Many of us have jobs that involve using a computer. For some of us, we spend the majority of our working day with our eyes glued to some sort of screen, be it a laptop, computer or smart device. However, doing so is proven to not be great news for our eyes. People who spend excessive amounts of time looking at screens, and in particular those of computers and laptops, can suffer from a range of unpleasant and often debilitating symptoms that affect their day to day life. These are signs of a condition referred to as computer vision syndrome or CVS. Fortunately, there is a solution that can reduce these problems and make it much easier and more comfortable for you to tolerate screen time. This solution is computer glasses.
Computer glasses are prescription glasses that are worn with the purpose of improving your vision when you are using a computer. One of the biggest challenges with viewing a computer is that, in most cases, the screen is further away than you would usually view reading material, but not far enough away to be classed as distance vision. This custom field of intermediate vision means that conventional prescription lenses for near or far-sightedness are usually not appropriate or helpful. Even standard bifocals, which some people recommend for computer work, arent ideal since they tend to force the wearer to tilt their head back in order to see through the bottom part of the lens. Doing this can cause neck and shoulder strain that can simply exacerbate the problem.
The goal of computer glasses is to make it possible for the wearer to be able to use their device comfortably whilst also maintaining clear vision. There are a few different types of computer glasses available.
The simplest form of computer glasses has single vision lenses. However, these have a modified lens power that gives the wearer the most comfortable intermediate vision possible and they will be able to view the whole screen without making any excessive head movements. However, distant objects and those that are at a reading distance will appear blurred.
These computer glasses have lenses split into either two or three distinct sections that are customized for near, far and intermediate vision and will be specific for your individual needs. However, the areas of the lenses are very clearly defined and there may be limitations to the viewing areas.
The most popular type of computer glasses, progressive computer glasses offer greater continuity of vision by eliminating lines between segments of different focal powers. This enables a smoother and easier transition between areas of focus for the wearer.
An anti-reflective coating is recommended for all computer glasses. This is because this coating eliminates reflections of light from the back and front surfaces of the lenses – something which can cause eye strain and fatigue.
An increasing number of computer glasses are now being supplied with photochromatic lenses. This helps to shield your eyes from blue light that is emitted from your screen device. This can also help to reduce the number of symptoms associated with blue light strain – which are very similar in nature to the symptoms of computer vision syndrome.
Some of the most common symptoms of computer vision syndrome include:
Dry, red eyes
