I want to ask why my eyes don’t glare when I see the sun then why after seeing the sun directly my head hurts and my eyes feel tired.

1 Answer:

Hello, thank you for the question to HealthReplies.com

Basically the eye has a physiological mechanism to regulate the amount of light entering the eye. This arrangement is done by the pupils of the eye which can enlarge when the conditions around you are dark and shrink when seeing the conditions around you are bright or you see very bright light. It also helps protect your eyes from being too bright when seeing bright lights such as seeing lights or the sun.


Even though your eyes have this mechanism, seeing the sun directly is very highly not recommended. Why is that? Because the sun emits UV radiation that can damage your eyes. This damage can occur directly (your eyes may turn red and feel painful due to the "burns" caused by this radiation to your eyes), it can also occur slowly such as causing pterygium, causing macular degeneration, and also cataracts.


Therefore, in addition to avoiding excessive sun exposure on the skin (by using sunscreen for example), you also have to protect your eyes from excessive sun exposure (for example, use anti-UV glasses when leaving the house in the hot daylight), or use protective like a hat.

So much information from me, hopefully enough answer
