What Is It Like to Have Low Vision? A New Sight Simulator Can Help You Understand

How the world can lookwith low vision A query I receive frequently from readers is how to describe their low vision or vision loss to fully sighted family members and friends, who may find it difficult to understand how functional vision can vary significantly from one day to the next, or from daytime to nighttime. While some basic explanations do exist (cataracts = blurriness; glaucoma = "tunnel" vision), they rarely suffice, and accurately describing what one can – and cannot – see has remained an elusive and unsatisfying quest. Now, however,

New Research: Automobile Side Windows Do not Offer Sufficient Protection from UV Light, Increase the Risk of Cataracts and Other Eye Diseases

Surprising New Research from the National Eye Institute on Surgical Options for Congenital Cataracts

For adults who undergo cataract surgery, implantation of an artificial lens, also called an intraocular [i.e., within the eye] lens, or IOL, has been the standard of care for many years.

The research, entitled

New Research from Australia: Does Cataract Surgery Increase the Risk of Falling?
