Because of using the internet on the phone during the day.
I used to be fine with it but now i feel and look like ive got a blackeye (bit its very red) and so itchy.
Its never both eyes, just one.
Why is it doing it? Ive had it over 2 years on and off but ive had the phone internet for years.
I wear glasses but not often enough. Maybe thats the cause???
