How to choose the right lens type

The short answer: the lens type follows what you need to see. Single vision corrects one distance; progressives and bifocals cover near and far for presbyopia after 40; computer lenses are set for screen distance; and reading glasses handle close-up only. Add an anti-reflective coating to any of them, and high-index if your prescription is strong.

You need Lens type
Distance only (driving, TV) Single-vision distance
Close-up only (reading) Reading glasses / single-vision near
Both far and near, age 40+ Progressive (or bifocal)
Mostly screens and desk Computer / office lenses
From our test bench. The mistake we see most is using reading glasses for the computer. A screen sits farther than a book, so readers leave the monitor soft and push people to lean in. Match the lens to the distance you actually use it at, and most eye strain eases on its own.

Lens type FAQ

What is the difference between single vision and progressive lenses?

Single vision has one power across the whole lens for a single distance. Progressives blend near, middle and far in one lens with no visible line, which suits presbyopia after 40 when you need both close-up and distance.

Do I need computer glasses?

If you spend hours at a screen and standard glasses leave it slightly blurry, computer lenses set for screen distance help. What eases strain most is anti-reflective coating, good setup and the 20-20-20 rule, not blue-light filtering.

At what age do you need progressives?

Usually the mid-40s onward, as presbyopia makes close focus harder. If you already wear distance glasses and start holding things at arm's length, progressives put near and far in one pair.

Can this tool replace an eye exam?

No. It points you toward the right lens type, but only an eye exam gives your exact prescription and confirms the best lens for your eyes. Use it to shop with a clearer idea of what you need.
