Eye-Point Technology™

Eye-Point Technology™ simulates the human eye in every angle, prescription, and field of vision.

These techniques enable Shamir to create a sophisticated progressive lens surface based upon thousands of points of data. It’s this “design inside” that makes Shamir progressive lenses the most advanced in the world. Eye-Point Technology™ can simulate exactly how the human eye will see through the lens and then calculate the optical performance of thousands of locations covering the lens surface, taking into account the following parameters:

• Lens index refraction
• Lens prescription
• Lens center thickness
• Distance from the eye to the back vertex of the lens
• Distance from the lens to the object
• Pantoscopic tilt of the frame
• Pupil distance
• Thickness reduction prism
• Angular position of the object in the eye’s field of vision
