Whether you use your mobile phone, watch TV, or the computer Screen, you can experience exposure to harmful blue light rays. The good news is that there are ways to combat this, 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 the retina.
Some of the potential risks associated with blue light exposure include:
- Eye strain and fatigue
- Headaches
- Blurred vision
- Sleep disturbances
- Macular degeneration
How Do Blue Light Blocking Glasses Work?
Blue light-blocking glasses are designed to filter out or reduce the amount of blue light that reaches your eyes. They typically feature a special coating on the lenses that either absorbs or reflects blue light. These glasses come in various types, including prescription and non-prescription options.
What are the benefits of blue light and the negatives?
While blue light waves can be very 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, damage to the retina, difficulty sleeping, headache, or accelerated presbyopia.
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.
