Anti-glare eyeglasses are a great solution for people who need to read or work on their computer screen for long periods of time. In order to properly protect the eyes, a person needs an anti-glare lens, also called an anti-reflective lens.
There are two types: polycarbonate and carbon-aluminate. Both types have anti-glare properties but the carbon-aluminate is believed to be more effective. Carbon-aluminate glasses can reduce the glare by as much as 90 percent. It also reduces the scattering effect that occurs during daylight.
Anti-glare is important in driving because it allows the eyes to focus. This leads to a decrease in eye contact time, which increases driver safety. When the eyes are not focused on objects, the driver’s alertness is diminished and there is a greater risk of an accident or crash.
Research has shown that when objects are illuminated at their center, rather than their edges, drivers spend longer periods of time processing the information and making judgments about the scene. This type of visual input allows the eyes to concentrate without straining. Go ahead and see this guide on purchasing anti glare glasses to know more.
Anti-glare glasses reduce the glare from both the front and the back of the eye. Many drivers encounter the problem of glare without realizing it. The problem usually occurs with night driving where there is a bright light behind you, such as the sunlight on a street corner.
A driver can minimize the effects of glare by adjusting his or her vision. An experienced driver can often see the reflection of objects hundreds of yards away, but at night, the effect is not as noticeable because of the low light.
One type of anti-glare lens has been around for decades, the carbon-aluminate coating. Carbon-aluminate has increased refractive strength, which improves image clarity. Carbon-aluminate is made up of several compounds, including naphthalene, trihalomethane, and methylbenzene.
The compound has an improved reflectivity, which is what makes carbon-aluminate so effective. In addition to anti-glare function, carbon-aluminate is also approved for use in improving color quality. Non-carbon-based anti-glare glasses have many similar properties.
They reduce glare and can even improve color quality by neutralizing certain reflected colors. Many manufacturers make non-carbon lenses, so they do not alter the color of your eyes when they pass through them. In addition, these lenses are available in disposable form.
These lenses are often used in driving schools because they do not leave marks on the surface of the eye and do not cause much discomfort. Some manufacturers coat lenses with anti-reflective materials that also change color as they accumulate physical charge, such as when a lens is exposed to UV light.
This change in color is called an “anti-reflective coating.” Though coatings can be good for some types of glasses, others can interfere with certain computer applications, such as screensavers. Some anti-glare coatings do not meet federal guidelines for safety, because they may contain substances that could affect the brain’s ability to focus.
The other type of coating is made to reduce the number of reflections that reach the eye, instead of having no reflection at all. This type of coating does not alter the color of the eyes, so it can be used in any normal glasses or contact lenses.
The most popular types of anti-glare reflectors are made from polycarbonate and CR-39 plastic. Both are safe, but polycarbonate has the most significant advantage: it reflects everything except extremely bright light.
Thus, it eliminates the need for glasses to protect the eyes from UV rays or other light reflections. CR-39 plastic has similar properties. Even though there are many pros and cons to anti-glare, they are still preferred by a majority of people.
They are affordable, provide superior vision quality, and don’t require prescription glasses. You can find good prices on anti-glare and anti-reflective colored contacts online, and you can even customize your prescription lens if you so choose.
It is always recommended to consult a doctor if you have vision problems, and ask him or her to recommend a good pair of corrective lenses. There are many manufacturers of prescription eyeglasses, including brands like Oakley, RayBan, Spy, Oakley-owned Voigt, and Creative Optics.
