For weeks, experts have been emphasizing the importance of using certified viewing glasses when viewing a solar eclipse. Ignoring this advice could result in permanent eye damage caused by the concentrated rays of the sun.

Dr. Russell Van Gelder, from the American Academy of Ophthalmology, explained the potential consequences, stating that the lenses of the eye can concentrate the sun's rays to the point of causing immediate burns, resulting in a hole in one's vision that may be permanent.

The only safe time to witness a solar eclipse without protective gear is during totality, when the moon completely covers the sun, leading to a period of total darkness. However, observing the eclipse without proper precautions can result in solar retinopathy, a condition characterized by symptoms such as blurred vision, sensitivity, color distortion, and the temporary appearance of "floaters" or "flashers."

According to the Cleveland Clinic, mild cases of solar eye damage can heal on their own within one to six months, but more severe damage may be irreversible. It is recommended to seek medical attention from an ophthalmologist if symptoms persist.

In a case study following the 2017 eclipse, a woman visited Mount Sinai's New York Eye and Ear Infirmary with a complaint of a black spot in her vision. Doctors discovered retinal damage that coincided with the shape of the eclipse, confirming the risks associated with viewing an eclipse without adequate protection.

There is no specific duration of exposure that can lead to permanent damage, as severity can vary based on factors such as cloudiness, air pollution, and the individual's vantage point. However, doctors assert that even a few seconds of unprotected viewing is not worth the risk.

Statistics show that there have been reports of solar retinopathy after every solar eclipse, with a surge in visits to U.S. eye doctors following the 2017 eclipse.

Experts continue to stress the importance of using certified viewing glasses or other appropriate protective measures when experiencing future solar eclipses to avoid potential permanent eye damage.
