When you use a computer, smartphone, or any other digital device for some time, you might notice experiencing eye heaviness or soreness afterward. This is computer vision syndrome or digital eye strain. Here’s what your optometrist has to say about this problem and how using blue light-blocking glasses can work to manage it:
What Causes Digital Eye Strain
A lot of factors contribute to the development of digital eye strain. It could be your bad posture, poor lighting, or a screen that’s too bright. Many studies also show that exposure to blue light rays, which are emitted by digital devices, is another factor. Experts say that blue light radiates high energy levels that may be too much for your eyes to handle. As a result, your eyes feel tired after being exposed to blue rays for an extended period.
Why Use Blue Light-Blocking Glasses
Because of these findings about blue light from digital devices, using computer eyeglasses has become increasingly popular over the years. Your optometrist explains that lenses of computer eyeglasses are specially engineered to block blue light. This way, your eyes won’t be exposed to as much blue rays as before.
In addition, computer eyeglasses are designed to optimize your eyesight when viewing a digital screen. They are usually equipped with around 60 percent magnifying power, which is beneficial when reading text and viewing monitors. Computer lenses can be used for both prescription and non-prescription glasses as well. Also, they focus optimum lens power right where you need it so you can have a clear, wide field of vision without having to exert more effort.
Other Ways to Prevent Computer Vision Syndrome
Apart from using computer eyeglasses, observing the 20-20-20 rule can also help you avoid having computer vision syndrome. This means that for every 20 minutes you’ve spent using a digital device, you have to rest your eyes for 20 seconds by looking at an object 20 feet away from you. Your optometrist also wants you to use ergonomic chairs so you can sit properly in front of your computer. You should adjust the monitor’s brightness to match that of your surroundings too.
