If you do things in the dark such as read, write, or watch TV, are your eyes going to have problems later on?

Question

If you need to squint your eyes?

If you don't have to squint your eyes?

Answer 1

It doesn't cause long term bad effects... however it just makes you tired and gets you headache cuz it causes fatigue of eye muscles...

but surely it is not known to be the cause of any serious long term disease of the eye...

and -contrary to the general beleif- it doesn't worsen you refractive error or get your glasses thicker nor is it the cause for any worsening of eye disease... except for fatigue and headache...
