A clever friend of mine :doctor: developed a Underwater Magnifying Glass . See the Underwater Magnifying Glass homepage.
Normal magnifying glasses do not work underwater :nono:, since the refraction index of glass is almost equal to the refraction index of water. Magnifying power is lost.
My friend found a solution :hehe: and now makes and sells these magnifying glasses. Here a lot of my diving association members use the glass for studying underwater life on the square inch. It works well.
Does anybody have seen similar developments?
