SHAW Lens

Designing lenses that take into account how both eyes work together is not an easy task. The math is complex in a purely theoretically environment but when you factor in other variables like frame dimensions, the position of the glasses on an individual patient’s face and the limits that lens manufacturing and optics place, it’s no wonder why no one has done this before.
 

That’s what makes the SHAW lens unique. The SHAW lens process uses a patent-pending method to accurately model eye rotation in order to predict distortions caused by eye glasses. We then use that information to design a lens that reduces or eliminates the distortion other lenses can cause.
 

The key to making a SHAW lens is the measurement of Motor fusion (vergence) limits by the optometrist using Risley prisms on the phoroptor. It’s these tolerances that make all the difference.
 

Using the SHAW lens design software, the clinician has direct control over management of both refractive and binocular components. The exact effect on the vision system can be readily analyzed, and benefits of a SHAW design is graphically displayed before the lens is ordered.
 

Progressive Lenses

The SHAW PAL lens is a European design that gets modified using the SHAW lens algorithm to manage aniseikonia. Our PAL lens characteristics offer a wide viewing distance area and an optimized reading zone that the SHAW lens design software calculates automatically. Corridor length is specified to deliver a comfortable 23 ° of downward gaze for reading. This differs from the usual pre-set amount that may or may not work with the actual frame the patient chooses.

Single Vision Lenses

Even a small degree of aniseikonia can be problematic – even for people who don’t need progressive lenses. The SHAW lens can make a difference to moderate myopes, anisometropes, ambyopes and frames with a face form angle greater than five degrees.

Multifocal lenses

Let’s face it, not everyone likes progressive lenses. The SHAW lens is available for traditional bifocals as well, and offers the same solution for aniseikonia and other lens-induced distortions.

Coatings and tints

All of our lenses come with anti-reflection, hydro (water repellent) and oleo (oil repellent) coatings at no extra charge. Tints, polarization and Transitions® are all available.
 

Lens material

The SHAW lens is available in a wide range of lens materials, power range and corridor length that you’d expect a leading lens company to offer. But that’s where the similarity ends. With the SHAW lens system the practitioner doesn’t need to specify base curve, index, thickness or corridor length because the sophisticated SHAW lens software does that for each patient. It’s the simplest and most sure fire way to get the best vision for every patient.
