Basically most digital devices have one thing in common: They all emit blue light, also known as high energy visible light.

Digital devices emitting blue light include:- 

  • Smartphones
  • Computer
  • Laptops
  • LED and LCD Televisions
  • Tablets and etc

Blue light is everywhere and can be found within the displays of smartphones, computers, laptops and tablet.

“Blue light is the most energetic portion of the visible light spectrum,” says ophthalmologist Bernard Godley, of the Retina Foundation of the Southwest in Dallas, US. Blue light wavelengths are range from 380 to 500 nanometers (nm). The band of blue light considered potentially most harmful to retinal cells ranges from 415 to 455 nm. Some of the most favoured digital devices use light-emitting diode (LED) light – backlight technology to enhance screen brightness. These LEDs emit strong blue light, typically in the wavelength starting at 400nm, which is very harmful to our vision.

Harmful effects of blue light exposure on our eye health

Basically most digital devices have one thing in common: they all emit blue light, a high-energy light which is very dangerous to our eyes. Blue light is everywhere and is always emitted from LED backlighting of smartphones, computers, laptops and tablets.

Cumulative and prolonged exposure to blue light can damage the retina, the light sensitive layer of tissue at the back of the eyes. The macula is a special area in the centre of the retina and responsible for clear central vision. Both retina and macula cannot be regenerated or be replaced if damage. Once damage has occurred, the eyes are left increasingly exposed to blue light, UV rays from sunlight and other harmful environment factors, increasing the risk for long-term visual impairment. Blue light leads to digital eye strain with symptoms such as blurry vision, dry eyes and etc.

Exposure to blue light can lead to age-related macular degeneration

Emerging research suggests that this cumulative and constant exposure to blue light can damage retinal cells and lead to age-related macular degeneration (AMD). AMD is the most common cause of visual impairment and blindness among the elderly.

The retina is the light-sensitive layer of tissue at the back of the inner eye. It can be harmed by high-energy visible radiation of blue light/ UV rays that penetrates the macular pigment found in the eye. The retina cannot regenerate or be replaced if damaged. Once damage has occurred, the eyes are left increasingly exposed to blue light and other harmful environment factors, increasing the risk for long-term visual impairment. According to a study by The Schepens Eye Institute, macular pigment in low density may represent a risk factor for AMD by permitting greater blue light damage.

Melanin as protection from harmful blue light and UV rays

Melanin is the pigment that gives human skin, hair, and eyes their color. Besides giving our eyes colour, melanin provides protection against harmful blue light and UV rays. It’s the body’s natural sunscreen protection.  However, once we age, we lose melanin. By age 65, about half of the protection is gone, making us more susceptible to eye disease such as macular degeneration.

Protect Your Eyes against Harmful Blue Light

It is important that you know how to protect your vision against the harmful effects of blue light exposure. Here are some tips to help you keeping your eye healthy.

1. Supplement with nutrients lutein and zeaxanthin

Zeaxanthin is highly concentrated in the macula, while lutein is more prominent in the retina. These 2 powerful eye nutrients provide antioxidant protection against harmful blue light from digital devices and ultraviolet light (UV) from sunrays. Lutein and zeaxanthin supplementation increases macular pigment density to help preserve vision.

2. Wear protective eye wear for indoors and outdoors

For indoor usage, lenses with amber/yellow filters which are customized to filter out harmful blue and violet light that is emitted by many digital devices are available. Besides that, high-energy visible filter that specifically designed to block out blue light, is a great option to reduce the adverse effects of excessive blue light exposure.

Sunglasses, which are specially tinted or polarized to absorb the UV rays and blue light rays, are perfect for outdoors.
