Temporary blindness tied to smartphone use in dark

The more I hear about the bad effects of constant cell phone use the more I'm glad I don't even possess a cell phone.

This is not really a "cell phone" bad effect, anyone looking at a light at night will lose the night vision, if you use only one eye this effect is easily noticed since the other will still be adapted to darkness (its the cliche for the eyepatch of pirates being used to get one eye used to darkness). If you look at anything illuminated using only one eye you will have the same effect, be it TV, a book, etc. As long as you use both eyes you will not notice anye blindness (since both eyes will be equally blind in darkness).

At night I Arden use mi hone ! No priblemzb at l
