Anti-glare (AG) glasses are eyeglass lenses fused with an anti-reflective coating to prevent glare from either side of the lens. They enhance comfort, reduce eye strain, and improve the cosmetic appearance of glasses.
Although anti-glare eyeglasses offer minimal protection against these harmful rays, they can be enhanced with UV protective features such as polarization or photochromic technology.
Your lifestyle may also dictate the kind of anti-glare coating that's best for you. If you spend most of your time on a TV or computer screen, your eye doctor will recommend blue light blocking lenses, such as Crizal Prevencia or Shamir Glacier Plus.
AG lenses have an anti-reflective coating that prevents back glare, allowing the full spectrum of visible light to pass through. This includes a significant amount of blue light, which is considered harmful to vision.
The most obvious benefit of anti glare glasses (also called anti-reflective lenses) are that they reduce glare from all light sources and give much more comfortable vision without the associated side effects of eyestrain and headaches in some cases. It allows you to work for longer and more productively when using digital devices such as computer screens and has a safety element when driving at night by reducing the sometimes debilitating glare of oncoming headlights
Anti glare glasses also results in sharper vision as it allows more light to be transmitted through the lens rather than getting reflected and the more light that gets through the sharper the vision and the contrast sensitivity and the better the visual performance.
Anti glare glasses contain lenses that have multiple thin layers embedded in it with each layer having a different refractive index (i.e. bending light by different amounts) These layers cause the wavelengths of the glare to neutralise each other and result in more light being transmitted through the lens with only a very small percentage being reflected. This neutralisation in the glare wavelengths result in a much more comfortable visual experience and a cosmetically pleasing hue from the lens rather than unsightly glare.
The best way to prevent glare is to use anti glare glasses if you are a glasses wearer, or non-prescription anti blue light lenses with anti glare, if you don't use prescription glasses but do use digital devices regularly.
Glare, along with blue light is a major cause of digital eye strain or computer vision syndrome. Glare from the computer screen causes the pupils to constrict and rapid eye movements which are highly correlative with glare discomfort. Repeated exposure to glare can cause a stress on the visual system causing eyestrain and tired eyes. Those with cataracts in their crystalline lens suffer even more from glare from computer screens because rather than doing through the lens unimpeded, light from the screen enters the lens and is reflected off the cataract causing more glare. When using digital devices using glasses with anti blue light lenses and anti glare lenses is a great idea to reduce digital eye strain and improve visual comfort.
The most important situation to use anti glare glasses is whilst driving, especially if driving at night. At night we are exposed to a number of light sources such as street lighting, headlights of cars and even the internal lights in the car itself. All these light sources can cause glare which can be dangerous if it distracts the driver and affects the drivers vision. At night time our pupils dilate to adapt to the low light levels. This means what when light is shone towards the eyes more light gets in and the eyes have to adapt quickly to the increased light levels. When we get older this reflex of constricting the pupil to incoming light slows down which increases the debilitating effect of the glare. Wearing tinted lenses when driving at night is not a good solution to protect from glare as it also decreases the overall amount of light entering the eyes which will reduce the sharpness of vision. Using anti glare glasses is a much better idea as it will reflect the oncoming light away from the eyes whilst maintaining the overall clarity of vision making driving at night much safer.
When you're working with a laptop or computer screen for much of your day, as many Australian employees do, you might notice that the brightness emitted by the machine can cause your eyes to feel strained. The symptoms of eye strain include blurred vision, tired or 'burning' eyes and a headache. If you are experiencing these signs, it's important to see your optometrist for a recommendation as to what may help ease and prevent the strain. In some cases, the solution can be as simple as adding an anti-reflective or anti-glare coating to your glasses.
Thanks to modern technology, today's anti-reflective coating can eliminate almost all reflection of light from the lenses of your glasses. This allows you to see clearly and without having to squint when it comes to using a laptop screen so your eyes are more comfortable. In addition to this, anti-reflective coatings can also help when you are driving at night. Many people who wear glasses tend to see a 'halo' effect around the headlights of oncoming cars in the darkness. This is distracting and can make it more difficult to drive, but an anti-glare layer on your glasses can combat this problem by eliminating the reflection from your lenses. The coating can make glasses more susceptible to becoming scratched or showing the marks left by oily fingerprints, so you will usually need to clean it with a special type of cloth. Some coatings come with an added 'hydrophobic' or 'oleophobic' surface that aids in preventing skin oils, smudges and water spots from lingering on the lens.
Anti-glare glasses can certainly help you work from your laptop screen more comfortably, but you can also protect your eyes by adjusting the screen so it's in a good position for your eye line. Remember to give your eyes a break every now and then by focusing on something in the distance.If you have any more questions about anti-glare coatings or what you can do, talk to a qualified optometrist.
These glasses have a tinted protective coating that limits the amount of blue light that reaches your eyes. They work in most settings with any blue-light emitting device. They're also called computer glasses, blue light blocking glasses, and blue light glasses.
Yes, anti-reflective coatings are one of the many options you can select for your blue light digital protection lenses. These useful glasses are also water-resistant and feature a hard coating for durability and longevity.
You may have considered buying a protective pair of glasses to wear when using your digital devices. But you probably took a step back when you came across all the confusing terms and different styles in the protective eyewear industry. What are computer glasses, blue light glasses, tinted glasses, anti-glare and blue cut What is blue light, green light and violet light Why do you need protection from different colours of light anyway What do manufacturers mean when they say their glasses protect you from different wavelengths
Computer glasses aka computer screen glasses are exactly what they read- glasses that protect your eyes from computer screens and digital devices. Nonetheless, how they do this and how effective they depend on the manufacturer.
There are glasses manufacturers who sell computer screen glasses that lack blue-light blocking characteristics but have other features such as anti-glare, slight magnification and de-centered pupillary distance. Still, these features come secondary to the protection offered by a blue light filter.
When buying glasses for computer use, having a blue light filter in your glasses is a must. Blue light-blocking glasses (also called blue-cut) are effective only when they provide some degree of protection against the entire spectrum of blue light.
Are most of your days (and sometimes, nights) spent at your laptop Whether your purpose is to finish up a work presentation or catch up on a new episode of a TV show, your eyes go through the same amount of exposure to blue light emitted by it. Fair warning, none of it is good. Since it's sometimes unavoidable and situations do require you to keep typing away, protect your eyes while doing so. Regardless if you have a prescription or not, anti-glare glasses can be worn to prevent its harmful effects and reduce squinting in front of screens. 59ce067264
