You’ve always herd you parents say, “Don’t look at the sun” but how dangerous is it really?
The sun puts out visible, ultraviolet, and infrared light. These ultraviolet rays can harm the cornea of you eye .With overexposure to UV light, the corneal cells start to crack and rip, like a regular sunburn. The eyes can also feel like there on fire and excessive tearing can occur. This tearing happens in order to protect eyes from ripping apart.
Permanent eye damage can occur when someone looks at the sun for 100 seconds or more. Ultimately, how long it takes for damage to occur depends on several factors, such as the dilation of the pupil and the sun’s intensity on that specific day.
