Ever felt dryness or irritation in your eyes because of staring at your screen for long hours at work? Digital eye strain is quite common among people who regularly use digital devices. According to the Vision Council of America, almost sixty percent of people have experienced CVS (Computer Vision Syndrome). Regular use of technology can pose risks to eye health. If you’re someone who suffers from digital eye strain, it’s time that you consider getting a nice pair of computer glasses. In the same vein, here are some of the key considerations when choosing eyewear to help alleviate CVS.
Blue Light Filter
It’s imperative to get a lens coating that filters out an excessive amount of blue light emitted from the screen of your smartphone or PC. As a result, you’ll experience less irritation & dryness in your eyes. If you’re someone who uses their phone a lot just before sleeping whether for reading e-books or browsing social media, blue light can reduce the amount of melatonin in your body thus resulting in lack of sleep. This can be mitigated by wearing computer glasses when using your phone at night.
For people who’re suffering from presbyopia (near sightedness) or astigmatism, it’s imperative that your eyewear provides the required level of vision correction by means of prescription lenses. Although computer eyeglasses have a reduced amount of magnifying power, you can still add the required level of vision correction lenses needed for you to see better, you can still add the right amount of power for your eyesight. Having said that, you should have an upgraded prescription of yours beforehand.
The most common lens type for computer eyeglasses is ‘single vision’. This is because single vision lenses offer the most comfortable view as compared to other types. They help lessen the symptoms of CVS such as dryness, irritation, headaches & sensitivity to light (photophobia). On the other hand, some people do choose progressive lenses, provided that they suffer from multiple refractive errors. By contrast, progressive lenses offer a vision-jump free vision with a one size fits all solution. However, they are not easy to get used initially which requires viewing through a limited lens surface as opposed to a single vision lens.
Some people also opt for photochromic lenses, this helps them enjoy outdoors as well as indoors with their glasses on without having to switch them with sunglasses. They also help enhance contrast to let you better able to view in broad daylight. However, you should always consult an optometrist before deciding on getting a pair of transition lenses.
When choosing glasses online, pay attention to how comfortable the given frame is for all-day wear. Your eyewear should offer an optimum view that enables a better posture, thus relieving neck pain & making you more productive. Typically, plastic frames are ideally suited for both reading & computer eyewear as they’re lightweight & are generally more comfortable to wear for long hours. You can even go for contemporary chic or hipster glasses that are considered cool by today’s digital natives.
If there’s one other lens add-on to go for in computer eyeglasses, it would be the AR or anti-reflective coating. It helps reduce glare by preventing reflections occurring at the back & front surface of your lens thus improving your vision. Furthremore, it also helps you see better in low light situations by allowing for a maximum amount of light transmission. On the whole, you can add both AR & blue light filter coating to experience the best of what computer eyeglasses could offer.
