These Mares Prescription Lenses will help you see more clearly while snorkelling or diving if you need help with short sightedness - you have a minus prescription.  These lenses are specifically for the Mares Marea snorkelling mask.

The lenses are available to buy individually so you will need to order 2 lenses - a left and a right lens according to your requirements.  

These Mares 'off-the-shelf' Mares corrective lenses are available in 0.5increments for your left and Right eye for short sightedness, minus prescription only.  The lenses do not compensate for astigmatism nor correct any other requirements of your prescription.  These Mares corrective vision lenses are specifically for use with the Mares Marea mask.
