Stick-On Bifocal Description

See the small stuff. Keep your view of the reef.

Reading glasses don't come with you into the water. These do. Ultra thin reading lenses stick to the inside of your mask and turn it into a bifocal in minutes. Look ahead and the reef stays exactly as sharp as before. Glance down and your watch, dive computer or camera screen comes into focus. No squinting, no guessing, no lifting your head to check. Just get on with enjoying the water.

Made for divers and snorkellers

Read your screens. Dive computer, gauges, camera or phone in its waterproof case. A quick glance down and it's readable.

Keep track of time. Boat pickup, tide window or just making sure you don't overstay. Check your watch without guessing.

Nail your photos. Check your settings and your shots in the water instead of finding out later.

Spot the tiny details. Nudibranchs, shrimp and small creatures in the shallows are easy to miss when close up is a blur. Now you can see them.

Your view stays clear. At just 0.52mm thin, it sits low and flush against the glass, so your forward view isn't blocked.

Keep the mask you love. No need for a new mask. Just add reading power to the one that already fits.

Fitted in minutes, no mess. No glue, no water. Clean the glass, place it with tweezers, press, done.

Buying a new mask? Add a pair. Fit them once your mask is prepped and it's ready for its first trip.

Fits most masks with flat glass lenses. Sold as a pair.

How to Fit

How to fit

  1. Clean the inside of the mask lens thoroughly. New masks have a factory coating on the glass that must be removed first. Follow your mask's preparation instructions before fitting. Then wipe with an alcohol wipe to remove any grease, fingerprints or anti fog residue.
  2. Make sure the reading lens itself is clean and free of dust.
  3. Put the mask on and look down to where you'd hold your watch, computer or camera. That's where the lens goes.
  4. Using tweezers, place it with the curved side against the glass. Press evenly for about 4 seconds, smoothing out any bubbles from the centre outward.
  5. Test it in the pool or shallow water before your first proper dive or snorkel.

For best results, get the position right early. Repeated removal will reduce the grip over time.

Choosing your strength

If your prescription has an ADD (you wear bifocals or varifocals), choose the strength that matches your ADD. If you don't have an ADD, match your everyday reading glasses.

Don't see your exact ADD? Choose the next strength down. For example, if your ADD is +2.25, choose +2.00. A slightly weaker lens still gives you a comfortable reading distance, while one that's too strong makes your focus zone uncomfortably close.
