My Worries

I use my glasses for everything, can't see that far or read well but there is always a concern. I like to read, be on the pc, look at images and do a lot of activities but unfortunately my eyes hurt and I end up crying they are very sensitive. the point is at my age I already been wearing them for a long time kind of feel naked when I don't. I don't know how good is going to be my vision later on when I get older  *?*
