Turn any glasses into bifocals instantly... just add water... and some Optx lenses! Patented Optx magnifying lenses can make it easier to see things up close and you dont need a prescription... or even new glasses! Just dampen the lenses and apply them to any glasses, including sunglasses. You can peel them off at any time and reuse them elsewhere. Includes storage case. Glasses not included. Please note, Optx lenses are not intended to replace any prescribed corrective lenses or examinations by an eye care professional.
