content: You dont seem “a little off”, but I would generally agree with Tourgen that it may be some eye or neurological changes that happen as you age. The sun didnt change or shift on the light spectrum in the last 20 years. You could try antidepressants and see if that doesnt revers the phenomenon, though Im not a fan of longterm use of them.  Remember daily sun exposure can cause cataracts, as well as skin cancer long term. White people, especially those with freckles should not overdo it.
