Understanding this correction
The correction extends across the viewing lens, rather than forming a separate lower gauge-reading segment. These premade spherical lenses do not reproduce cylinder, axis or prism values from a custom spectacle prescription. Ask your optometrist to confirm whether the available powers are appropriate for each eye.
Select both lens entries carefully, including left/right where the lens model uses different sides. A lens name or colour choice does not determine the correct strength. If your needs fall outside the available options, contact our team about a custom prescription mask.
Follow the mask manufacturer’s lens-fitting instructions or ask our team to arrange fitting. Check the completed mask seal and vision before entering the water.
Mask fit and choosing a gift
Face width, shape and nose-pocket comfort matter more than a general age or gender label. Keep hair clear of the skirt and check for an even seal without pressure around the brow or cheeks. Use light strap tension. For a gift, confirm the recipient’s fitting needs before selecting lens powers or fin sizes; our Hallam team can help compare options.
Lens care
Rinse with fresh water, dry in the shade and protect the lenses in a case. Use only cleaners and anti-fog treatments suitable for the installed corrective lenses. Avoid abrasive cleaners and flame treatments.
