An eye examination at McKenna and Scott Exclusive in Pinelands is not merely about finding a prescription. It is about eyecare, eye health, patient education and friendly service. Vision is not merely about the clarity of the image. It is about how both the eyes work together as a team ie. eye alignment, the contraction and relaxation of the individual eye muscles and ocular movements. These factors affect our visual performance and comfort throughout our daily tasks and activities. The majority of eye diseases are painless and can go undetected for years, leading to possible irreparable damage. Also, certain eye conditions can be manifestations of underlying systemic diseases. All these aspects of vision and health are part of our comprehensive eye examinations.

Adjust your workstation and chair to the correct height so your feet rest comfortably on the floor. Position your computer screen so it's 40-60cm (20 to 24 inches) from your eyes. The center
Exercise your eyes. Another cause of computer eye strain is focusing fatigue. To reduce your risk of tiring your eyes by constantly focusing on your screen, look away from your computer at least every 20 minutes and gaze at a distant object (at least 20 feet away) for at least 20 seconds.

Another exercise is to look far away at an object for 10-15 seconds, then gaze at something up close for 10-15 seconds. Then look back at the
Upgrade your display. If you have not already done so, replace your old tube-style monitor (called a cathode ray tube or CRT) with a flat-panel LED (light-emitting diode) screen with an anti-reflective surface. Old-fashioned CRT screens can cause a noticeable "flicker" of images, which is a major cause of computer eye strain. Even if this flicker is imperceptible, it still can contribute to eye strain and fatigue during computer work. Complications due to flicker are even more likely if the refresh rate of the monitor is less than 75 hertz (Hz). If you must use a CRT at work,
