There are basically three types of lenses for
near vision needs:
Bifocals, a single line lens is available in plastic, polycarbonate and glass. There are three sizes available in plastic. Flat top 28, 35 and 45 millimeter widths.
The depth of the bifocal section or segment is determined by how high your optician sets your bifocal segment in your lens.
Usually the segment is set at the wearers
bottom eyelid or slightly above it. If the bifocal
segment you are wearing seems like it's in your
line of sight for distance, or you feel like you have
to raise your head too much to read, you should
mention the issue to your optician so they can help you explore your options.
Trifocals are a two line or segment lens. The upper segment is your trifocal or intermediate focal length. It is used for distances of three to four feet or arms length. The lower segment is your bifocal and is the area of your lens you'll read fine print with. The bifocal is the strongest portion of the lens. Trifocals are available in Flat top 28 and 35.
Trifocal depth is determined by two factors; the depth of the actual trifocal segment and how high your optician sets it. Again, the top segment is usually placed at or slightly above the wearers bottom eyelid. If there are issues with your current trifocal height, please alert you optician.
Bifocals & Trifocals
Progessive or no line bifocal lenses are often mistakenly called bifocals and trifocals. The truth is, progressive lenses contain both. While many younger presbyopes only need bifocals, they will find that the intermediate zone in progressive lenses is weak enough that it won't affect them much.
While bifocals and trifocals are basically "point and shoot" lenses, progressive lenses require a little time and effort to get used to them but usually give the most visual capability.
Progressive lenses offer more focal lengths through the progressive "corridor" than bifocals or trifocals. The trade off is that these lenses have a more narrow viewing area (see the diagram to the left). They are also many times the most optically sound lenses.
Most of our patients can be successfully fitted with
progressive lenses by our expert opticians. Be aware
that an improper fit for progressive lenses can have
disastrous results. In fact, that's why many former
progressive wearers won't consider trying them. They
went somewhere where the opticians didn't know how
to properly measure for them and then fit them, therefore their progressive lenses never worked for them.
Payton Optical has a progressive lens to fit every
lifestyle. We have lense designs that will fit big frames and we also know the lens design that will fit the trendy
rectangular frames. Further, we have the new digitally
ground lenses for unsurpassed clarity and ease of use!
