Experts warn against eye damage linked to unprotected viewing as the solar eclipse captivated millions.
The American Academy of Ophthalmology underscores the peril of gazing directly at the sun during the eclipse, stressing the potential for retinal burns and serious vision complications.

Understanding the Risks of Solar Eclipse
In response, NASA and medical authorities advocate for using eclipse glasses or approved handheld solar viewers during the celestial event on Monday, April 8. Dr. Nicole Bajic, a surgical ophthalmologist affiliated with the Cleveland Clinic, underscores the significance of shielding one's eyes to prevent enduring visual impairment amidst the excitement of this rare occurrence.
Despite the common belief that the moon completely blocks out the sun during an eclipse, it's crucial to remember that harmful rays of sunlight can still penetrate and cause damage to your eyes.
Doctors caution that even brief glimpses of the sun during an eclipse can lead to temporary or permanent damage to the macula, a critical part of the retina responsible for central vision.
Posing Threat to Eyesight
Once retinal tissue is destroyed, it cannot regenerate, resulting in irreversible central vision loss. NASA underscores the swift onset of potential damage, noting that a person's retina can be harmed within approximately 100 seconds of unprotected exposure to the sun's intense rays.
This timeframe varies depending on factors such as the sun's intensity and individual differences in ocular health. It's essential to recognize that even during partial phases of a solar eclipse when up to 99% of the sun's surface is obscured, the remaining crescent sun remains potent enough to cause retinal burns.
Moreover, because the retina lacks pain receptors, individuals may not immediately realize the extent of the damage, leading to delayed intervention and irreversible vision impairment.
While it's a common misconception that the moon completely blocks out the sun during an eclipse, it's imperative to understand that harmful rays of sunlight can still threaten your eyesight.
Doctors caution that even brief exposure to the sun during an eclipse, even for just a few seconds, can lead to temporary or permanent damage to the macula, a critical part of the retina responsible for central vision.
This warning comes from medical experts, emphasizing that once retinal tissue is damaged, it cannot regenerate, resulting in irreversible central vision loss.
According to NASA, a person's retina can sustain damage within approximately 100 seconds of unprotected exposure to sunlight during an eclipse.
However, the exact duration varies based on factors such as the sun's intensity and individual variations in eye health.
Even during the partial phases of a solar eclipse, when up to 99% of the sun's surface is obscured, the remaining crescent sun remains potent enough to cause retinal burns.
It's important to note that because the retina lacks pain receptors, individuals may not immediately recognize the damage, and by the time they realize it, it may be too late to salvage their vision.
