Optx 20/20 Hydrotac stick on lenses allow you to convert spectacles, sunglasses, safety glasses and diving masks into reading glasses. Hydrotac lenses adhere using water and can be easily removed and reused to provide reading magnification. The following powers are available:
+1.25, +1.50, +1.75, +2.00, +2.50 and +3.00D power.
The new lenses are manufactured to the same high standards as before but are now supplied in attractive new packaging with easy to understand instructions.
Hydrotac lenses can be easily trimed using sharp scissors and we recommend that only the bottom section is trimmed. The stick on lenses can also be attached to the upper part of the spectacle lens if magnification is required whilst looking up, for example in certain occupations.
