The frame gets the attention, but the lenses do the work. Choosing the right lens type, material and coatings can make glasses more comfortable for your daily routine.
Here is a simple guide to the main options, based on information from the American Academy of Ophthalmology.
Key takeaways
- Single-vision lenses correct one distance; multifocal lenses correct more than one.
- Progressive lenses have no visible line, but the AAO notes they can cause more distortion than other types, so a good fit matters.
- Polycarbonate and Trivex are impact resistant; high-index lenses are thinner for strong prescriptions.
- Anti-reflective coating can reduce glare, and photochromic lenses may not darken well in cars.
Lens types
Single-vision lenses
Single-vision lenses have one prescription across the whole lens. They correct nearsightedness, farsightedness or the near-focusing change called presbyopia.
Bifocals and trifocals
Bifocals have a distance zone on top and a reading zone below, with a visible line between them. Trifocals add a middle zone for arm’s-length tasks.
Progressive lenses
Progressives provide distance, intermediate and near vision with a smooth transition and no visible line. The AAO notes they can cause more distortion than other types, so accurate measurements and fit are important. See our comparison of progressive lenses and bifocals.
Computer glasses
These are designed for screen distance, usually about 20 to 26 inches from your face, and can help reduce strain during long hours at a desk.
Lens materials
| Material | Good to know |
|---|---|
| Plastic | Lighter and less likely to shatter than glass |
| Polycarbonate | Highly impact resistant; often recommended for sports and other activities |
| Trivex | Meets the same safety standards as polycarbonate and is less distorting |
| High-index | Thin and light, useful for stronger prescriptions |
Coatings and add-ons
- Anti-reflective coating reduces glare and can help with night driving.
- UV protection shields your eyes from the sun’s ultraviolet rays; the AAO notes some plastics already include some UV protection.
- Photochromic (light-adjusting) lenses darken in sunlight, but the AAO says they do not work well in cars or airplanes.
How to decide
Think about your daily routine: screens, driving, sports, reading, and how strong your prescription is. Bring your questions to your optician, who can measure and show you options. Learn more about our lens options.
Frequently asked questions
Do I need to spend more on lenses than on the frame?
Not always, but the AAO points out that spending more on frames does not guarantee better eyeglasses, and quality lenses are worth considering.
Can I get lenses for safety or sports?
Ask about impact-resistant materials such as polycarbonate or Trivex, which the AAO describes as impact resistant.
