Ballo UV420 Blue Light Blocking lenses:
We live totally surrounded by screens, spending almost nine hours a day, on average, in front of digital devices.
All these devices emit blue light. Overexposure to blue light can strain eyes, affect sleep and result in headaches.
Our UV420 lenses offer 100% protection from blue light.

Technical information UV420 Blue light Blocking lenses
New Ballo CR39 UV 420 lens blocks 400-420nm of High Energy Visible (HEV) or "Blue" light in addition to UV-A and UV-B.
Blue light Background
Short-wavelength, high energy blue light scatters more easily than other light, which means that one cannot easily focus upon it. If you're looking at a computer screen, smartphone or other digital device that emits blue light, this unfocused visual light reduces contrast. This can result in the user straining his/her eyes.
Blue light is not all bad - in fact the human body needs it to regulate mood and aid in memory. However, the regularity of use and proximity of digital devices to the eye can result in too much exposure. Exposure to blue light at night, especially via digital devices, can result in (amongst other things) disturbed sleeping patterns.
Blue Light Radiation Sources
- The Sun
- Exposure and brightness outdoors (even on overcast days)
- Digital Devices including: Smartphones, tablets, computer screens
- Lighting
- LED & CFLs
Who Can Benefit
The shorter wavelength light of 400-420 nm, is more harmful for younger individuals under 20 years old, who spend a lot of time outside in sunlight, because their eye lenses are very transparent.
Individuals who spend a lot of time in front of digital devices can also benefit fit UV & HEV Light protection. Blocking UV and High Energy Visible (HEV) light is critical for protecting eyes against cataracts and age-related macular degeneration (AMD), a medical condition where the macula in the retina degenerates due to aging.
Technology
Standardized laboratory experiments show that neuronal retinal cells after exposure to short wavelength light of 411 nm begins to die from higher stress than after exposure to 470 nm light.
Clear Light Benefits
We are still exposed to 40-75% of Ultraviolet rays on cloudy days and 20-30% on rainy days. Clear lenses can be worn under all weather. You can wear clear lenses under all weather and always protect yourself from harmful light. The lenses do not affect the way we see natural colours thus the eyewear with UV420 is suitable of all occasions. Unlike other lenses that are significantly yellow, these are are slightly blue/grey.
