What are the signs of a party need specs?
I figured out I needed to wear eyeglasses when things started to look fuzzy.
blurred vision and headache when u try to see something those are the chief signs
probaly if you can't see
1st age aftere45 check for near figment of the imagination
2nd watering from eyes
3rd feeling irritated after reading
4thfeling exhausted impulsive
and 5th offcourse lasly not able to focus properly
or not competent to read
headaches, squinting, blurred mirage, holding objects too close / far to read them (they need to be within just the right place to see them clearly) difficulty driving at dark, depth perception inaccuracy.
