Have you ever heard your mom saying not to sit close to TV screen because it could hurt your eyes? You might not have paid attention then, but she was right. Every person in this modern age is connected. Kids between the ages of 8-18 years spend 7 to 8 hours in front of the screen. When talking about the modern workplaces, nothing is done without computers. Not to forget the screens at your home.
Do your eyes feel tired and hurt after this exposure to digital screens? Extended hours in front of the screen can cause vision issues such as Computer or PC Vision Syndrome.
According to the AOA (American Optometric Association):
“People having too much screen time can have blurred vision, headaches, eye strain, dry eyes, shoulder and neck pain.”
Are you looking for something that can help? Here is the deal. Fortunately, we are living in the age where there is a solution to every problem. Computer eyewear can help you prevent digital eye strain. With computer glasses on, digital screens become safe for your eyes. Read on to know how these glasses can be helpful.
What are Computer Glasses?
There are many factors that result in eye strain such as prolonged use of digital devices with screens just a few inches near your eyes. Moreover, there is an emission of blue light from screens that makes it difficult for your eyes to focus. You would have to refocus to keep working. To prevent your eye from getting hurt, computer glasses have been designed.
You are probably wondering: “What is so special about these glasses?”.
This pair of glasses filters out those blue lights releasing from your computer screens. Theis specially-coated eyewear is designed in a way which aids your vision when you’re glaring at the screen.
How Do Computer Glasses Work?
These are special-purpose eyeglasses which claim to optimize your vision when you spend long hours near digital screens. It helps to reduce the major causes of eye strain. They ease glare, enhance contrast, and maximize images. You can spend extended hours without hazards by seeing through these lenses.
Two main features of these glasses are anti-reflecting coating and color tint.
1. AR or Anti-Reflective Coating
This is a coating on the outer side of the lens, which reduces glare coming from the screen and other ambient light sources. The manufacturers like Gunner and VC offer this coating in gaming and PC glasses. You must be thinking, what if you already wear prescription glasses?
Good news is, anti-reflective coatings can be put on your prescription glasses as well. What could be better than this?
Nevertheless, not all these anti-reflecting coatings provide effective results. It depends on the quality. A cheap coating claiming to be the perfect one isn’t a good deal. It may look attractive but do not play fool here. They can even worsen the vision.
These coatings have come a long way over these years. Thus, you would find both new and old ones. Newer ones are more advanced and work better. Computer vision consultants emphasize on the latest coating. So, always ask for the latest one.
Dr. Paula Gorlin, member of the American Optometric Association tells the difference between coatings as:
“Some coatings are dipped onto the lenses, you can even peel them off. On the other hand, some are baked or ionized into the lens matrix.”
She recommends Crizal Sapphire UV AR coating to her patients.
2. Color Tints
Some glasses eyewear come with a yellow tint. It is designed to enhance the contrast on the screen of your phone or laptop. Furthermore, it keeps your eyes from the harsh light spectrum. It also relaxes your muscles.
Do you want to have tint other than yellow? Yellow glasses are signatures of some brand nut you can get other colors as well. Also, the tint can be applied to other glasses.
Lens Designs For Computer Glasses
The lens used in computer eyewear is particularly designed to work well near a computer. Also, these lenses are only prescribed for digital screens and you cannot wear then for general purpose.
There are three types of lens used in computer glasses:
- Single vision lenses
- Occupational progressive lenses
- Occupational bifocal and trifocal lenses
Single Vision Lenses
A simple computer glasses pair features single vision lenses with modified lens power. It enables the person having a comfortable vision.
It gives the largest field of view makes it easy to focus. Single vision computer glasses aids in getting rid of eye strain, blurred vision and unnatural poses that result in neck and back pains.
Occupational Progressive Lenses
Some computer glasses offer occupational progressive lenses, which correct near distance vision and provide more comfortable vision on the computer. These lenses are not suitable for distance vision tasks such as driving.
Occupational Bifocal And Trifocal Lenses
These lenses cover larger zones for intermediate and near image that you can customize according to the needs.
Consult your optometrist before you choose any of the above lenses.
Main Advantages of Using Computer Glasses
Some people are just fine with eye strains. They embrace them and do not bother to do anything about that. This is not a wise idea, at least not recommended by an eye doctor.
Here is how glasses can make your eyes feel better:
- Eyeglasses keep the blue light emitting from your computer away from your eyes which is the main cause of eye strain.
- Those eyeglasses with high-quality anti-reflective coating give a clear vision and keep the dust and fingerprints from appearing on the lenses.
- Some computer eyewear comes with a small bump that makes the print on screen look larger. It is a good way to reduce eye strain.
- Computer glasses increase contrast so that it is easy for you to focus on the screen.
1. Fewer Headaches
It is easier to focus when you see an object close to your face. We see the clear and sharp image when eye’s muscles adjust the curve of the lens in your eyes. When the object is 4-10 inch away, the muscles contract easily. Your eyes don’t have to struggle to focus.
On the other hand, when we talk about the objects farther away, the eye muscles relax and let you look at the distant image without strain. It allows adults to see the object clearly at the distance of 31.5 inches.
When we sit in front of computer screens, the distance from your eyes is usually 15-20 inches. At this distance, the eye needs to focus and refocus constantly to see the screen clearly. This struggle of your eyes results and headache and migraines. Even the individuals with 20/20 vision can have this type of complaints.
When you have your computer glasses on, you can focus on the image on screen without strain. These glasses have a multifocal lens which makes the computer screens look like reading paper. You wouldn’t have to stare.
2. Improved Posture
Do not mix the reading glasses with computer glasses. Reading glasses let you see the close objects while computer glasses are for up-close distances i.e. a few inches from your face.
Your computer screens are likely to sit at the point where you have to move closer or lean forward in order to get the clear image. You have to set yourself in an unnatural posture. Adopting these positions can cause tension in your neck and shoulder. Moreover, it can bend your spine which has to be attended immediately.
With computer glasses on, you wouldn’t have adopted different positions to focus on the screen.
3. Increased Productivity
Can you keep on working for unlimited hours with light bouncing off your screens and causing your eyes hurt? You need frequent breaks to give your eyes some rest. Headaches and back pain also take over when you don’t take rest.
Anti-reflecting coating and tint of computer glasses reduce the reflection on your lenses and eliminate strain. Most doctors recommend yellow tint as it lessens the effect of blue light releasing from the computer.
