Recently, I've noticed that I need quite a bit of light to see properly. Natural light works better. When inside, I have to turn on all the lights otherwise I get a headache. I'm 53 years old. Is this normal or something I should be concerned about?
Yes you need to see an ophthalmologist Eye MD for a full medical exam. You could need glasses, need stronger glasses, or could have cataracts or macular degeneration.
