Find your closest preset lens power
Use the distance prescription from your optometrist. Enter one eye or both eyes. Leave the other eye blank if you only need one lens. Results are a guide for preset sphere-only lenses, not a replacement for an eye-care professional's recommendation.
Enter SPH and CYL with a + or − sign, or choose the sign beside each number.
Our custom lenses can be made for your full prescription, including astigmatism or reading correction where suitable.
Explore our custom prescription dive masks →We estimate spherical equivalent as SPH + CYL ÷ 2, then show the closest 0.50 D step from ±1.00 D. AXIS helps describe astigmatism; ADD and prism are not corrected by a distance-only preset sphere lens. A suggested preset may improve distance vision without matching a full prescription. Exact powers and stock differ between masks; check the lens choices above before ordering. If the prescription is for reading only, use the custom lens service or ask your optometrist.

Choose the correct left or right lens and a listed power from −1.0 to −6.0 in 0.5-dioptre steps. A complete twin-lens mask needs two lenses, selected for each eye.
Which Cressi masks use these negative lenses?
