Choosing your lens
Ask your optometrist to confirm the appropriate gauge-reading power for each eye before ordering. These lenses do not reproduce cylinder, axis or prism values from a custom spectacle prescription. Do not assume a gauge reader should match the Sphere number on your everyday glasses prescription.
Each lens is sold individually; a complete twin-lens mask normally needs two. Choose the correct left or right version and power for each position.
Fitting and care
Confirm the mask model before ordering and follow the manufacturer’s fitting instructions. Ask our team to arrange fitting if you are unfamiliar with the frame. Rinse with fresh water and use only cleaning products suitable for the fitted lenses.
