Light scatters in all directions, but certain surfaces such as water and shiny places may intensely reflect light. This creates an annoying and dangerous intensity of light that you experience as glare. You can alleviate the effects of glare, enhancing the visibility of eyeglass wearers.
1. Purchase anti-reflective coated lenses. These lenses reduce both internal and external reflections on the lenses themselves. The lenses are coated with several layers of metal oxides applied to the front and back lens surfaces. Each layer is carefully placed to block reflected light so that you will see a reduction in glare.
2. Acquire polarized lenses. Polarized sunglasses prevent glare and haze so visibility is enhanced and your eyes are more comfortable. Polarized lenses contain a special filter that blocks intense reflected light, reducing glare. Use polarized lenses for indoor activities as well as outdoor activities such as skiing and fishing.
3. Choose progressive lenses especially if you are above the age of 40. Progressives protect you from the annoying light that reflects from the computer. They offer a smooth transition from focusing on nearby to distant objects, as they lack the line that separates the focusing powers. The gradual change in power allows you to focus on objects at all distances without distraction from the glare.
4. Seek an optician’s advice on photo chromatic lenses. These lenses react when exposed to UV light, darkening within minutes, or even seconds, allowing you to see comfortably. Photochromatic lenses are ideal as anti-glare because they serve as protection against UV rays, a known cause of cataracts. These types of lenses are equally effective for light sensitive people. They come in different shades with the most conventional ones being black and brown. Consider this type of lens if prescribed sunglasses or anti-reflective coated lenses are too costly for you.
Tips & Warnings
Always seek advice from an optician before purchasing or using eyeglasses.
Polarized lenses may reduce the visibility of images produced by liquid crystal displays (LCDs).
