Many readers may not be particularly familiar with the types of progressive multifocal lenses, so this article introduces four progressive lens styles for your reference: bifocal reading glasses, reading line-free bifocal lenses, photochromatic/transition progressive lenses, and high-definition progressive lenses.
Bifocal Reading Glasses
Some hyperopic (farsighted) patients prefer to have “plano” or no prescription at the top of the lens and a reading prescription at the bottom, so they can wear their glasses all day without having to constantly put them on and take them off.
Reading Line-Free Bifocal Lenses
They are also known as bifocal reading glasses. Even if someone wears non-prescription readers, PALs can have no Rx at the top and reading power at the bottom without a doctor’s prescription.
Photochromatic / Transition Progressive Lenses
One of the coolest lens options is the gradient progressive lens, also known as photochromatic lenses. These lenses darken when exposed to ultraviolet light and are available for almost all lens types and most prescriptions. This is a popular choice because they protect your eyes from harmful UV rays.
High-Definition Progressive Lenses
High-definition progressive lenses are actually a marketing strategy for digital lenses. Free-form progressive lenses can produce more personalized and precisely finished lenses. Back-surface progressive lenses are free-form progressive lenses with the prescription placed on the back surface of the lens. The advantage of this is that the power distribution is closer to the eye.
We strongly recommend that you customize your progressive lenses because they are tailored to your specific needs—down to the frame, prescription, and even your lifestyle. They may cost a few hundred dollars, but specific measures are taken to improve peripheral vision. Determining the best type of progressive lens comes down to the specific measurements around your eyes and your requirements for your new glasses.
