Eyeing New Technology For Computer Vision Syndrome

Eyeglasses or contact lenses prescribed for general use may not be adequate for computer work. Lenses prescribed to meet the unique visual demands of computer viewing may be needed. Special lens designs, lens powers, or coatings may help to maximize visual clarity and comfort. These lenses take into account the specific viewing distances of a computer screen and can be customized for most work environments.

Computer glasses are different from regular glasses because they are specifically designed to help reduce eye strain associated with computer work. Glasses designed for these devices use custom measurements and lens options to help avoid an unnatural posture that can result in neck and back pain. They are recommended for computer users of all ages.

They allow the eye to relax by reducing the amount of work required to keep the screen in focus. These lenses also provide the largest field of view, which may be ideal for those who use multiple monitors.

Multifocal computer glasses include occupational bifocal and trifocal lenses. These lined multifocal lenses have larger zones for intermediate and near vision than regular bifocals and trifocals,

The presence of even minor vision problems can significantly affect comfort and performance at a computer or while using other digital devices. Uncorrected vision problems can be major contributing factors to digital eye strain.

They are ideal for people who have a variety of tasks and visual demands throughout the day.

Modern light sources such as LED light bulbs, smartphones, televisions, computer monitors, and tablets all emit relatively high levels of blue light. Within the visible light spectrum, blue light has a shorter wavelength and higher energy, which can cause eye strain and potential damage to the retina. Studies have shown that this can increase your risk of macular degeneration.

More than half of adults spend at least six hours a day on phones, tablets, and computers. We use our electronic devices so often that we are gradually being exposed to more sources of blue light for longer periods of time. High quality anti-reflective coatings and blue light filters are encouraged in all lens types, but can be particularly helpful for those who spend multiple hours per day on digital devices. Pigments found within the eye also block blue light from being absorbed into the retina. The pigments come from the foods that we consume. Dark green leafy vegetables such as kale and spinach are especially high in blue light blocking pigments. Some eye doctors have the technology to estimate the amount of pigment in the retina, and if it is found to be low, diet modifications or starting on supplements can help to boost pigment levels.
