Lenses, not just frames
Prescription Sunglasses vs Clip-Ons
A second pair looks like sunglasses. A clip-on looks like a clip-on. The clip-on is cheaper and optically fine if it sits flat.

What you are paying for
A prescription sun pair is a full frame, full lenses, tint plus UV, optional polarization, optional mirror. You take the indoor pair off. A clip-on hangs extra lenses on the indoor pair. Magnetics are less ugly than the 1990s swing-up; they still add 8–15 grams on the nose.
Optically, a well-made clip that sits within 1–2mm of the host lens is fine. Air gap plus cheap film is how you get ghost images and edge glare.
When the second pair wins
Daily driving, water, a face that photographs, and any prescription over ±4.00 where a cheap clip will not match the curve. Acetate hosts take clips better than rimless. If you already chose acetate, a matching sun pair is easy to order in the same chassis.
- Rx sun: $90–$250 typical, looks like sunglasses
- Custom magnetic clip: $40–$120, looks like a clip
- Universal clip: $15–$35, often a bad gap — skip unless it is a travel spare
The hybrid nobody finishes
Photochromic indoor plus a clip ‘just in case’ is three solutions to one problem. Pick two at most: clear indoor, and either photochromic or a sun tool. If you drive, the sun tool should be polarized.
Questions, answered
- Do magnetic clips scratch the host lens?
- They can, if they rattle. Felt pads and a case. Do not throw them in a bag loose.
- Can a clip be polarized?
- Yes, and it should be if the point is driving. Ask. Many fashion clips are just dark.
- Is a fit-over sunglass better than a clip?
- For cycling and post-op wrap, yes. For looking like a person at lunch, no.
