SPH -2.50, two pairs

UNBLUR lens patches
Your sunglasses never had your prescription. Now they do: wet it, press it, wear it.
Without unblur
Both patches in a pack are the same power. Between two numbers, take the weaker one. Sphere only.
One pack per pair you wear.
- Every pair you own needs one. A patch stays in its pair. Skip one and that pair stays soft.
- One for the car. The pair that lives in the glovebox is ready when you are.
- Your goggles need their own. Ski, swim or moto gear lives in a different bag.
- A spare for the trip. Lose one on holiday and the rest of the trip goes soft.
- Less per pair. $39 for one, $34.50 each for two, about $31.67 each for three.
- Two identical patches, one power
- The frosted case they live in
- A press seal pouch, printed with your SPH

Every worry, answered.
Fit
What if it does not fit my sunglasses?
It fits if the inside of the lens has about 45 by 26 mm of smooth surface. 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.
Will people notice it?
Not on dark tints, 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.
I have astigmatism. Will it work?
Partly, and we would rather tell you now. unblur carries the sphere (SPH) power 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
What if it stops sticking?
A drop of water and a press brings it back. A thin film of water holds it, and it is reusable: peel it off, rinse it, put it back or move it to the next pair. We do not print a number of uses until we have tested it.
Will it survive 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.
What if it gets dirty?
It washes clean: 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.
