Multifocal lenses let you see comfortably at different distances. They allow you to see close, near, or far without changing your glasses. There are other kinds of multifocal lenses like bifocals and trifocals, but progressive lenses differ because of their smooth transition between prescriptions.
Bifocals and trifocals work similarly to progressive lenses and feature either two or three prescriptions in a pair of glasses. These lenses have definitive lines separating the prescriptions.
Progressive lenses are typically worn by people affected by presbyopia. This condition is typical in adults over 40 and affects your ability to focus on nearby objects. Your optometrist can recommend progressive lenses suitable for you. Fit is the most important aspect of progressive lenses. Your glasses need to feel right and function well for your needs.
There are several different types of progressive lenses, including:. Computer progressive lenses or near variable focus lenses are designed for clear vision in office settings. These lenses are ideal when using the computer for over 4 hours per day and help to reduce visual fatigue digital eye strain. These lenses are intended for indoor use and should not be worn over your regular glasses.
The downside to this is it requires you to have two separate pairs of eyeglasses. Premium progressive lenses are designed to provide a wider and smoother view. These lenses are highly customizable for your prescription, chosen frame, and eye anatomy.
Premium progressive lenses typically incorporate your dominant eye into the design. To be seen clearly, objects must be within a specific range of distances. Objects that are outside the distances covered by the bifocal or trifocal lens powers will be blurred. Progressive lenses, on the other hand, have a smooth, seamless progression of lens powers for clear vision at all distances.
Progressive lenses provide a more natural depth of focus with no "image jump. It's important to note, however, that the first time you wear progressive lenses, you may notice a soft blur in your peripheral vision through the lower half of the lenses, to the right and left of the intermediate and near zones. If this occurs, the sensation typically will go away after you wear the lenses full-time for several days.
If it persists, tell your eye doctor or optician. If necessary, a slight adjustment or changing to a different progressive lens design usually will solve the problem. Because of their visual and cosmetic advantages over bifocals and trifocals, progressive lenses have become the most popular multifocal lenses for anyone with presbyopia who wears eyeglasses.
In early progressive lens designs, the lateral field of view for computer use and reading was somewhat limited. This required wearers to make frequent small head movements and "point their nose" directly at an object to see it clearly. In today's progressive lenses, the size of the zones for computer use and reading has been increased.
And for computer users, special occupational designs greatly expand the intermediate zone for enhanced comfort at the computer. You can also look ahead to see your computer or someone sitting across the dinner table through the intermediate section.
If you drop your gaze downward, you can read fine print comfortably through the bottom of the lens. There is a corridor that runs vertically down the middle of the lens and measurements will be taken to fit the corridor in the right place so all powers can be accessed comfortably.
Progressives also eliminate a problem called "image jump" which is experienced with bifocal and trifocal lenses. The lines on the lenses create a drastic change in power which causes images to appear to jump as you move from distance to near. Progressives create a smooth, more comfortable transition from distance to near and back. The newest, best version of these lenses provides the closest thing to natural youthful vision that a presbyopic person can achieve.
Progressive lenses provide an uninterrupted view of the world with a gradual focus change from far to near and everything in between without the traditional bifocal line that so many perceive as ugly and a sure sign of aging. The best brand of progressive lenses is far superior to conventional bifocals or trifocals in virtually every comparison except price. Yes, progressive lenses are technologically superior to bifocals and do cost more.
Many optometrists and opticians also recommend that when you purchase progressive lenses you should buy the best the optical store has to offer. Vision distortions, narrow viewing areas and the inability to adjust to your progressive lenses are much more common with inferior quality brands of progressive lenses. Patients must learn about progressive lenses so they can understand how to use them and what to expect.
Remember to point your nose directly at what you want to see. Then raise or lower your chin until the object comes into the best focus. You may feel an initial difference in peripheral vision that will require some slight changes in horizontal head and eye movement.
This will diminish with wearing time. Most people will adapt in a few hours although some can require as long as two weeks. If you are not adapted within two weeks you should return for a consultation with the optician that fitted your eyeglass frames to your face. If the initial frame measurements are slightly displaced you will not be looking through the proper part of the progressive lens.
Therefore, you will experience blurred vision or an inability to feel right visually when wearing the lenses. Otherwise, you can limit your near vision, so if you prefer small, less noticeable frames, premium progressive lenses are the better choice.
The cost of progressive lenses is a little higher if you choose premium vs. However, you can look forward to a broader viewing area and less visual distortions when you select premium progressive lenses since they are custom-made for your eyes. Your eye doctor will also size your frames for your lenses to give you the best visual experience.
If the price is a factor, opt for standard progressive lenses. However, if you have a complicated prescription or need customized lenses, premium progressive lenses are the better option. Either way, the new glasses will help get your vision back on track.
One of our optometrists can give you a comprehensive eye exam to identify your vision needs. From there, they can suggest standard vs. For those who require three prescriptions, progressive lenses are a natural choice.
However, considering how many types of progressive lenses are on the market, it can be challenging to narrow down your options. Two of our most popular choices include standard and premium.
