3M Press-On Optics are the simple, inexpensive and fast way to add vision correction to your dive mask.  Ideal for both diving and snorkeling.   

Apply the Press-On™ Optics to the inside of the mask. The lenses attach by hydrostatic adhesion. The 2 1/2" diameter round lens is removable and trimmable to any shape. The lens can be cut in 1/2 and combined with a second lens in the correct strength to create a bifocal mask.

Attachment is easy. Wash your mask to remove any grease, soil or anti-fog treatment. Submerge the mask and lenses in water. Position and press dry.

The 3M lens provde spherical correction only and provides good vision for most wearers.  If you have astigmatism - cylinder correction - greater than +/-1.5D, you should consider a full prescription mask.  We will calcualte the best available sphere correction from your prescription.   
 
The price is for a single lenses.  If both eyes require the same correction, a single lens cut in 1/2 will often provide sufficient vision area.
