good
vision whether in the water or out of it. In fact due to the tiny central
lens of 200 dioptres, the fall in the eye/s acuity when it is immersed
in an element with an optical density similar to that of the human cornea
is balanced out.
This lens, being very small indeed (about 2mm) does not cover all the
field of vision, thus allowing for focussed vision across the uncovered
area when out of the water.
Those
interested in acquiring "Apnea" lenses can contact me by telephone
or better, via e mail, filling in the appropriate
FORM.
