What is blue light? How does it affect your eyes?
The three primary colors in light are red, green and blue. More colors include orange, yellow, violet and indigo. All of these colors mix together to make white light, as is seen with the sun shining. The sun itself is a source of blue light.
Light bulbs such as LEDs (light-emitting diodes) and fluorescents emit blue light, too. Another fascinating element of light is that each color has a distinctive wavelength and energy. Blue light is short in wavelength and has higher energy than the other colors.
There is research that demonstrates a connection between shortwave blue light and eye damage. Short blue wavelengths are emitted in the light from smartphones, TVs, tablets, and computer screens.
Looking at the sun’s high-energy ultraviolet rays increases the risk of eye damage and disease. Similarly, blue light given off by electronic devices is damaging to the eyes, too. It is estimated that one out of every two computer users experiences eyestrain or computer vision syndrome. This can, in turn, lead to dry, irritated eyes or blurry eyesight.
Blue light exposure is on the rise
Blue light is part of the visible light spectrum. Sunlight is everywhere, and the use of digital devices has increased. Both of these energy sources are readily accessible.
Optometrists estimate that 60% of people use their digital devices at least six hours a day. Approximately 80% check their smartphones within 15 minutes of getting up in the morning. People tend to not blink as much while using their digital screens, continually exposing their eyes to the bright white light LEDs that are lighting up their displays.
There is cumulative exposure to screen time throughout the day at work, at school, and during entertainment and play. Adults now spend up to half the day on digital devices. Children have doubled their screen use time. Nearly all blue light reaches the back of the retina. This may accelerate age-related macular degeneration, or AMD.
Do you need protection from blue light exposure?
All people who are exposed to blue light need to take precautions and protect their eyes. Today’s electronic device environment exposes people of all ages to high levels of blue light. Given the knowledge of its effect, the majority of people would do something about it and take precautions. Yet most people have not talked to their doctors about it.
Yet with all the exposure to blue light, the macula region of the eye becomes the most vulnerable target. This can result in eyestrain and dry eye.
Signs & Symptoms
- Eye fatigue
- Sleep disruption
- Retinal cell damage
- Cumulative damage resulting in age-related vision loss, such as AMD
If you have been experiencing any of these symptoms, a visit to your eye doctor is a positive step toward restoring good health to your eyes. A comprehensive eye exam by your eye doctor will assess your current eye health and evaluate any risk factors. With a diagnosis, your doctor can formulate a treatment plan to manage a healthy outcome.
Focus Blue Light contains Lutemax 2020 which is clinically proven to support eye health and protect against the damaging effects of blue light. It assists ocular performance, photo stress recovery, and disability glare levels.
The B.L.U.E. Study was the first human clinical trial to study the effects of supplementation in healthy, young people. The subjects had macular carotenoids during extended blue light contact with digital devices. The subjects in the study benefited from Lutemax 2020 supplementation and had a notable improvement in the areas of contrast sensitivity, disability glare, headache, eyestrain, eye fatigue, macular pigment optical density, neck strain, photo stress recovery, and sleep quality.
