Introducing a new addition to the
Viso® family of No-Glare lenses
Light can be both beneficial and harmful...
knows the difference
While light is beneficial for color perception and acuity,1 non-visible
light and visible light are risk factors for developing eye diseases1,2
•
Ultraviolet (UV) light is a risk factor for many severe
eye diseases, including cataract2,3
— 20 million cataract procedures are performed globally each year
•
Blue light (High Energy Visible light), at specific wavelengths, is a
risk factor for onset of age-related macular degeneration (AMD)
— AMD is the leading cause of severe vision loss and legal
blindness in adults aged 60 years or older1,2
The good and bad of blue light
Blue light is present every day, in all weather and light conditions.

The Good: Blue-Turquoise light (465 nm-495 nm) is beneficial for
vision and overall health. It aids various physical functions like the
sleep/wake cycle, memory, pupillary constriction reflex, and more
•
The Bad: Blue-Violet light (415 nm-455 nm) is the most harmful to
retinal cells,* and exposure may contribute to AMD
*Based on in vitro tests on porcine cells.
Help protect your patients with
No-Glare lenses
How does
WORK?
• Selectively filters out harmful Blue-Violet and UV light
• Enables beneficial visible light to pass through
These lenses optimize your patients’ vision by:
•
Deflecting 20% of harmful Blue-Violet light4
•
Providing 25x more protection from UV light than with no
lens at all (E-SPF® value of 25)
Now a broader range of benefits for
your patients than ever before
