Do Computer Glasses Work?
We are spending more time than ever in front of digital screens, and this amount will likely continue to increase. We have all been there, staring, or possibly squinting, at a phone or computer screen for long hours. Our necks are aching and our eyes burning, but the work must be done!
Don’t freight! Thanks to evolving lens technology, opticians are working hard to ensure our eyes can keep up with the digital changes we are facing. You’ve likely heard of computer glasses and their benefits, but do they work?
What are computer glasses?
Computer glasses are designed to ease digital eye strain and computer vision syndrome (CVS) caused by prolonged screen use. There are several varieties of computer glasses, including anti-glare lenses, blue light filters and computer multifocal lenses.
Designed to help you work on devices without worrying about eye strain or headaches, computer glasses can be an excellent solution for those who suffer from common symptoms.
How do computer glasses work?
Computer glasses are designed to reduce eye strain caused by spending too much time in front of our digital devices. There are several types of computer glasses and they all work differently.
DID YOU KNOW?
What is Computer Vision Syndrome?
What is blue light?
Blue light, also known as high energy visible (HEV) light, is a colour in the visible light spectrum that human eyes can see. Although the eyes can see blue light, they cannot effectively filter it, allowing more to pass through the front (cornea and lens) to the back of the eye (retina).
The wavelength of visible light is between 380-780 nanometers (nm). Generally, the shorter the wavelength, the higher the energy. Blue light is within the 380-500 nm range, giving it the shortest wavelength and the highest energy.
What is the difference between computer glasses and blue light glasses?
Blue light-blocking glasses are considered a type of computer glasses. Blue light glasses are only designed to block out and reduce the possible harm of extended blue light exposure. They have lenses with a special lens add-on or tinted glass designed to reflect or block blue light from reaching your eyes.
Generally, the best computer glasses will feature some kind of blue light filter. Depending on the wearer’s use and needs, they may include an anti-glare coating or multifocal or prescription lens.
Do you need a prescription for computer glasses?
Most computer glasses do not require a prescription if they only feature anti-reflective coatings or blue light filters. If you require computer reading glasses or computer multifocal lenses, you will need an eye exam and up-to-date prescription from your optometrist.
Regular eyeglasses and computer glasses are different. As mentioned, computer glasses are only designed to reduce and relieve digital eye strain. They may have an anti-reflective coating, filter blue light, or include multifocal lenses designed for computer use.
For those who wear glasses, Vision Direct offers the option to add blue light-blocking tints or anti-glare coatings directly to your prescription lenses, giving you both clear vision and the benefits of computer glasses.
Are computer glasses worth it?
While computer glasses effectively reduce the amount of harmful blue light and reflections that enter the eyes, there is no research to suggest that they can improve or protect your eye health.
But, if you spend a lot of time on your computer or smartphone, they are a great aid in reducing glare and digital eye strain.
Should I be using computer glasses?
Computer glasses, including blue light glasses, anti-glare coatings, or computer multifocal or reading glasses, may help to reduce digital eye strain. If you’re experiencing eye strain, it may benefit you to invest in a pair.
Eye health should always be a priority. If you want to learn more about computer glasses or have any questions, head to our Optical Centre to speak with one of our in-house opticians.
