Headaches are a major reason people go for an eye examination.
Computer-related headaches can be caused by a variety of things, including stress, eye conditions, improper placement of the monitor, glare and poor lighting. Since you blink less often during computer use, you may notice having dry eyes, which can cause eye irritation and problems with contact lenses. Check to see that your computer screen is positioned correctly for viewing, is clean, isn't reflecting glare and provides proper contrast. Glare is often the result of direct, overhead lights, especially fluorescent lighting. Most regular bifocals or progressive addition lenses aren't designed for computer use.
