What is Blue Light?
Blue light is a colour in the “visible light
spectrum” that can be seen by the human eye. Blue light has a very short wavelength, and produces a higher amount of energy. Studies suggest that over time, exposure to the blue end of the light spectrum could cause serious long-term damage to your eyes.
Sources of blue light include the sun, digital screens (TVs, computers, laptops, smart phones and tablets), electronic devices, and fluorescent and LED lighting.
What damage can it cause?
Exposure to blue light can cause eyestrain, headaches, physical and mental fatigue caused by many hours sitting in front of a computer screen or other electronic device.
Our eyes’ natural filters do not provide sufficient protection against blue light rays from the sun, let alone the blue light emanating from electronic devices or fluorescent-light tubes. Prolonged exposure to blue light may cause retinal damage and contribute to age-related macular degeneration, which can lead to loss of vision.
Chronic exposure to blue light at night can lower the production of melatonin, the hormone that regulates sleep, and disrupt your circadian rhythm.
How can blue light lenses help?
The use of protective eyewear can help shield your eyes from the harmful effects of blue light. We have special blue light filter coated lenses that cut the harmful portion of blue light, while allowing the good portion of blue light to pass through.
