Eye doctors warn of possible vision damage after UK eclipse viewing

Following Wednesday's partial eclipse, eye experts warned that unprotected viewing can damage the retina, resulting in solar retinopathy that often goes unnoticed at first. Typical signs include a grey or yellow central spot, blurred sight, increased light sensitivity, redness or a gritty feeling, and these may emerge a few hours after exposure. Alexander Ionides, a consultant eye surgeon at Moorfields Eye Hospital in London, said the condition is painless and recommended urgent assessment through local opticians or hospital eye services.

He noted that retinal scans can detect the injury and that patients can be referred to eye casualty units. Compared with the 1999 total eclipse, the number of inquiries to his hospital has been considerably lower, suggesting public warnings may be effective. Authorities continue to stress the use of certified solar eclipse glasses rather than ordinary sunglasses.
