Lenses

A wide range of lens products are available to the consumer. Verona Vision Care staff and doctors will recommend the best product for each patientís needs.

Single Vision

Single vision lenses have one power throughout the entire lens. It can be used for distance, for reading, computer distance or for any one particular distance the patient wants or needs (ie. Piano).

Bifocal

Bifocal lenses have 2 different powers designated by a line. Most typically, the top of the lens is for far away and the bottom, inside the half moon shape, is for near. However, sometimes computer distance and reading can be used or distance and computer. It is important to know what the glasses will be used for so the doctor can prescribe accurately.

Trifocal

Trifocal lenses have three different powers, designated by lines. The top of the lens is typically for distance, the middle is for intermediate which is just beyond arms reach to about five feet and the bottom is for near or anything that the wearer can actually touch.

Progressive

Progressive lenses, also known as no-line bifocals, are actually a multifocal lens. The top of the lens is for the distance, the middle is for intermediate and the lower part of the lens is for near. Since the lens does not have any lines, there is a channel effect down the center with the clearest vision. Therefore, there is some distortion in the periphery in order to have all the powers blended into the lens.

Standard Progressives vs. Premium Progressives

All progressives have the clear usuable "channel". Premium progressives are made with newer technology which creates a wider channel, more usuable areas and less blurriness to the sides. Each year many new progressives come on the market.

Standard vs. Premium vs. Elite Progressives

All progressives have the clear useable "channel". Premium progressives are made with newer technology which creates a wider channel, more useable areas and less blurriness to the sides. The newest progressives are digitally surfaced using computerized technology allowing lenses to be more customized. Elite progressives are customized to the frame chosen, the prescription and how the frame is worn. Each year many new progressives come on the market.




Lens Materials

Glass

This material has the best optics and clearest vision. It does not scratch as easily as other materials. It is not often used anymore because of safety; when hit with something, the glass can shatter causing shards to hit the eye. It is also quite heavy for most prescriptions.

CR-39

Also known as plastic, this material is much lighter and less breakable than glass.

Polycarbonate

Ten times more impact resistant than plastic or glass lenses, this is an acceptable choice for those who work in certain occupations where safety is important. This material is thinner and lighter than glass or plastic and has built in UV protection. Since it is a softer material, it scratches and dents more easily.

Trivex

Trivex material is known for its impact resistance that is equal to polycarbonate but optically (how one would view through the lenses), it is superior to polycarbonate. It has built in UV protection and is the best material for drill mount frames as it does not crack or stretch out around the drill holes. It is much more scratch resistant than polycarbonate because it is a harder material. A lens of choice for children and teens and anyone who wants a light and durable lens.

High Index

This is the thinnest, lightest and flattest material available for lenses. Those with farsightedness will appreciate the less magnified look of their eyes and nearsighted prescriptions do not have as much bulk on the edges. This lens material has built in UV protection.




Lens Options

Antireflective Coating

Antireflective coating is applied to the front and backside of each lens and allows light to pass through so the lenses donít have reflections on the outside of them. Cosmetically itís nice because the wearerís eyes are seen rather than reflections. Most importantly, it allows clear vision and less eyestrain to the wearer especially when driving at night and working on computers.

Transition Lenses

Transition lenses are acceptable for those who want the convenience of sunglasses outside, without having to switch glasses. They get dark quickly when exposed to direct sunlight, however, will not darken in a car since the windshield blocks out the UV rays. When going from outside to inside, they change back to being clear in about 5 minutes. The newest transition lenses change into polarized sun lenses.

Polarized Lenses

Polarized lenses are sunglass lenses that reduce glare, therefore making it an extremely safe lens. It is recommended for any sunglass usage but especially for water sports and every day driving.

Drivewear Lenses

Drivewear lenses are a Transitions sunglass lens that will always have at least a small sunglass tint to it. It will darken according to light conditions, even inside the car. This lens is polarized so is ideal for those that drive many hours a day.

Neox Lenses

Neox lenses are a new lens developed for outdoor sports enthusiasts, where contrast is important. The lenses are engineered to enhance critical elements while providing superior optical clarity, increased contrast sensitivity and depth perception. The lenses adjust to the light levels also. They are good for golf, skiing or any other outdoor sport.
