Today’s progressive lenses make it difficult for others to tell you’ve reached “that bifocal age.” Progressive lenses, often called “no-line bifocals,” give you a more youthful appearance by eliminating the visible lines found in bifocal (and trifocal) lenses.
But beyond being simply a multifocal lens with no visible lines, progressive lenses provide other advantages also: mostly, the capability to see at all distances, including at arm’s length for computer use and up close for reading.
Why Do Progressive Lenses Better Than Bifocals
Bifocal lenses have only two powers: one for seeing across the room and the other for seeing up close. Objects between, like a computer screen or items on a supermarket shelf, typically stay indistinct with bifocals.
To try to see objects at this “intermediate” variety plainly, bifocal users must bob their direct and down, at the same time checking out the leading and after that the bottom of their bifocals, to identify which part of the lens works better.
Bifocals likewise put you at higher risk for computer vision syndrome (CVS) when using a computer for prolonged durations. Bifocal users need to sit closer to the screen and tilt their heads back to translucent the bottom part of their lenses. This unnatural posture can lead to muscle strain, neck pain and other symptoms of CVS.
Progressive lenses more closely simulate the natural vision that you enjoyed prior to the start of presbyopia. Instead of supplying simply two lens powers like bifocals (or 3, like trifocals), progressive lenses hold true “multifocal” lenses that supply a smooth, smooth progression of numerous lens powers for clear vision throughout the room, up close and at all distances in between.
With progressive lenses, there’s no have to bob your direct and down or embrace uncomfortable postures to see your computer screen or other things at arm’s length.
Holding your head in a comfy position, you can just look directly ahead to see in the distance, move your eyes somewhat downward to see your computer through the intermediate zone and lower your gaze a bit farther to read conveniently up close.
Natural Vision With Progressive Lenses
How do progressive glasses work? The visible lines in bifocals and trifocals are points where there’s an abrupt change in lens power. When a bifocal or trifocal user’s line of sight relocations throughout these lines, images unexpectedly move, or “dive.”
The pain caused by this “image jump” can vary from being mildly bothersome to developing nausea.
In addition, since of the minimal number of lens powers in bifocals and trifocals, your depth of focus with these lenses is limited. To be seen clearly, things need to be within a specific range of distances. Things 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, smooth progression of lens powers for clear vision at all distances. Progressive lenses supply a more natural depth of focus, implying there’s no “image jump.”
It’s crucial to note, nevertheless, that the very first time you wear progressive lenses, you might observe 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 happens, the sensation normally will go away after a week or 2 of full-time wear. If it continues, inform your optometrist or optician. Typically, changing to a different progressive lens style will resolve the issue.

How to use progressive lenses for computer? In early progressive lens styles, the lateral field of vision for computer use and reading was rather limited. This required users to make frequent little head movements and “point their nose” directly at a challenge see it plainly.
In today’s progressive lenses, the size of the zones for computer use and reading has actually been increased. And for computer users, unique occupational designs significantly broaden the intermediate zone for boosted convenience at the computer.
More comfort for active wear. With early progressive lens designs, first-time users regularly discovered soft blur and other peripheral aberrations that might offer the experience of motion or “swim” during quick head turns.
Today’s progressive lenses have better optics and fewer peripheral aberrations, making them really comfortable for active wear. A few of the newest high-definition lens designs discovered in modern-day progressive lenses are created with the very same wavefront-guided innovation used in LASIK surgery for crystal-clear optical performance over a broad field of view.
Compatibility with smaller frames. In early progressive lens designs, the power modifications within lenses required them to be reasonably large. This restricted frame choice to bigger styles.
Today, many progressive lenses have compact styles specifically produced smaller eyeglass frames. With these new styles, users with little faces or anyone who wants a smaller sized, fashionable frame can take pleasure in all the benefits of progressive lenses.
Better lens products. Today’s progressive lenses are offered in all the most recent lens products, making them thinner, lighter and more comfy than before. Progressives made from high-index plastic lens products can be approximately 50 percent thinner than basic plastic bifocals.
For safety eyewear, many brands of progressive lenses are readily available in lightweight and impact-resistant polycarbonate also.
