This seems to be the most FAQ today since more and more time is spent reading at the computer and just about everyone is experiencing discomforting eyestrain. Depending on how many hours you spend at the computer, computer eyestrain can affect your quality of life. Read on for answers on how to reduce your computer eyestrain.
Selecting computer reading glasses requires careful analysis in order for them to be helpful in reducing eyestrain and give you the clearest vision. Computer reading glasses are reading glasses whose lens strength is determined by the distance you view your computer screen and are used specifically for reading at that distance. Traditionally reading glasses were measured for book reading distance which is typically 14-16 inches. Now since reading is done at so many different distances it is necessary to determine the distance at which you intend to use your computer reading glasses to get the correct lens strength that will help reduce your computer eye strain.
Just to make sense of this, choosing lens power is based on the scientific principle that focal power is inversely related to focal length so the further away you hold your reading material the less lens strength you need to see clearly. Working at a computer screen at 18” will require a different lens strength than working at a computer that is 25” away. Coatings and special lens treatments will make no difference if you are not corrected accurately. An anti-reflective coating eliminates distracting surface reflections which is associated with most computer related work. Eliminating glare with an anti-reflective coating and making changes to your surroundings can greatly help cut down on computer eyestrain. More research needs to be done to establish any true benefits to blue light blocking computer reading glasses.
Sometimes a more personalized correction is necessary. If that's the case, I recommend measuring your reading distances before you get your eyes examined. Discuss this with your doctor so that you get the correct lens strength in your computer glasses that will work for your specific computer use.
Known as that tired, strained feeling, computer eye strain or as it is technically called, Computer Vision Syndrome (CVS), has become more common place today as we spend hours, day after day in front of the computer. CVS is usually characterized by fatigue, redness, irritation, burning or dryness and even double or blurred vision. Many of the symptoms of computer eyestrain can be alleviated by making adjustments to your work environment, optimizing computer monitor settings, and using reading glasses for your specific computer distance.
