We use digital, or surfaced, lenses instead of standard stock lenses. Digital lenses are cut for each prescription. They cost more, but provide better clarity and minimal edge-to-edge distortion.
We use aspheric instead of spherical lenses. Aspheric lenses reduce magnification, so you don't get a fishbowl effect. They are thinner and lighter. And they provide better optical quality with less blur.
Product Description for Dilli Dalli Birthday Cake
Dilli Dalli eyewear, available from ClearVision Optical, is proud to present Red's Big Day, an animated depiction of the children's book of the same title. Red, one of the (bird) faces behind the Dilli Dalli collection, tries out for his school's flying team, when he finds out he needs glasses. It's a great story for little ones who are wary about wearing glasses. Glasses are cool!
