Whether you use computer monitors for work or play, the health benefits of using a pair of screen glasses are undeniable. However, not all screen glasses are created equally. Many computer monitor screen glasses offer little to no protection, while other glasses offer significant protection from glare and eye fatigue. In this article, we’ll take a look at some of the most common types of computer monitor screen glasses and how they compare to standard glasses for comfort, safety and vision correction.
Blue Light Screen Glasses
The first type of monitor screen glasses to come onto the market were blue light filtering computer glasses. These lenses block out the majority of visible light, which helps to protect the most vulnerable parts of the eyes. Blue light is extremely distracting and can cause eyestrain and headaches, as well as discomfort and nausea. They also block out high-intensity rays of light that can damage the eyes by causing long term damage. These days however, there are a wide range of coloured screen glasses that help protect the eyes while still offering decent vision correction.
Corrective Glasses For Screens
Next on the list are corrective lenses, which correct vision for near and far sightedness, but also filter out high-intensity blue light. For example, there are some glasses that are made with a combination of near and far corrective lenses, so that one can see both sides of a scene at high magnification. This type of lens is often called a binocular, and works best when viewing small images like photos or small paintings. Because these lenses are not used for seeing objects at high magnifications, they offer very little protection to the eyes in terms of glare. As they are worn for extended periods of time, it is likely that they will become smeared and dirty.
Amber Coloured Glasses
Finally, there are amber colored tinted lenses that, much like blue light filtering computer glasses, block out more visible light, only allowing a small portion to penetrate the eye. Often these types of glasses can be found in settings that use infra-red rays, or red-yellow laser rays, which are able to target light at specific wavelengths. These rays are more commonly associated with eye conditions. The downside to amber tinted screen glasses is that they filter out so much light that they change colour perception a lot, so are not good for all applications.
Which Screen Glasses Do I Need?
One of the main choices to make when purchasing screen glasses is whether to choose those that offer just basic protection, or those that offer more complex levels of protection. Basic types of blue light eyewear are those which filter only blue light. These are great if you work in front of a computer or spend a lot of time using your phone, like many people nowadays do. If you are subjected to much stronger forms of artificial light, for example fluorescent light or high energy lasers, you might want to opt for the stronger amber coloured lenses.
If you choose to use digital eye strain relief technology with prescription glasses, it is important to note that this type of operation should be performed by an optometrist or ophthalmologist. While many individuals are comfortable with the use of these prescription glasses to reduce the effects of glares, they should also be used in conjunction with these blue light technologies. Although blue light filtering is safe and effective, it can cause some discomfort for the wearer, so an eye doctor is always best suited to perform the procedure. In addition to reducing the effects of glares and allowing for improved vision, prescription glasses with these blue light filtering lenses can also help prevent dry eyes and other problems that can arise from wearing spectacles or corrective lenses for prolonged periods of time.
