Digital Lenses CR-39 Plastic Polycarbonate Lenses High Index Lenses Transitions ® Progressives Anti-Reflective Lenses Blue Blocker Polarized Lenses

Your lenses are the most important part of your glasses! Our staff can help recommend the best lens for you to optimize your visual needs and lifestyle. Some of these options include thin and light lenses, Transitions®, anti-reflective lenses, and customized tinting. We also offer several types of progressives (no-line multifocal lenses) for our presbyopic patients.

We make glasses here everyday! Most simple single vision prescriptions can be made within an hour or so depending on lens inventory. More complex prescriptions such as high index, bifocals, and progressives can be usually be available within a couple of days.

Digital Lenses

Today the world isn't just digital, it is high definition! Now your glasses can be too! Unlike conventional lenses, every Digital Lens is perfect, consistent and computer engineered to provide you with the clearest vision possible.

Digital lenses are custom made for you and your frame of choice and are available to you in a variety of lens designs and materials such as Polycarbonate, High Index, Progressives and Transitions. These lenses are ideal for those patients who have been unsuccessful with progressive lenses in the past. By combining each patient's unique measurements and this new technology, digitally surfaced progressive lenses provide wider fields of vision in all zones and virtually eliminate peripheral distortions and "swim".

You'll notice the difference the second you put them on!

CR-39 Plastic

For many years, CR-39 plastic has been the standard lens material for eyeglasses. Plastic lenses are half the weight of glass lenses, have better ultraviolet (UV) light protection, are less prone to shattering, and can be tinted more easily. With an added scratch-resistant coating, they are nearly as resistant to scratches as glass lenses.

Polycarbonate Lenses

Polycarbonate was one of the first "thinner, lighter" lens materials. Polycarbonate lenses are lighter than CR-39 plastic lenses. The most important feature of polycarbonate lenses is their impact resistance. Polycarbonate lenses are 10 times more impact-resistant than glass or regular plastic lenses, making them the preferred choice for safety glasses and eye wear for children and adults who desire lightweight, protective lenses.

High Index Lenses

High index plastic is a term used to describe a variety of plastic lens materials that are thinner and lighter than regular CR-39 plastic. These thin lenses come in a wide range of choices to make those thicker lenses as thin as possible. Today's high index plastic lenses sold in the United States range in refractive index from 1.54 to 1.74. One of the most popular high index lens materials has a refractive index of 1.67. Lenses of this material are about 50% thinner than lenses made of standard CR-39 plastic.

Transitions ®

Transitions are a photochromic lens that automatically changes from clear (indoors) to dark (outdoors) in just a few seconds. They block both UVA and UVB. These lenses offer superior comfort and convenience all in one pair of glasses. They are available in single vision, bifocals, progressives, polycarbonate and high index lenses.

Progressives

Progressive lenses are commonly referred to as "No Line Bifocals". Progressive lenses are the closest to how natural vision is before the onset of presbyopia that you can get in a pair of prescription glasses. They are more than just a defined near and distance correction in one lens. Rather, progressives provide a smooth transition from distance through intermediate to near, with all the in-between corrections included as well. This constant graduation of the prescription means that you can look up to see in the distance, look ahead to view your computer in the intermediate zone, and drop your gaze downward to read and do fine work comfortably close up.

Anti-Reflective Lenses

Anti-Reflective (or Anti-Glare) lenses improve both the vision through the lenses and the appearance of the glasses. Layers of filters on these lenses allow light to pass through the lens instead of bouncing back out as reflection. The result is that you'll see a reduction in glare, annoying reflections and halos around lights. This is a great safety benefit especially when you're driving at night. Also, anti-reflective lenses reduce both internal and external reflections on the lenses themselves, creating a nicer cosmetic appearance, making your lenses look almost invisible.

Blue Blocker

Blue light is known to cause short-term discomfort & serious long term damage to your eyes. Short term effects may include eye strain, headaches, physical & mental fatigue; while prolonged exposure to blue light may cause retinal damage & contribute to age related macular degeneration. Blue blocking lenses help protect your eyes from harmful blue-violet light in everyday surroundings including sunlight, indoor lighting & most digital screens.

Polarized Lenses

Polarized lenses are used in sunglasses to reduce glare from reflective surfaces such as the surface of a lake or the hood of a car. They accomplish this feat through a process called polarization, much like a venetian blind controls sunlight through a window. These lenses are 100% UVA and UVB protected and are the lens of choice for driving, boating and all sunny outdoor activities.

Contacts

---

Our doctors evaluate, fit and prescribe a large selection of soft disposable and rigid gas permeable (RGP) contact lenses. We fit single vision, bifocal, multifocal, monovision, colored and lenses that correct for astigmatism.

Soft contact lenses include daily, two week, and monthly disposable contacts. One of the recent advances in lens material technology is the introduction of silicon hydrogel lenses. These lenses offer higher oxygen permeability than other disposable lenses resulting in whiter and healthier eyes at lower risk for contact lens complications. In addition, these lenses allow for extended wearing time, in some cases FDA approved overnight wear.

Customized RGP lenses offer the best vision for patients with complex prescriptions. RGP lenses are also often prescribed to correct vision for patients who have keratoconus, a condition where the cornea becomes especially steep.

Dry Eyes

---

One of the most difficult conditions to treat is dry eyes. Most medical doctors as well as optometrists find dry eyes difficult to manage and provide comfort for their patients.

Recently, a company has developed a new frame and lens system which has had amazing results.

The frame is designed to block out almost all possible air tension which dries out the front of your eye. With this saftey net, prescription & non-prescription medications help to keep your eyes normally moist and comfortable.

No more itching, burning and abrasions from lack of adequate tears. We have placed patients in front of powerful fans and air-conditioning units with no resulting discomfort.

American Vision ® through our high tech labs can place almost any lens for vision correction in these frames. Progressive, bifocal, sunglass and Transitions ® lenses are only a few of the possibilities.

Please contact American Vision ® or your own ophthalmologist for more details and successful help with dry eye problems. We will work with your doctor to succeed.

Frames

---

American Vision carries one of the largest selections of frames in the area. Both of our offices stock over 5000 frames from most leading manufacturers. In addition to our designer frames, we also carry fashion frames made specifically for different lifestyles and various lens specifications. If there is a frame that we do not carry, tell us and we will do our very best to get it for you! Below find a representation of what you can expect to find at American Vision.

Our staff looks forward to helping you find the perfect frame shape and style for your personal look.
