Why choose SaferOptics UV 420?

The effects of staring at screens are obvious. Tired and watery eyes, headaches, blurred vision, red eyes from too much rubbing. Blue light from computer screens and digital devices decrease contrast, leading to digital eye strain, fatigue, dry eyes and discomfort. Apart from these, prolonged blue light exposure can cause retinal damage to light-sensitive cells.

UV 420 high energy visible light spectrum

Blue light is a type of short wavelength light emitted at high energy from the sun, LEDs and digital screens. For the sake of long term eye health, we focus on the light up to 420 nm.

In the visible light spectrum, the shortest wavelength and highest energy light falls between 400 - 420nm. The light in this part of the spectrum is particularly harmful, as it can pass through the cornea and directly reach the retina. Prolonged exposure can damage light sensitive cells and cause greater oxidative stress.

Sources of blue light - mobile smartphones, tablet, laptop screen

While most adults check smartphones every 10 minutes, kids and teens also use these devices for entertainment, gaming and educational purposes. The more hours you’ll use your devices, the high amount of blue light rays will penetrate the eyes.

Children and younger individuals are at particular risk, because their eye lenses are especially transparent. So taking good care of eyes by filtering harmful blue light is beneficial from a young age.

SaferOptics block harmful blue light HEV

That is why we created our SaferOptics lenses to completely block this High Energy Visible Light (HEVL) using the latest UV 420 technology.

UV 420 blue light filter wavelength chart

1. Natural Colours - Even though UV 420 lenses filter higher range of blue light, it doesn't affect the colour of the lenses (NO yellowish tint) and does not change how colours appear.

2. SaferOptics Proprietary Anti-Glare Coating - reduces light scatterings and reflections, improving transmission for better contrast and clarity.

3. Smooth Easy-Clean Surface - Premium lens coating with Super Hydrophobic increases lens durability such as fingerprint smudges, liquid and scratch resistance.
