Most of what you pay is lens, and almost nobody explains it. Here is every option we fit, what it does, and what it costs on top of the frame.
One prescription across the whole lens. Distance, reading, or intermediate for screens. The simplest and the one most people need.
Distance at the top, reading at the bottom, blended between. Fine for most people, with a narrower clear zone at arm’s length.
The version worth paying for if you use a computer all day. Wider intermediate zone, less head movement, quicker to adapt.
For prescriptions past about 3 dioptres. Thinner edges, lighter frame, and less of the bottle bottom look. Not needed under that.
Darkens outdoors. Genuinely useful, with one honest caveat: most types barely react behind a car windscreen.
The evidence for eye health is weak and we will say so. Some people do report less glare at night, which is a real if smaller benefit.
Anti reflective, scratch resistance, and UV are standard on every lens we fit and cost you nothing extra. Being sold them as a premium package is the single most common way people overpay for glasses.
