Hi. I have glasses that I have been wearing for a couple years. This morning I started to have trouble seeing. Things have gotten worst and I am having a hard time typing and / or concentrating. My left eye is twitching and has some pain. My right hand / thumb it numb. I have having trouble typing and am a little confused. Seems like when I am typing (in normally don t need to look at the keys) I need to type things multiple times to get it right. I am having trouble even typing my e-mail address. Please help.
