EYE GLASSES

Digital Free-Form  Lenses

Free-Form Digital lenses are the most important improvement in prescription eyewear in the last several years, greatly reducing distortion in most all applications. We highly recommend digital prescription lenses in most any frame and most any prescription, for most purposes. If you are ordering a large frame, have a higher prescription or using a wrap style or sports sunglasses, this digital design is even more important.

Our Free-Form Digital lenses use the newest and best digital design available today. Our lab has digital surfacing equipment and uses true Free Form input - these are both required to see all of the benefits of a digital lens.

In a Free-Form Digital lens, your prescription is recalculated at every point on the lens, then manufactured to a truly personalized prescription lens. This technology eliminates virtually all distortion, aberration, and the “Fishbowl Effect” – resulting in a clearer/sharper image and more “true to life”/natural vision.

SINGLE VISION LENS

The office setting is a good example of simultaneous visual tasks that most people typically encounter. The most popular method for correcting near vision is with a single-vision near lens correction. This lens provides clear near vision, with a large field of view. Although this corrective lens effectively clears the near vision, the disadvantage is that the distance objects are now blurry. You can also see that viewing an intermediate object, such as a computer screen, appears blurry as well. In order to clear the intermediate object you must move your head closer to the screen. This is because the near-vision correction is usually set for clear vision at around 16 inches. Computer monitors, like most intermediate tasks, are usually at a further distance. Using a single-vision near lens can be visually uncomfortable when multiple vision tasks are required. As a result, we need to talk about a more appropriate lens option.

BIFOCAL LENS

In order to maintain clear distance and near vision at the same time, bifocal lenses are the ideal solution. As you can see, bifocal lenses offer the advantage of clearing both distant and near objects. Although bifocals have a clear advantage over single vision lenses, they do have certain limitations. One major disadvantage of using a bifocal is the demarcation line which separates the distant and near prescription. This is a problem, because it creates a disruption when moving from the distance prescription to the near. Another complaint with bifocals is the optical phenomenon known as “jump” that is created when you move your eyes from the distance portion of the lens, through the demarcation line and into the near portion. This causes images to appear distorted, or displaced. Another limitation of the bifocal lens is the inability in most cases to view intermediate objects like a computer monitor. As you can see, while distant objects remain clear intermediate computer vision may remain blurry. If this is the case, the only way to clear the computer screen is to use the bifocal portion of the lens and you must move your head closer to the monitor. Constantly moving your head becomes very uncomfortable. Especially if computer work is performed for an extended period of time. The inability to clear the intermediate vision, is the major complaint by most bifocal users. And as a result, a different type of multi-focal lens is required.

PROGRESSIVE LENS

Progressive lenses provide a great solution for people who want to escape the limited correction that most lenses provide. As their name suggests, progressive lenses provide clearer vision not just for near and far, but also for all distances in between without any abrupt changes or visible lines in the lens. Progressive lenses are divided into three sections: distance, mid-range, and near. The distance portion of the lens allows you to clearly see anything that is more than a couple feet away, to as far as your eyes can see. The mid-range portion of the lens allows you to clearly see anything that is at an arm’s length, such as your computer screen or objects on your desk. The lowest part of the progressive lens, or the near portion, allows you to see up close and read with natural posture and a normal head position. For many lens wearers progressive lenses are a better alternative, offering outstanding clarity and comfort to see at all distances.

LENS COATING AND OPTIONS

ANTI-REFLECTIVE LENSES

Are you bothered by glare while driving at night? While there is no easy way to measure it, we all know glare when we see it. AR lenses are designed to eliminate glare. These lenses improve safety by allowing you to recognize potential hazards on the road, especially at night. As you can see the glare from headlights and street lamps are virtually eliminated. For more information ask about AR lenses.

COMPUTER VISION LENSES

Do you have tired or sore eyes? Headaches? Blurred vision? And general fatigue? If so, like millions of people, you may be suffering from a problem called Computer Vision Syndrome (CVS). CVS is the number one health complaint in the work place and affects everyone who works on a computer. Your computer screen projects images in tiny pixels. Although you are probably not conscience of it, these pixels constantly change, and your eyes must refocus with each change. This constant adjustment can strain your eyes. Your eyesight will start to become distorted or blurred. Your eyes may have difficulty focusing, in many cases; you may experience headaches, neck and back pain. There are ways to help CVS though. One of these ways is to wear a pair of computer glasses. These glasses reduce the glare on the computer screen, allowing your eyes to focus more easily. Other ways to deter the symptoms of CVS are to set up your work area in such a way that it is easy to view your computer screen, which should be straight in front of you, about 24 inches away from your eyes, and out of the suns glare. In addition, you may use a desk lamp to create a more focused light where you are working. For more information ask you doctor about computer vision syndrome or CVS.

HI-INDEX LENSES

Thick, heavy and cosmetically unpleasing spectacle lenses are quickly becoming a thing of the past. Thanks to modern technology, high index lenses are changing the way we look and improving the way we see. As your eye becomes more myopic or nearsighted, light comes to a focus further in front of the retina. To get your focus back onto your retina, your prescription must get stronger. As your prescription gets stronger, this results in increased lens thickness, especially around the edges of the lens. It will also result in increased lens weight, causing discomfort while wearing your glasses. In an attempt to control the cosmetic appearance of your spectacle lens, ophthalmic manufacturers have begun to replace standard lens compounds with new high index materials. These new high index materials dramatically reduce both lens thickness and lens weight. This will make your lenses lighter, better looking, and more comfortable. High index lenses reflect more light than normal lenses. Ask your doctor about an anti-reflective coating to correct this.
