I can't see the board or any thing else from far away and I don't know what to do, what should I do?
Thanks for your Question
There is nothing to worry about. Most likely you have refractive error such as myopia, hyperopia or astigmatism. You have to visit your optometrist for Eyeglasses prescription.
In case you are not comfortable with eyeglasses you can wear contact lenses or after the age of 18 years you can do refractive surgery.
