What's The Difference Between Computer and Blue Light Glasses? — iCare Family Vision? ›

Blue light glasses for daytime are clear and they provide protection from computer screens. Hence they can be called computer glasses. Blue light blocking glasses for nighttime are tinted and they should block 100% of blue light and 100% of green light across the entire spectrum to be effective in promoting sleep.

Blue light glasses come in two varieties: daytime and night-time. Daytime glasses are clear and sometimes referred to as computer glasses since they function in the same way as those stated above. Night-time blue block lenses are coloured — commonly red or orange.

Distance: Consider the distance at which you typically use your digital devices or read. Computer glasses are usually optimized for the distance between your eyes and the computer screen. Reading glasses are designed for a closer range, usually around 14–16 inches.

It may help you see better at work or while reading. You can also make customizations in your regular eyeglass lenses by introducing bifocals, trifocals, multifocal or progressive. On the contrary, computer glasses are designed to protect the eyes from artificial blue light that is emitted from digital screens.

As mentioned before, wearing bifocal glasses often forces a computer user to tilt the head back to focus on the screen through the lower part of the bifocal lenses. Such a forced position can cause neck, shoulder and back pain.

Most people's computer screens are set up roughly two feet away from their face, but the exact distance will vary from person to person. That's why glasses for computer use are typically a custom prescription—to provide the best possible viewing experience for each person's needs.

Several studies suggest that blue light-blocking glasses do not improve symptoms of digital eye strain. The American Academy of Ophthalmology does not recommend blue light-blocking glasses because of the lack of scientific evidence that blue light is damaging to the eyes.

“The American Academy of Ophthalmology states that you don't need them, and it doesn't recommend any special eyewear for computer users.”

For a computer screen, or arms length distance, you would generally use half of the add power prescribed on your Rx for the computer glasses. You would then take half of the add power +2.00, which would be +1.00, and then add it to the SPH (or Sphere) of the prescription.

Unlike readers, bifocals, or regular progressive lenses, computer lenses are specially designed to help you see your computer screen with much less strain and effort. Because of this, they're unique and have some benefits that your other eyewear may not have.

Which glasses are better for computer? ›

Ans. The best glasses for computer use are those with anti-reflective (AR) coating, which helps reduce glare from the computer monitor and prevents UV light from damaging your eyes.

We recommend purchasing computer reading glasses in a power that is half of your standard reading power.

Ask for Blue Light Glasses Brand Spectrum Report

To find out if your blue light glasses are the best computer glasses available you first need to contact the company you bought them from and ask for a spectrum report. This spectrum report will show you the amount of blue light they are blocking.

A major blue cut lenses disadvantage is that the lenses have a bluish reflection. The lenses of blue light filter glasses exhibit a little bluish sheen since they are designed to reflect this blue light. This isn't something you'll notice when you're wearing them, but it's a feature that others will notice.

The short answer is no, blue light glasses will not damage or hurt your eyes. In fact, they are built to do the opposite. The real problem is the excess blue light we receive from our screens, which has been scientifically proven to cause digital eye strain, disruption to sleep cycles, and mental fatigue.

Wearing blue light glasses isn't harmful to your eyes, so you could wear them all day if you wanted, but it may not eliminate digital eye strain entirely. Digital eye strain may not be caused by blue light. While your devices can lead to eye strain, it's not clear whether blue light plays a role in this.

Blue light glasses go by a few different names. You might hear them called blue light blocking glasses or blue light filter glasses. Sometimes, they're just called blue blockers.

Best Overall

Benicci Blue Light Blocking Glasses are durable, comfortable, and effective. We love that they're lightweight, well-fitting, and well-made so they won't cause any added strain while you wear them.

The clear lenses filter only a portion of the blue light spectrum (about 400 to 440 nm), typically around 20% to 40%. However, since these shorter wavelengths have higher energy, that may be all you need.

Although there isn't convincing evidence that blue light glasses can help with eyestrain for computers, some research shows that they may help with sleep. Blue light affects the body's sleep and wake cycle called circadian rhythm, according to the American Academy of Ophthalmology.
