You can experience exposure to harmful blue light rays through your computer or phone screens, or out in the sun. The good news is that there are ways to combat this and protect your eyes and avoid vision problems down the road. Blue light filtering glasses and zFORT blue light blockers are some ways to help combat this issue, especially if you spend a lot of time at the computer. 

What is blue light? 

Sunlight is made up of red, orange, yellow, green and blue light rays with different levels of energy and wavelengths. Blue light rays have short wavelengths between 380nm and 500nm with high energy levels. Studies have found that when blue light rays reach a wavelength of between 415-455nm, they could be extremely harmful to eye health as they penetrate through to the retina. 

What are the benefits of blue light and the negatives? 

While blue light waves can be harmful to your eye health, they aren’t all negative. Some blue light exposure is necessary for improving your memory and mood, regulating your sleep cycle, and maintaining healthy eye development for children. 

On the other hand, excessive exposure to blue light could pose a threat to your overall health, including the possibility of causing digital eye strain or damage to the retina. 

What’s zFORT™ ? 

zFORT™ blue light block technology was recently launched at SmartBuyGlasses. 

This technology can block a portion of blue light wavelengths between 380 and 500nm from reaching your eye and damaging your eye health. 

The chances are that you spend enough time in front of a screen to be benefitted by blue light blocking glasses. With zFORT™, you can turn any regular pair of glasses into computer glasses for good vision as well as good eye health. 

The main reasons we’re buying zFORT (and think you should too):

  1. Potentially less glare when working/gaming/looking at your computer screen
  2. Help to reduce eye strain
  3. Help to improve sleep
