Our office offers an array of eyeglass lenses to meet individual vision requirements.
Quality Lens Materials
High Index Lenses
Thinner, lighter, and flatter than ordinary lenses. These are ideal for high prescriptions that would otherwise involve very thick lenses, or even impractical in glass or plastic. It’s a special type of plastic with a refractive indexes of 1.56, 1.6, 1.64, 1.67, 1.7, and 1.74. The refractive index of a material is how much it bends light. Water, for example, has an index of 1.3330, which you can see if you put a spoon into a glass of water. It is our most-recommended material for adults.
Trivex lenses are thinner and more lightweight than plastic or glass, but not quite as light as high-index lenses. More impact-resistant than all other materials, and are ideal for people who work in construction, children, or people who just habitually get scratches on their glasses. Trivex can get a bit heavy for very high prescriptions, but it still about 10% lighter than polycarbonate lenses. Trivex lenses have optics similar to plastic, which is a good thing. Trivex also has UV protection built-in.
In addition to Trivex, we recommend polycarbonate lenses for children because of their impact resistance – they are not going to shatter or splinter if impacted. They are also relatively lightweight compared to plastic and glass. Like Trivex, it has built-in UV protection. Although polycarbonate lenses weigh more than Trivex, higher prescriptions may be thinner lenses. Polycarbonate lenses are among our least-expensive options.
Glass & Plastic Lenses
Due to safety concerns and technological advancements, glass and plastic lenses are now quite rare, and we never recommend their use. They are more dangerous if impacted, can be very heavy and thick, and don’t provide UV protection.
Types of Lenses/Options
Polarized lenses reduce glare and provide protection from harmful UV rays. The sun’s ultraviloet rays are the leading cause of cataracts, skin cancer around the eyes, and may contribute to macular degeneration – it’s a very good idea to have them filtered out by your glasses! They are the top choice for sunglasses.
Transition lenses are one of the more technologically-innovated lenses we have to offer. Molecules in these lenses are completely clear indoors and away from the sun, but change quickly to sunglasses when they are brought into sunlight.
There is no cracking or film – the materials that change color are part of the lens itself.
Transitions Signature – Transitions Signature are the seventh generation of Transitions lenses, and it shift from regular glasses to sunglasses is the fastest available – they are more reactive to ultraviolet light, and so can be used in more conditions.
Transitions Xtractive – These are activated by ambient light, and will get darker even in a car with UV-filtering tint, and will be tinted slightly in harsh, bright fluorescent light.
Transitions Vantage – These glasses not only tint, but polarize – with variable polarization for indoor and outdoor use. Essentially, these can be thought of as polarized transitions.
Transitions Drivewear – Drivewear transitions remove glare from the road or car hoods. In low-light and overcast weather (when it happens in Tucson…), it changes to a slight green-yellow tint that provides high contrast and minimizes glare. When driving, it changes to a copper color, enhancing color recognition and depth perception for the safest, most comfortable driving vision possible

These types of lenses feel much clearer than regular lenses and reduce glare from overhead and oncoming lights or reflections.
Less glare means less-tired eyes, and fewer headaches. They also look better cosmetically because they don’t reflect lights, so people can see your eyes. No-glare lenses also stay cleaner – Scotchgard protection repels the dirt, oil, and water that are constantly getting on your lenses. This also leads to less minimize washing, less fogging of your lenses.
We recommend these for everyone, but particularly if you do a lot of night-driving, spend a lot of time in front of a computer screen often, or photographers who look through a camera lenses often. Consider no- glare lenses for all these practical uses, for sure there will come a time when you wish you owned a pair.
Progressive Addition Lenses
Progressive lenses are what we recommend to for near, middle and distance vision. Progressive lenses transition smoothly from distance to near. Because of the smooth transitions, you won’t see the lines of a bifocal or trifocal lens. This feels more natural to the eye, and is less distracting to the wearer. We use Varilux brand progressive lenses.
Bifocals and trifocals provide vision at specific distances, which is necessary for some patients, but only correct at those distances. Because of that choppiness, although they can be less expensive than progressive lenses, we generally recommend progressive lenses.
Manufacturing Turn-around Time
Generally, we get lenses back in 7-10 business days, for a total of a week-and-a-half or two weeks.
We can get this fast turnaround be cause we rely on Bristow Optical, just a few miles from our central office, to manufacture our lenses. They do a great job, we’ve always been very happy with their work, and we feel fortunate that we can work with a local optics lab that’s so close by. The only exceptions are when some lenses are done by insurance labs, but this isn’t very common.
Frame & Lens Warranties
WE GUARANTEE that your new eyewear was manufactured with materials of the highest quality, strength and durability, and is free from defects. If any part of your frame or lenses break, under normal wearing conditions, within one year from the date of purchase, return all parts and we will repair of replace it at no charge.
Replacement of plastic lenses purchased with an extra scratch coating, antireflective coating, polarization or polycarbonate is limited to once in a 12 month period. Lens replacement must be in the original prescription. Limited warrantee does not cover: loss, theft, accident, abuse, CR/39 lenses or glass lenses. Some limitations apply.
