Computer Glasses: Why You Might Need Them
After a long workday in front of the computer, your eyes may feel irritated and dry. That is why you may want to invest in a pair of computer glasses. Contemporary workplaces are full of computers and digital devices. Indeed, most people could not live without their devices at work or even at home. However, these devices can cause stress to the eyes.
Reasons you Might Need Computer Glasses
Vision issues are one of the hazards of too much screen time. Studies even show that using digital devices for hours at a time can cause some type of digital eye strain like dry, strained, or red eyes, back pain, blurred vision, headaches, general fatigue, and neck pain. You can prevent or minimize strains by taking your eyes off the computer screen after a few minutes of working and ergonomically optimizing your optimization. Apart from these solutions, glasses that protect your eyes might also alleviate or prevent digital eyestrain.
How Computer Glasses Work
These special-purpose glasses optimize your eyesight when you are looking at digital screens to work or play games. They are designed to minimize glare, increase contrast, and maximize what you see through the lenses. As a result, you will be able to easily look at the screen for longer periods of time. Computer glasses have the following features:
- Anti-reflective coating. This feature decreases the glare that bounces off the screen and from light sources. Specialized designed gaming and computer glasses provide anti-reflecting coatings. Eyeglasses with premium anti-reflecting coating help in making sure your vision remains clear by keeping fingerprints and dust from appearing on the glasses. Try to find glasses that include a small bump that offers enough of a power boost to allow the print on the screen to become slightly bigger, therefore, reducing eye strain.
- Color tints. Some computer glasses come with a tint designed to increase the contrast on the screen and filter out the harsh light spectrums to allow your eye muscles to relax.
Blue Light and How you are Exposed to It
The visible spectrum of light is composed of a range of colors, from red on the higher end to blue-violet on the lower end. That light you see on the lower end has the shortest wavelengths while the light on the higher end has the longest wavelengths. Shorter wavelengths tend to emit more energy, thus, blue light is called High Energy Visible (HEV) light.
Blue light exposure happens on bright sunny days. However, even if you stay indoors, you are still not immune due to your exposure to unnatural blue light from your TV, smartphone, artificial lighting, and computer screen. While your digital devices emit just a fraction of the HEV light emitted from the sun, spending many hours with your devices can have a cumulative and immediate effect on your eyes. Being exposed to blue light is a concern. Too much of this light can lead to high blood pressure. In fact, it can cause sleep disruptions since blue light regulates your sleep/wake cycle.
