While computers are useful for a number of activities and tasks, there is little question as to whether excessive computer use contributes to physical health problems. The bright lights of the computer screen, the positions in which people sit while using computers and continuous typing can all contribute to various types of joint inflammation and eye strain.

Computer vision syndrome
Computer Vision Syndrome is a strain on the eyes that happens when you use a computer for prolonged periods of time. Anyone who has spent a few hours on the computer has probably felt some of the effects of prolonged use of the computer or other digital technology, according to Bausch & Lomb eye specialists. This can include itchy or burning eyes, blurred or double vision, eye fatigue, headaches from eye strain and bloodshot eyes. Taking frequent breaks to close the eyes even for only a few seconds can go a long way in reducing these symptoms. Additionally, some companies such as Varionet have developed glasses to wear during computer use that are purported to reduce this strain.
Carpal tunnel syndrome
Frequent wear on the fingers and wrists from typing can produce a condition known as carpal tunnel syndrome (CTS) over time. Symptoms of CTS include feeling "pins and needles" or tingling in fingers, numbness in fingers and pain in wrists and hands. Repetitive motions and having the wrists in a bent position both contribute to this condition. Some ways to treat or even prevent this condition include using a support bar for the wrists when typing and taking breaks to flex and relax the hands during lengthy typing periods.
UK researchers have found through a recent survey that as many as 70 percent of people in the UK use computers, with the majority of these computer users experiencing negative health issues. These issues include lower back pain and muscle aches. Important prevention methods include taking breaks to stretch the legs and back, as well as sitting at the computer with proper posture and back support.
