If it has 45 by 26 mm of smooth lens, it fits.
Sunglasses, goggles, visors and headsets. Here is the honest verdict for each.
If it has 45 by 26 mm of smooth lens, it fits.
Point at a pair. The patch goes on the inside, over the pupil, straight edge up. Two identical lenses per pack.

The patch goes on the inside, over the pupil, straight edge up. You need about 45 by 26 mm of smooth lens.
SunglassesBEST
Flat or mildly curved sunglasses. The easiest fit. Centre it over the pupil, straight edge up, on the inside of the lens.
Fashion framesBEST
Fashion frames: cat eye, oversized, round. Flat fashion lenses take it well. On small lenses trim a little from the outside edge.
Ski gogglesBEST
Ski and snowboard goggles. The largest, flattest lens. Apply indoors and warm, one per eye, centred on the pupil. Very steep toric lenses may crease.
Swim gogglesBEST
Swim goggles and snorkel masks. Small and mostly flat, close to ideal. Dry the inside first, then a little water.
TacticalGOOD
Tactical and airsoft eyewear. Works on the inside of most flat and mildly curved lenses. It does not change any safety or impact rating.
Moto visorsGOOD
Motorcycle visors. Place it on your line of sight, not the visor centre: put the helmet on and mark the spot first.
Photo on the way Sport wrapsCARE
Sport and cycling wraps. Mild wraps work. Deep wraps can crease the flat silicone. Use the flattest part over your line of sight and less water. Try one pack first.
Photo on the way ShieldsCARE
Single lens shields. Fits where the shield is gently curved in front of each eye. Steep sections can lift at the edge.
Photo on the way VR headsetsCARE
VR headsets. Trim it to a circle that covers the sweet spot of the headset lens.

Compatibility
It fits any smooth inner lens surface with about 45 by 26 mm of room. Some eyewear is easier than others, so each type gets an honest label.
| Eyewear | Label | What to know |
|---|---|---|
| Sunglasses, flat or mildly curved | BEST | The easiest fit. Dark and gradient tints hide the edge. |
| Ski and snowboard goggles | BEST | The largest, flattest lens. Apply indoors and warm. Steep toric lenses can wrinkle the patch. |
| Swim goggles | GOOD | Dry the inside first. Small lenses may need a trim. |
| Snorkel and dive masks | GOOD | Dry the glass, press firmly, check before you go in. A mask flood can move it. |
| Motorcycle visors | GOOD | Place it on your line of sight, not the centre of the visor. Test at a standstill. |
| Airsoft and paintball masks | GOOD | Inside the lens only. The patch adds your power. It adds no protection. |
| Cycling and running wraps | CARE | Deep wraps can crease the patch or lift the edge. Try one pair first. Trimming helps. |
| VR headsets | CARE | Small, curved, coated lenses. Trim to fit and test on a lens protector first. |
| Safety glasses | CARE | For the bench and the hobby. The rating of the glasses stays the maker's. |
Tint and the edge
On dark tints the edge of the patch is nearly invisible from the front. On light, clear or mirrored lenses it can catch the light. If the look matters, start with a dark lens.
Curve
The patch is flat and takes the curve of the lens. Flat and mildly curved lenses are where it works best. On a deep wrap, use the flattest part of the lens that still covers your line of sight, and use less water so it grips sooner.
Small lenses
Silicone cuts cleanly with sharp scissors. Trim a little at a time from the outside edge and keep the shape smooth. Get the power right first: a trimmed lens cannot be swapped under the wrong power guarantee.
The honest part
- Sphere only. Astigmatism (CYL) is not corrected.
- It covers your line of sight, not the whole lens.
- The edge is nearly invisible on dark tints. On light or mirrored tints it can show.
- Deep wraps can crease the patch or lift it at the edge.
- unblur is a vision accessory. It is not a prescription service, not a medical device and not a substitute for an eye exam.
Fit questions
Does it work on curved or wrap lenses?
Flat and mildly curved lenses: yes, and that is where it works best. Heavy wrap lenses, the deep sport wraps that curve hard around the face: sometimes, and sometimes the silicone wrinkles because the patch is flat and the lens is not. This is the single most common complaint in this whole product category and we are not going to pretend otherwise. If your only pair is a deep wrap, order one pack and try it before you buy three. Two things that help: apply to the flattest part of the lens you can while still covering your line of sight, and use less water so the patch grips before it has a chance to lift at the edges.
Will people see it from outside?
On dark tinted sunglasses, no, in normal use. The patch is clear and sits behind the tint, and from a conversational distance there is nothing to see. On light tinted, clear or mirrored lenses, the edge can catch the light at certain angles and a person standing close may notice a faint outline. On a clear lens in bright direct sun it is most visible. If the fashion side matters to you, start with a dark lens.
Can I cut it to fit?
Yes. Silicone cuts cleanly with sharp scissors, and for small frames, narrow fashion lenses and headset lenses that is the way to make it fit. Cut a little at a time from the outside edge, keep the shape smooth, and never cut into the middle: the centre is the part you actually look through. A rough or jagged cut edge lifts more easily, so take one more small pass rather than one big one. Once you cut it we cannot swap it under the wrong power guarantee, so get the power right first and cut second.

Asked before you ask.
Fit
Will it fit my sunglasses?
If the inside of the lens has about 45 by 26 mm of smooth surface, yes. Flat and mildly curved lenses are easiest; ski and swim goggles fit well; deep sport wraps can crease, so try one pack first and use the flattest part over your line of sight.
Can people see it?
On dark tinted sunglasses, no, in normal use: the patch is clear and sits behind the tint, with at most an extremely faint hairline for a careful eye. On light, clear or mirrored lenses the edge can catch the light at some angles.
Does it correct astigmatism?
No. unblur corrects sphere only. With a CYL of 0.75 or less most people find sphere alone is fine for sunglasses; above that, expect softer edges than your own glasses.
Wear and care
How long does it last?
It is reusable: peel it off, rinse it, put it back or move it to the next pair. A thin film of water holds it. If it loosens after a long day in wind or heat, a drop of water and a press brings it back. We do not print a number of uses until we have tested it.
Can I use it in the pool or the sea?
Yes, inside swim goggles and snorkel masks: dry the inside first, then a little water. Rinse off salt and chlorine the same day.
How do I clean it?
Cool water and a drop of plain dish soap, fingertips only, rinse well and air dry. No alcohol, lens spray, acetone or hot water: they haze silicone.
