision to enlarge the dimensions of images without increasing the distance between the observer and the document or object of regard. Conventional lenses can correct basic refractive errors. For cases when conventional lenses cannot help, there can be a need for more sophisticated optical devices that improve the daily living of individuals with deficient vision.
