CR Surfacing Shaw Lenses
Traditional glasses lenses tend to provide accurate vision solely when looking through the optical centre of the glasses. However, as we go through our days, we’re required to look through all areas of our glasses, particularly when driving, reading, walking up the stairs and playing sports.
Off-centre viewing in traditional lenses results in distorted and blurred vision, different image sizes between the eyes and double vision. Moreover, traditional lens design makes one fundamental mistake: It doesn’t take into account the way both eyes work together. The result is glasses-induced distortion that can be as uncomfortable as uncorrected vision.
The SHAW™ lens uses a unique patented technology that minimises and even eliminates off-centre distortions while improving central vision by standardizing the image size in both eyes. SHAW lenses accommodate the way both eyes work together to solve for both dynamic and static aniseikonia. This dramatically reduces the distortion caused by other lenses.
With SHAW lenses, you’ll enjoy outstanding vision, reduced eye strain and fewer headaches.Kay Street Eyecare will perform the calculations and evaluate your eyes to check whether you can benefit from wearing the SHAW Lens. The SHAW Lens is available for single vision lenses, bifocal and multifocals, as well as prescription and photochromic sunglasses. SHAW lenses are manufactured with high index materials and are available in a wide variety of shapes and sizes.
Do you need single vision, bifocal, progressive or occupational lenses?
Shaw lenses are available in a wide range of lens styles and they are in a high index material that can include polarisation, tinting or transitions.
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 optimised 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.
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® lenses are all available.
Lens materialThe 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.
Frequently Asked Question About Prescription Glasses & Aniseikonia
Q. What is aniseikonia and why should anyone care?
A. There are two types of aniseikonia – static aniseikonia, in which the size of an image is different in each eye and dynamic aniseikonia, in which the eyes are forced to track vertically and laterally at different rates. The SHAW™ lens is designed specifically to solve aniseikonia.
Static aniseikonia commonly occurs as a result of eyeglasses being made to correct anisometropia (eyes have different prescriptions). Basically, what happens with traditional eyeglasses design is that the approach is monocular in nature. The assumption is that if one lens makes the left eye’s vision crystal clear and another lens makes the right eye’s vision crystal clear, then the patient will be able to sort it out. The problem is that when you solve for anisometropia (different prescriptions for each eye), a monocular approach induces aniseikonia and makes the image sizes different in each eye. This creates a whole different set of problems for the wearer.
Now the brain has to work to fuse these different-size images together. In dealing with the images that the glasses make, the brain may try to adapt by fighting to focus all the time or by suppressing the image from one eye, or it may not adapt and instead react with headaches, vision distortion or other problems and the patient just stops wearing the glasses for any length of time. Through our patented binocular optimization program, every SHAW lens is designed to effectively eliminate the difference in the size of images in each eye. This provides much better vision, depth perception and comfort in wearing glasses.
