Blocking Blue Light


Suwanee’s Advanced Family Eye Care offers technologically advanced diagnostic and treatment alternatives to maximize one’s vision and eye health care. A current hot topic in eye care is blue light — blue-violet rays of the visual light spectrum that are present in sunlight and all back-lit devices, including computers, digital game and smartphone screens, tablets and televisions. While it’s hard to escape these screens in today’s technology-dependent world, there are ways to protect yourself from damaging blue light.

new threat to eye health is emerging as we spend more time connected to devices. Blue-violet rays of the visual light spectrum, known as “blue light,” are present in sunlight and all back-lit devices (computer, digital game and smartphone screens, tablets and televisions). Blue light rays cause damage as they penetrate deeper into the tissue of the eye, specifically the center of the retina, known as the macula. Over time, damage from blue light can lead to the onset of age-related macular degeneration (AMD). One of the leading causes of vision loss in those over 50, AMD affects central vision and can increase in severity over time.

Just as previous generations developed tools to protect against UV light damage, lens manufacturers, including industry leader Essilor, have developed several options to protect eyes from damaging blue light. Transition lenses are lenses that change from clear to tinted in sunlight. These lenses filter blue light both when clear and activated. Transitions are now available in seven different colors and several styles.

Reducing Blue Light
Eyezen lenses are a newer technology that filter out blue light and help to reduce eye fatigue and strain when used for computer work. These lenses are great for those of any age because they are digitally designed and provide excellent clarity and protection.

Crizal Prevencia is an anti-glare treatment that also reduces blue light. It is an ideal option for glasses that will be used on digital devices because the glare reduction and blue light filtration combined lead to a very comfortable experience.

Although they have not yet officially launched, Johnson & Johnson has developed a new Transition contact lens, Acuvue Oasys with Transitions, that should launch in 2019. These lenses will block 100% of UVB rays and filter out blue light as well—the first contact lens to do so.
