Single vision lenses are the most common type of prescription lens. As the name suggests, they have one consistent optical prescription throughout the entire lens. That means they’re designed to correct only one field of vision—either for seeing far away (distance vision), reading (near vision), or intermediate tasks like computer work.

Who Are They For?

People under 40 with either nearsightedness (myopia), farsightedness (hyperopia), or astigmatism tend to benefit most from single vision lenses. They’re also a great option for anyone who needs help seeing clearly at one specific distance, whether it’s reading up close or seeing far away. These lenses are also perfect for people who want a simple, affordable solution—like dedicated reading glasses or driving glasses.

Progressive lenses are multifocal lenses without visible lines. They offer a smooth, gradual transition between three focal points: distance, intermediate, and near vision—all in one lens. Think of them as a more advanced and seamless alternative to traditional bifocals or trifocals.

Who Are They For?

Progressive lenses are typically ideal for people over 40 who experience presbyopia, which is the natural loss of near-focusing ability that comes with age. They’re perfect for those who want one pair of glasses that can handle everything—reading, working on the computer, and seeing clearly at a distance. They also appeal to anyone looking for a clean, line-free lens design.

The most obvious difference between these two lens types is the number of vision zones they offer. Single vision lenses correct just one type of vision—either near, intermediate, or far—while progressive lenses provide correction for all three. Single vision lenses tend to be more affordable and easier to adjust to, especially for first-time wearers. Progressive lenses, while more expensive, eliminate the need to carry multiple pairs of glasses and offer a more seamless experience for people with age-related vision changes. In terms of appearance, single vision lenses have a uniform look, while progressive lenses look just like regular glasses from the outside, but contain invisible zones that require a short adjustment period to get used to.

Progressive lenses do require a bit of an adaptation period. Because the lenses are designed with multiple vision zones, it may take a few days to a couple of weeks for your eyes and brain to adjust to the new way of seeing. But once you’re used to them, many wearers find them more convenient than constantly switching between different pairs of glasses.
