Dry Eye Computers

eye problem, 17 years old, help!?
Im 17, my symptoms are ghosting vision, glare and starbursts.
These occur mainly at night and on high contrasts (like white writing on a black background).
The ghosting vision is worse in my left eye. Also i play on the computer sometimes about 8 hours a day, and normally everyday, also i don’t sleep too much.
I had an eye test, but my vision was fine, its just the problems those problems that i have.
Could this be dry eyes from computer use?
may be dry eye , but also may be retinal detachment or glaucoma , u need to see an ophthalmologist .
