Multifocals is a general term that encompasses bifocals, trifocals and progressives lenses. 1st Street & Village Eye Centres we explore some of the myths that surround Progressives & other multifocal lenses, and a couple frequently asked questions we have had at our Edmonton & Sherwood Park Eye Centre’s:
“I heard it is hard to get used to bifocals?”
The visible line bifocals are easier to adapt to than the invisible Progressives. The learning curve varies from patient to patient & can be somewhat dependent on the Rx, the frame and lens style. In the progressive design it is necessary to look through the top part of the glasses to view distance, and then lower your eyes to look through the bottom part of the glasses to read text up close. There’s a little practice to learn to look through the correct part of the lens for the correct visual task, but once you have adapted to the Progressives, the benefits become obvious.
The younger you are and weaker the reading Rx the easier it is to adapt. The higher quality, newer technology progressive designs will be easier to work with as they provide fewer distortions.
“I don’t want to wear bifocals, it will make me look like my parents!”
Multifocals come with the traditional visible line variety in the way of flat top bifocal or trifocal. These lenses only provide vision for far and near. The multifocal called the progressive additional lens provides vision in all distances, including the intermediate or computer vision.
“Is there a difference when I pay more for a progressive lens?”
Yes. The progressive design does vary in quality. The best progressive lenses will provide the widest reading zone with very little blur. The top of the line progressive designs will have the advanced personalization including adjustments for height and posture. The newest Progressive technology provides the sharpest vision across the entire lens to eliminate peripheral distortion. It also gives the eye a more natural appearance for the observer, and has thinner lenses that are lighter. These lenses also account not only your prescription & standard optical measurements, but also the shape of the frame in which your lens will be placed. We often tend to visually and physiologically adapt to lenses that may not be optimal for us. These lenses offer precise optical stability because they are made with more surface optimization on the back surfaces providing more optimization zones throughout the whole lense.
Lenses are fully compensated for each patient’s vertex, fit height, pantoscopic tilt, general posture and frame wrap angle. Less expensive older technology standard progressives and even aspheric lenses are designed to cover many prescriptions with a few base curves, but they can’t precisely match most patients vision needs as well as the newest technology.
“I am on the computer all day, are there any lenses that can help?”
Yes. There are office progressive lenses for the emerging need for digital distance. These are specialized progressive design only for two distances instead of the traditional three. They are lenses that extend the intermediate zone (wider and comfortable for indoor vision), and others that extend the near zone (provides more range than reading glasses). You can usually walk around the office comfortably with these glasses on, but not drive a car.
Electronic screens from our LED monitors, laptop screens, phones and tablets emit a powerful blue light tinge. Long exposure to digital devices can cause eye fatigue, &/or strain symptoms such as headaches, dry or irritated eyes and blurry vision. Zeiss’s Duravision BlueProtect AR coating enhances screen contrast and protects eyes by reducing blue light.
“How can I protect the lenses to last longer?”
It is all in the anti-reflective coating you purchase. For instance, a hard coat will only provide scratch resistance. However, Zeiss’s Duravision or Nikon’s SeeCoat anti-reflective coating will provide you with more scratch resistance, provide longer lens durability, avoid dust accumulation on the lens and is optimized for transparency. These lenses give a more natural look, and will be easier to clean and keep clean while remaining smudge resistant.
Progressive Lenses Education
With so many progressive lenses manufacturers as well as styles of progressive lenses available from each manufacturer it’s easy to get confused. We welcome patients to come visit one of our eye care centers and chat with us about learning the best technology in progressive lenses to help each individuals needs. When you talk to us, let us know how you use your eyes each day and how your current glasses aren’t doing the job you would like. Bring in your glasses Rx, we’ll listen, check your current glasses and help guide you so your new progressive lenses from our suppliers will be the best progressive glasses you’ve ever had. If you would like to read a little more on the lense products we carry, visit our Eyeglasses resource page. There’s also a couple of good short educational videos there as well. For a quick overview, visit our Edmonton and Sherwood Park Optometrists locations page to plan a visit to our eye clinic nearest to you.
We look forward to your visit. If you are also in need of an eye exam, you can start arranging an appointment at our vision center from our appointments page now!
