Deep See Corrective Diopter Lens for Clarity Mask

If you're a diver or snorkler who wears glasses, drop in diopter lenses can be an inexpensive alternative to custom-ground prescription corrective lenses you can purchase diopter lenses for your scuba or snorkeling mask

Your Rx for your eyeglass will help determine the power correction you will need.

  SPH CYL AXIS PRISM Add PD
OS -2.50 075 136   +2.00 31.5
OD -3.00 100 025   +2.00 31.5

 

What does all this mean:

  • OS - Left Eye
  • OD - Right Eye
  • SPH (Sphere): The strength of your Rx expressed in diopters.  Pay close attention to the plus (+) or minus (-) signs.
  • CYL (Cylinder): The numbers show the strength of your astigmatism. If you see SPH or Sphere then you do not have an astigmatism.
  • AXIS: Rotation to correct your astigmatism
  • ADD: If you have a bifocal this is the amount of power to be added
  • PD (Pupillary Distance): Measurement in mm between the center of your pupils.  There are 2 common ways it can be written - PD:31.5/31.5 (like show above) or PD: 63

Ordering Tips:

  • SPH: If you have a quarter diopter (.25) then we recommend you go down and a three quarter diopter (.75) then go up.  For example: -2.75 should go to -3.0.  Pay close attention to the plus (+) or minus (-) signs.
  • CYL & AXIS:  If your Rx shows you have an astigmatism then please contact us for options as these lenses do not correct for astigmatism.

Reading Glasses - If you only need vision correction for reading then we recommend Bifocal / Gauge Reader Lenses
