Glasses are glasses are glasses, right? Well, not exactly. When it comes to computer glasses and readers, there are some pretty significant differences. It may be a little tough sometimes to figure out which you need at a given time. This brief guide will help you better understand your eyeglass options as well as when you need computer glasses or when readers might be a better option.
Computer Glasses: Reduce eye strain and lessen screen glare
If you spend any amount of time working on a computer to doing things on your electronic devices like a tablet or smartphone, you may find that your eyes get tired or blurry after a while. This is because the light that comes from these screens makes your eyes work harder to see contrast. This light is often called “blue light” and it can be very hard on your eyes. In fact, experts recommend giving your eyes a break ever so often, such as using the 20-20-20 Rule or just walking away for a while.
People who are sensitive to light are usually more susceptible, but even people who don’t have any problem with light sensitivity will feel the effects after prolonged use. This can lead to migraine, headache, watery eyes, and other discomforts.
Computer glasses have a special anti-reflective coating or tint that blocks the blue light, lessening the strain on your eyes. They can be prescription or non-prescription. Many types have a special tinting that cuts the glare while increasing the contrast. These precision tinted lenses can help prevent headaches and migraine associated with computer use.
Readers: Bringing small print into full focus
If you read print books and find that you have difficulty focusing or your eyes get tired quickly, then readers may be what you need. While computer glasses deal with the glare of the screen, all reading glasses do is magnify the print so your eyes don’t have to work so hard to read it. Eye strain can cause your eyes to be itchy and watery. It can even lead to migraine or headaches.
Reading glasses can be a prescription, especially if you have an astigmatism or other issue with your eyes, but there are also the over the counter magnification glasses. Those work just fine for most people. The lenses are categorized by several magnification strengths. You just have to find which is best for you. These lenses do not have any type of coating though, so they don’t protect your eyes from the unique glare of a computer screen. If you purchase prescription reading glasses, you can often get an anti-reflective coating for the computer and even one that darkens automatically when they are exposed to bright lights.
Computer Glasses vs Reading Glasses
Computer glasses are not recommended for reading and reading glasses are not usually recommended for using a computer. This is mainly because your computer screen is several inches away from your eyes, while a book is usually much closer. Add to that the blue light emitted by the computer screen and you have two environments that are quite different and using the glasses in ways they weren’t meant to be used can lead to eye strain.
Choosing prescription glasses with blueblocking tint will make your experience on the computer much more enjoyable while readers can reduce eye strain when you are reading books or physical documents. If you have light sensitivity, glasses with tinted prescription lenses like Axon Optics’ migraine glasses can help. They may also double as readers or computer glasses.
An eye exam is typically the first step in determining what type of glasses you need. It will identify any problems you may have with your eyes, plus it will ensure that you get the exact magnification that you need.
Lenses vs Lens Treatments
When it comes to how your glasses to perform, the lenses are what makes the difference. Both computer glasses and readers have lenses that are carefully crafted to carry out a specific function.
Vision correcting lenses are often prescription lenses, although many reading glasses do not require a prescription. Bifocals, progressives, and no-line bifocals fall in this category as well and it is possible to get them with readers on the bottom portion of the lense. Computer glasses can be vision correcting with your regular prescription, with a graded magnification, or with no vision correction at all.
Tinting is a process that is applied to lenses. Whether you are getting tinted lens treatment for light sensitivity and migraine or blueblockers for computer lens treatment, they are applied to the lenses and are appropriate for prescription, magnification, or plain lens.
Axon Optics’ precision tinted lenses for light sensitivity and migraine are not the same as the blueblocking lenses in computer glasses. Blueblockers are for anyone who may experience eye strain after looking at LED screens on tablets, smartphones, and other electronic devices.
The precision tinted lenses from Axon Optics are actually more effective than standard blueblocking computer glasses because they block more blue light. This may be at least part of the reason that they are so effective for treating light sensitivity and migraine. There are several studies that support this tint’s ability to help with light sensitivity as well as blocking blue light.
People who have light sensitivity or who have migraines that are triggered by light will likely get relief with Axon Optics’ lenses and they can enjoy the extra benefits of the glasses blocking blue light. People who are not light sensitive will probably find that a classic bluelight blocker works just fine for them.
What You Need to Know about Bluelight and Blueblocking Lenses
What is Blue Light?
Once upon a time, before computers and electronic devices, people were only exposed to blue light when they were out in the sun. As technology has become more and more integrated into our lives with smartphones, tablets, computers, and other devices, blue light exposure has increased exponentially. The best way to minimize exposure is to minimize time on devices, but that isn’t likely to happen. Incidentally, blue light is also the reason that many people have trouble falling asleep after being on their computer or smartphone. It tricks the brain into thinking it is daytime.
What are the Effects of Blue LIght Exposure?
There are three areas where long term, consistent blue light exposure has a significant impact.
Eye Strain and Fatigue – The Vision Council’s Digital Eye Strain Report, published in 2016, showed that more than 34% of adults experience eye strain due to digital device use. The connection between eye strain and blue light lies in how the light behaves and how the eyes react to it. When bluelight passes through the lens of the eye, it moves across the front of the retina in a spray or scatter pattern, creating a glare or chromatic effect. The eye has to work a lot harder to process light in this pattern, and the longer it is exposed, the harder it has to work and the more fatigued and strained it gets.
Visual Impairment – Bluelight is different from UV light. Bluelight moves through the eye all the way to the retina while UV light does not. When this happens, there is a photo-oxidative reaction that affects the retina cells that begins the moment the blue light hits them. This can lead to an accumulation of toxins which can lead to impaired vision.
Sleep Problems – In a human’s most natural state, their sleep/wake cycle is regulated by sunlight. In fact, it is the blue light that is naturally occurring in sunlight that triggers a chemical process that halts the secretion of melatonin and signals the body that it is time to wake up. Melatonin is what signals the body to get ready to go to sleep. When a person is on their electronic device, the bluelight that is emitted from the screen tricks the brain into believing that it is daytime which means it does not produce melatonin. This can lead to sleep problems and poor quality sleep.
How can computer glasses help?
The special coating on the lenses of computer glasses will either deflect the bluelight or absorb it. Lenses that deflect the bluelight are tinted and may appear purple or blue. They do just what the name implies, they act as a barrier between the eye and the source of the bluelight, deflecting it. Lenses that absorb the bluelight are usually yellow. They also act as a barrier between the source of the light and the eye.
