Becker, an Eye Specialist, Warns That Even Brief Glances at the Sun Can Cause Permanent Damage to the Retina in Switzerland

Ophthalmologist Matthias Becker can tell precisely whether a patient has ever looked at the sun for too long. In an interview, he explains how one can still experience a solar eclipse without protective glasses, and why supermarket sunglasses are not a substitute. Becker, an eye specialist, warns that even brief glances at the sun can cause permanent damage to the retina. That cannot be repaired, he says, emphasizing that the effects of such exposure are irreversible.
