UV Protection
The UV rays in sunlight can be harmful to the eyes.
Lenses that block 100% UVA and UVB help to ward off the damaging effects of UV radiation.
Photochromic lenses and most quality sunglasses offer UV protection.
Scratch-Resistance
Scratches on lenses are distracting,
unsightly and in certain conditions even potentially dangerous.
They can also interfere with the desired performance of your lenses.
Scratch-resistant treatments toughen up the lenses making them more durable.
The Differences Between 1.50 and 1.56 Lenses?
The difference between 1.56 mid-index and 1.50 standard lenses is thinness.
Lenses with this index reduce lens thickness by 15 percent.
Full-rim eyewear frames/glasses worn during sports activities are most suitable for this lens index.
Aspheric lens advantages
Generally speaking, the spherical lens is thicker; the imaging through the spherical lens will deform.
The aspheric lens, is thinner and lighter, and make a more natural and realistic image.
Anti-reflective Treatments(AR)
For fashion, comfort and clarity, anti-reflective treatments are the way to go.
They make the lens nearly invisible, and help cut glare from headlights, computer screens and harsh lighting.
AR can enhance the performance and appearance of just about any lenses!
