the inside corner of my eyes are red, and feel strained, i use a computer all day for work and school and also accidently took more then the directed amount of robotusin yesterday, is there anything you can think this can be from. Also, i'm worried about cob webs ( forgot the scientific name) that I've had for a couple months now. -Spotters, or something. Just want advise and what seriousnesses that may occur with everything involved or if some things may not tie together. I've always had 20-20 and don't want to lose my sight.
