But seriously.... recently I read about something that can happen. People use a computer for a few hours, then get up and walk around, and then they can't see very well. Of course they get worried. So what's happening? While using the computer (or reading, or doing anything close up), they eyes get used to focusing at that distance. They sort of stick like that. Then when you start looking into the distance it takes time for the eyes to change back to their normal behaviour. If you are alrady a bit worried, this can be quite a scare, and that makes you notice the problem more. After a few minutes, the eyes readjust to normal distances and start working fine. I don't know whether or not there is any bad effect from this over a number of years (I'm not a doctor), but I do know that worry makes it harder to see clearly. Also consider that the eyes go through changes at different rates at different times of life. For example there is a period some time during late teens/early twenties when short-sighted people will notice much more rapid deterioration, and another around the early 40s where most people, particularly long sighted people, notice another wave of deterioration. The eyesight remains relatively constant in between, so it's easy to become more anxious than necessary if you're not aware of these natural age-related changes. Anyway, the easiest thing to do is go get your eyes checked out. You'll get some proper advice, correction if necessary, and a clear conscience. -- Regards, -*Sue*- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-chat" in the body of the message
