What is Wave technology?
A “wave” of technology is common parlance for describing the wide-scale dispersal of new automation, mechanics or applied science. Technological waves are hard to predict yet often leave an indelible impact on a particular aspect of culture, industry and medicine.
What is Essilor wave technology?
Through W.A.V.E. Technology, Essilor has adapted the wavefront technology used in laser surgery to correct vision by detecting and even eliminating many surface distortions inherent in progressive lenses. Through W.A.V.E. Technology, Varilux Physio utilizes a front side design and digital surfacing on the molds.
Which protein is present in eye lens?
In anatomy, a crystallin is a water-soluble structural protein found in the lens and the cornea of the eye accounting for the transparency of the structure.
Which material is used in contact lenses?
|Material||Oxygen Permeability (Dk/t)||Modulus (MPa)|
How do you measure contact lenses?
Generally, your eye doctor will use a keratometer to measure the curve of your cornea, which is the front surface of the eyes – where contacts rest. These numbers help to determine the lens diameter and base curve that appear on your contact lenses prescription.
How do you test contacts?

Prescription Figures for Astigmatism Cylinder (CYL): The cylinder will always be a minus number that increases in measures of 0.25. Axis (AX): Astigmatism is caused by the irregular curvature of the eye; the axis is a figure which determines the angle of the correction needed in order to see clearly.
