Now you can have ordinary vision or high-definition vision. The optical system of the eye is imperfect. Distortions can cause problems with glare, haloes, and loss of contrast … especially at night. Our new zView abberometer can quickly and accurately measure the distortions unique to your optical system and a custom lens can be created to give you the best and clearest vision possible today. The lenses are now available as progressive bifocal and/or sunglasses lenses as well.
