Glasses are heading in a new direction to meet the needs of a more technologically immersed society. Many of us are spending more time in front of our screens than ever before, and this is having a direct impact on our vision, mood, and how we operate. Digital screens emit a characteristic blue light that can change the activity of the brain in subtle ways. Companies are now engineering their vision spectacles to filter out this light, in addition to being more compatible with digital screens. This increase in light filtering glasses may imply that these will become the standard form of eyewear in the future.
Reviews for the glasses have been very positive, with some commenting about the health benefits. Indeed, by limiting the harsh lights emitted by computer screens, we will notice improvements in ourselves. It’s important to recognize that digital screens are not natural. They put our eyes under strain for prolonged periods of time. The blue light mimics the blue light from the sky, which is a sign to our brain that it is daytime, and we should stay awake. The glare that is created from a contrast from the digital screen and the environment forces to the eyes to focus more, which leads to more eye strain.
The glasses work to tackle all these issues. The polarizing lens selectively filters blue light, as well as uneven sources of light to create a natural viewing environment. This helps our body recover from symptoms associated with viewing digital screens including blurred vision, headaches, and even poor posture. The lenses work to refocus your field of depth through careful refraction. Digital screens are usually not in the viewing plane as your eyes, so this naturally forces us to tilt our head or bodies forward, resulting in poor posture.
For people who may be concerned about how the glasses appear, they look like regular glasses and do not have an industrial look to them. Like regular glasses, they can be customized by different parameters including any frame fit, lens size, and color. Older light filtering glasses will have an orange tint to the lens and are bulkier in appearance.
Some companies offer a blocking coating for the glasses. It is described as an additional attachment which will further help to reduce glare without changing the color viewed through the glasses. The attachments work by changing the curvature of the lenses, to keep the light entering the lens consistent.
For its technology, the glasses are very affordable, and companies are working harder to use less expensive components in making their glasses. Certain professions may require more robust glasses because these glasses possess a stronger filter.
The glasses may prove as a necessary solution for working with digital devices longer. Some of the technology is still in the preliminary stages, however, the glasses are promising. They are versatile and work with prescription contact lenses as well. The wide range of options they present make it a popular choice for many.
