Bonded Corrective Lenses

A full field view also cannot be guaranteed because the lenses may not be cut in the exact same shape as the mask lens.

Custom Prescription Lenses

The good thing about this type is the fact that the mask lens is replaced with a piece of glass that is personalized according to your prescription.

It is also a lot lighter than the bonded prescription and provides a wide, full view of the underwater world.

Drop-In Lens

Think about ease of use and trouble-free replacement of one lens to another. The good thing is that you can purchase the drop-in lens by yourself and carry out the removal and replacement on your own. Take note, however, that this will not work for you well if you have strong prescriptions or if you suffer from astigmatism. Nevertheless if you are interested in this type, ask about the bifocal options from your supplier.

There you have it, your guide to purchasing the perfect dive mask for you. Just remember that before actually buying one, you have to visit your eye doctor to have your sight examined. Having your vision checked will help you ensure that your prescription is accurate. Happy shopping and enjoy your next underwater adventure
