An important piece of information missing from this press release, which is only fair for consumers to be made aware of, is that the advertised strength (+16 diopters) is only accurate when using it in air, since it doesn't seem to be an air-sealed lens system (correct me if I'm wrong). If this is true, then when used underwater, this lens will lose approximately 65% of its power, making it closer to a +5 diopter lens.
