Tried my new hydrophobic coated lenses for the first time today, in small 3-4 foot waves, very light wind. The first session EVER without lens fogging, of my polarized prescription goggles!!! Those sprays and drops and waxes do not hold up to repeated dunking in salt water.
Frames available from China with impact nose piece and elastic strap, for $9.99 USD. Lenses $100 to $150 or more, depending on the vendor. Sports polycarbonate, polarized photo gray, single vision distance prescription.
Work done by Sports Optical in Denver, Colorado, contact: Andrew. One day or even same day turnaround, cost $50 USD for the coating per pair.
Similar lab services available in UK and probably AU, but call first.
