Hydrotac® lenses measure 3cm along the flat edge and are 1.6cm deep.

They cling like magic!
Hydrotac® lenses are soft, pliable plastic lenses shaped in a half moon. This ultra thin design clings to the inside of your sunglasses, safety glasses or diving goggles through molecular attraction. No adhesives are needed.

Fit any Shape or Style!
Whether you wear traditional sunglasses, polarized fishing glasses, narrow lenses or trendy wraparounds, Hydrotac® Lenses are designed to fit any style. Each lens is optically correct from edge to edge, providing distortion free magnification.

Removable and re-usable!
Hydrotac®Lenses leave no residue. They are instantly and easily installed with water and may be removed and reinstalled at any time.

They're invisible!
One of the best features is the fit so snugly to the inside surface of your sunglasses that when someone is looking at you, they are undetectable from the outside. You will enjoy the benefit of magnification and no will even know you have them on.

Hydrotac® Lenses- soft, tiny removable lenses that can change any style of sunglasses or safety glasses in to an instant set of bifocal readers at a fraction of the cost of prescription bifocals.
