No. Blokz™ blue blocker lenses are made with a special blue-light blocking polymer from Mitsui Chemicals, a leading lens material manufacturer, that is directly incorporated into the lens materials. That means the blue- blocking technology won't chip or wear away. By absorbing blue light, this polymer prevents blue light from passing through the lens to your eye.
WHAT DOES “VIRTUALLY CLEAR” MEAN?
Unlike typical blue blocker lenses which have a very noticeable yellow or orange tint, Blokz™ lenses are one of the clearest blue-light-blocking lenses on the market, with only a slight tint. However, some customers with a moderate to high prescription strength may notice a mild yellow tint as the lenses become noticeably thicker.
Yes. Blokz™ (regular and tinted) comes with a standard anti-reflective coating, and Blokz™ Trivex® and Blokz™ Photochromic come with a super hydrophobic anti-reflective coating.
CAN I ORDER PROGRESSIVE OR BIFOCAL GLASSES WITH BLOKZ™?
You can order progressive Blokz™ blue blocker lenses but not bifocals.
SHOULD MY CHILD WEAR THE BLOKZ™ LENS?
Yes! Children are especially vulnerable to the effects of blue light because their eyes have not yet developed natural defenses against UV and blue light. Now that smartphones, computers, and tablets are a regular part of kids' lives, they need blue protection more than ever. We recommend Blokz™ Trivex® lenses for children due to their impact-resistant properties. Trivex® is a registered trademark of PPG Industries Ohio, Inc.
