A summary of the variety of frames and lenses available at Granger Eye Studio.

We will design all the components that make up your pair of prescription lenses. It is important to select the right combination of these elements for your unique visual needs and to always consult your eye care professional if you have any questions.

The knowledgeable staff at Granger Eye Studio will consider many elements when suggesting a new pair of eyeglasses—such as long-term wearing comfort, frame style, features and function. It is the way all of these elements are combined that create your custom designed eyeglasses, which will become as unique as the person wearing them.

Anti-Reflective Coating

Normal eyewear often creates glare, reflections, and “ghost images.” Now all that can be eliminated with an anti-reflective coating.

What we see is a result of light being sensed by our eyes. With normal glasses, much of the light reflects off the lenses. This produces glare. It also reduces the wearer’s visual acuity. In other words, the light reflection is both a cosmetic and visual problem.

Anti-reflective coatings increase light transmission through the lenses to 99.5 percent. They make it easier to see and easier for others to see you. These coatings are especially useful for those viewing computer screens and driving at night.

Bifocal Lenses

For many people, different lenses are needed for seeing at different distances. Bifocal lenses allow the wearer to look through two areas of the lens to see clearly at two different distances. One area focuses on distant objects. The other is used for reading. A little-known fact is that bifocals were invented by Benjamin Franklin, and his style of bifocals are still available today.

Most of the time the “reading” area is smaller, shaped like a sideways “D”, and found in the lower hemisphere of the lens. These bifocals are called line bifocals or flat-tops. If you are focusing on distant objects, you look through the top half of the lenses. To read a book, magazine, or newspaper, you look through the “reading” area. The Franklin style lenses are less common, and are split horizontally down the middle of each lens. One thing that is difficult about using bifocals is dealing with the line between the two vision areas. Fortunately, recent technologies have developed a new type of lens, called the “no-line”, or progressive, lens. This technology has grown by leaps and bounds and at Granger Eye Studio we offer the latest technology—digital lens surfacing—which offers “high definition” vision in your new eyewear.

Cosmetic and Specialty Tints

Besides being stylish, sometimes attention needs to be directed towards the function of your eyeglasses. Specialty tint can provide a more comfortable visual experience when you spend lots of time in front of a computer or when driving during daylight hours. We can design these tints to suit not just your personality but to enhance your eye wear experience anytime! Speciality tints offer a variety of colors and shades and can be both functional and great looking as well Computer Vision Syndrome is becoming more common and we have found that unique tints can reduce the eyestrain caused by excessive computer or cell phone use.

High Index Lenses

Previous to the last few years, the only materials available for use as lenses were glass and a hard resin called CR-39. But recently, high index lenses have become available. High index materials are named because they have a higher index of light refraction. Basically, they can do the same job that glass or CR-39 does, but high index lenses are much thinner and lighter. With high index lenses, you can avoid having “soda bottle” lenses. More stylish, more functional and more modern.

When learning about high index lenses, you may hear many unfamiliar numbers and terms. Here are a few things to remember.

Polycarbonate
The first and still the most popular high index plastic is polycarbonate. Polycarbonate was originally developed for fighter jet cockpits. It is very strong, very light, and resistant to scratches and breaking. Most sports lenses are made of polycarbonate.

Mid-Index
Other high index materials are classified by numbers. The higher the number, the thinner and lighter the lens. The lower numbers are classified as mid-index lenses. Mid-index lenses, such as 1.54, 1.56, and 1.57, are thinner than glass, and nearly as strong as CR-39.

High-Index
High index lenses, such as 1.66, 1.74, and 1.9, are much thinner than regular glass or plastic. Talk with your doctor to decide which high index lens is right for youThe lenses are specifically designed to be more effective at bending light with less thickness and less weight ---which equals a more modern, high quality visual experience.

Progressive Lenses

One of the main problems with bifocal and trifocal lenses is the problem of eye fatigue. It is difficult to switch from one focusing power to another. It can make your eyes tired, and it can even lead to a headache, sore neck and sore back.

A recent variation of bifocals and trifocals is the no-line lens or progressive lens. The “No-lines” optical design provide a smooth transition from focusing on nearby to focusing on distant objects because they do not have a distinct line which separates the focusing powers. Instead, a gradual change in power allows the wearer to focus on objects at all distances. Distant objects are viewed through the upper portion of the lens, while near objects are viewed through the middle or lower portion of the lens. These are also great for computer users. If you work at desk with a computer all day, this is a great solution to computer vision problems.

Photochromics

If you have ever felt frustrated at needing both prescription glasses and prescription sunglasses to accommodate an outdoor lifestyle, you should consider photochromic lenses. Photochromic lenses darken when exposed to UV rays. The change is caused by photochromic molecules that are found throughout the lens or in a coating on the front of the lens. When the wearer goes outside, the lenses darken or tint. When the wearer goes back inside, the glasses become clear.

There are a variety of photochromic options available. Depending on what you choose, you can customize the lenses to your needs. Some lenses darken only in direct sunlight, while others darken in little or no direct light. Some are designed to darken while you are in the car to reduce road glare while you are driving. You can even choose the color of the tint. Ask your doctor what options are available.

Polarized Lenses

Glare from wet roads, light reflecting off other vehicles, and glare from your own windshield can be annoying and dangerous. To eliminate this glare, we offer polarized lenses. Polarized lenses eliminate almost all glare, reducing eye strain and increasing visibility. Polarized lenses are the most effective way to reduce glare.

If you are a fisherman, golfer, jogger, biker or professional driver; you will find that polarized lenses provide a huge visual benefit. If glare is an issue for you or someone you know, contact Granger Eye Studio and make an appointment with Dr. Granger.

Scratch Resistant Coating

If you have hard resin lenses (CR-39), you should consider getting a scratch resistant coating. Resins and plastics are more susceptible to scratches than glass. Scratches damage the cosmetic look of the lenses and compromise their performance. With a scratch resistant coating, you do not have to worry as much about minor scratches on your lenses.

Another advantage of scratch resistant coatings is that most coatings come with a one-year warranty. They are a great investment to prevent minor scratches. However, it is important to remember that scratch resistant does not mean scratch-proof. All lenses are susceptible to scratches.

Specialty Lenses

We all have heard the phrase, “Different strokes for different folks.” Well, this also holds true when it comes to selecting glasses. There are different lenses for just about everybody. No matter what your particular need, there is probably a specialty lens designed for you.

For example, a specialty lens that is becoming increasingly useful is designed for computer users. Computer lenses have “windows” designed for viewing your computer screen, documents on your desk, and distant objects. The lenses are designed to reduce Computer Vision Syndrome, or CVS, which is characterized by headaches, eye strain, neck and back aches, dry eyes, blurred vision, and double vision.

Another example is called the double D-segment lens, also known as the double flat-top lens. If you look through most of the lens, you can focus on distant objects. But you can also look through a D-shaped segment near the top of the lens to see nearby overhead objects more clearly. This is very useful if you are involved in work where you are looking at nearby objects above your field of vision, as with carpenters and pilots. The D-shaped segment near the bottom of the lens allows for reading.

Trifocal Lenses

Bifocals allow the wearer to read through one area of the lens, and to focus on distant objects through another area of the lens. As the eyes age, though, a stronger prescription is often needed to read. This would be fine, but the stronger prescription that allows for reading makes it difficult to focus on objects at intermediate distances, such as grocery items on a shelf or your speedometer. Thus, trifocals are necessary for a third prescription for intermediate focusing.

Trifocals, also known as line trifocals, feature three areas of focusing power, each separated from the other by a distinct line. The three windows allow for focusing on distant objects, intermediately distanced objects, and for reading. The downside of trifocals is dealing with the lines between the different focusing powers. Fortunately, recent advances in technology have led to developments in no-line, or progressive lenses.
