Carpal Tunnel Syndrome Carpal Tunnel Syndrome is a pinched nerve in the wrist. (CTS) is the inflammatory disorder that is caused due to repetitive stress, physical injury or any other condition that causes the tissues around the median nerve to inflated. Actually carpal tunnel is a small canal or tunnel runs from the forearm through the wrist. Bones form three walls of the tunnel, which are bridged by strong, broad ligament. The median nerve passes through this tunnel, which actually supplies feeling to the thumb, index, and ring fingers, the nine tendons that flex the fingers and also provides function for the thenar muscles, which are actually the muscles at the base of the thumb. When the protective lining of the tendons within the carpal tunnel inflamed and swell or when the ligament that forms the roof becomes thicker and broader leads to Carpal Tunnel Syndrome. The result is compression on median nerve fibers due to the swollen tendons and thickened ligaments; there will be slow down in the transmission of the nerve signals through this carpal tunnel.

Using computers for extended periods can cause visual discomfort, headaches and vision challenges. It is very unlikely that you will suffer permanent changes or damage to your eyes. Rather, you may experience these symptoms whenever you use a computer intensively for periods of a couple of hours or longer; the symptoms will diminish soon after you stop working on the computer. Typical symptoms of vision challenges include: Eye strain refers to ocular fatigue, eye discomfort and headaches associated from intensive use of the eyes. Common causes include: glare on the computer screen poor visual correction (out of date eyeglass prescription) reading small character sizes on the screen poor contrast between text and background on the monitor noticeable screen flicker dry eyes Blurred Vision & Dry, Irritated Eyes Computer Vision Syndrome
