Cycling With Poor Eyesight — Prescription Glasses or Contact Lenses?

Poor eyesight doesn't rule out cycling — it only rules out riding half-blind. Blurred kerbs, unclear signs and potholes you see a fraction of a second too late are a real risk. Fortunately you have several good options, from contact lenses to glasses with a prescription insert. Here's which one works, and when.

Contact lenses — the most convenient on the bike

For most cyclists with poor eyesight, lenses are the first choice. Advantages:

• A full, unframed field of view — nothing blocks your peripheral vision, which matters in traffic.
• You can wear any sports glasses on top, tinted or photochromic included.
• They don't fog up or slip off your nose over bumps.

Downsides: on long rides and in the wind, your eyes can dry out (lubricating drops help), and dust under the lens can be unpleasant. Daily disposable lenses are the most practical here — after the ride, you simply throw them away.

Prescription glasses with an RX insert

If you don't tolerate lenses, reach for sports glasses with an RX clip-in insert — a small frame with your prescription, mounted on the inside behind the lens. You get protection from wind, insects and sun plus correction in one.

• Works for moderate prescriptions; with strong dioptres the insert can get thick and heavy.
• Downsides can include fogging and a smaller field of view than lenses.

Fully prescription-ground glasses

Sports frames with the correction ground into the full surface of the lens give the best image quality for strong prescriptions, but they cost more and are harder to swap for tinted lenses. This is an option for people who don't correct with lenses and ride a lot.

Astigmatism and progressive lenses — a note

With astigmatism you need toric lenses or an RX insert that accounts for the axis — plain "minus" correction isn't enough. If you wear progressive glasses for reading, remember that on the bike it's distance vision that matters — for riding, distance correction alone is usually enough.

What not to do

• Don't ride with no eye protection at all — an insect or a stone at 30 km/h is a serious injury. Even without a prescription, glasses are worth having.
• Don't wear ordinary everyday prescription glasses on a fast descent — the lenses and frame aren't impact-resistant.

Summary

The simplest route is contact lenses plus good sports glasses; the alternative is glasses with an RX insert or full prescription lenses. The choice depends on the strength of your prescription, comfort and budget — if in doubt, check with an optician.
