Do You Need Computer Glasses? San Fernando Valley - Dr. Barry Leonard (2024)

FAQs

Are computer glasses really necessary? ›

There is no scientific evidence that the light coming from computer screens is damaging to the eyes. Because of this, the Academy does not recommend any special eye wear for computer use.

Generally speaking, bifocals are not necessarily designed for computer work. They tend to force the wearer to tilt the head back in order to focus on the screen while looking through the lower segment of the bifocal lenses.

You can get a specific prescription for computer glasses. (There are also non-prescription computer glasses too.) These glasses simply have special filters to help reduce eye strain when using computers or other electronics.

Zero power lenses with blue block features are the computer lenses to block blue light. These computer glasses are coated with blue ray protection to protect your eyes and can be used by everyone. If you use prescription wear with high powers, you should go for blue-ray protection coating with your power lenses.

Disadvantages of Wearing Computer Glasses all the Time

Computer glasses can make you more myopic (nearsighted) and astigmatic (blurry). This means that the eye lenses in your computer glasses will distort the light coming into your eyes from near objects or far objects so that you don't see them as clearly.

Use computer glasses when using a digital screen which is around 24 inches away from your eyes. You may choose to use computer glasses that have blue-light filtering. Use reading glasses when reading books or printed documents, which are usually held much closer, about 15 inches.

Most eyeglasses are designed to optimize distance vision — usually defined as 20 feet away and beyond. Most bifocals and reading glasses are designed to give focused vision — about 14 inches from the eye. A computer monitor sits farther away than where your bifocal can focus but is too close for distance correction.

Trifocal. Trifocal lenses are a good choice for blocking blue light generated by computers. The lenses are normally utilized to treat eye conditions, such as presbyopia. If the lenses are prescribed by an ophthalmologist, the patient must request filtration for blue light blocking.

When using lenses with a single focal range (ie: for distance or reading) the top of the screen should be positioned at eye level or slightly below and at a distance where you can read without eye strain or leaning forward.

When should I buy computer glasses? ›

If you're constantly struggling with eye strain, feel pressure on the outside of your temples, or get light headaches after sitting in front of your desk, it may be time to try out computer glasses.

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.

Computer glasses won't entirely prevent digital eye strain but they can help reduce your symptoms. While blue light filters do block it from reaching your eyes, there is no concrete evidence blue light harms your eyes. Some professionals recommend them despite this.

A lot of us wear glasses to correct vision problems. But regular eyeglasses are not the same as computer glasses. Computer reading glasses are specially made to help reduce eye strain. They have an anti-reflective coating to help reduce glare and a tint that helps increase contrast for easier viewing.

It typically takes two or three days for a person to adjust to new glasses, but sometimes it can take a week or more.

Look at a Spectrum Report

Most companies that sell blue light glasses will have a spectrum report on hand that shows how much blue light the glasses actually filter. This is the only way to know for sure whether or not your glasses are actually blue light blocking glasses.

Yellow-tinted lenses enhance depth perception and increase visibility in low-light situations, making them a top choice amongst safety glasses. Yellow lenses are also used in computer readers, as they help to soothe strained eyes and combat the negative effects of Computer Vision Syndrome.

The most common issue is a slow adjustment period. It can take weeks to get used to progressive lenses, so if you notice any distortion while driving, work your way up to wearing them full time. For anyone who requires three prescriptions for eyeglasses, progressive lenses are the way to go.

Progressive lenses allow you to see at all distances with one pair of glasses. They start with your distance prescription (if you have one) at the top of the lens and increase as you move toward the bottom of the lens. You simply move your head position to allow you to focus through different areas of the lens.

The strength of progressive lenses is actually the factor that leads to initial peripheral blurriness. Progressive lenses tend to be blurry on the sides because each lens promotes three fields of vision: An upper lens segment designed to help the wearer see objects in the distance.

Cons of Blue Light Glasses

The blue cut lenses alter the colour of everything you see in the yellow hue. Another blue cut lenses disadvantage is that they are unable to protect skin that also contains melanopsin, a photoreceptor that tells your body whether it is day or night.

Rest breaks.

Resting the eyes for 15 minutes after two hours of continuous computer use. Also, for every 20 minutes of computer viewing, look into the distance for 20 seconds to allow the eyes a chance to refocus.

Companies that are selling these glasses often claim that they decrease digital eye strain, help prevent eye disease, and improve sleep. However, The American Academy of Ophthalmology doesn't endorse or recommend using blue-light-blocking glasses because there is no scientific evidence that they do any of these things.

According to the American Academy of Opthalmology (AAO), there is no credible scientific evidence that the light from digital screens is harmful. Therefore, the AAO does not recommend people use blue light glasses.

“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. ” In short, there are other factors in play that may be contributing to your eye strain.

Computer Use

Anytime that you are using a desktop monitor or laptop computer you should be wearing your blue light blocking lenses. Many employees spend at least eight hours a day looking at a computer screen. That is a lot of time to be exposed to the blue light that is emitted from the screens.

And the simple answer is, yes. Blue light glasses will not affect or damage your vision if you're wearing them throughout the day time or outside. However, it's important to note, that blue light in its natural form is actually a good thing and can be found in the sun's rays.
