A convenient option available for individuals with certain eye issues is the installation of prescription lenses directly into your mask. There are both nearsighted and gauge reader corrective lenses easily installed into certain quality masks. All that’s needed is your correct and current eye prescription, it’s recommended to get the doctor’s official prescription. Once you have the correct prescription you can purchase prescription lenses which are installed into your mask or choose to have bonded lenses put in. Installed lenses are non-custom prescription lenses which are put in place of normal mask lenses. Custom-made bonded lenses are precise and can have your exact prescription put on the lens and may be necessary if you have an astigmatism. Bonded lenses are the exact same as having your personal glasses inside your mask lens, which makes for a comfortable and familiar feeling while snorkeling!
