Adlens is about to introduce a pair of inexpensive eyeglasses with both celebrity cachet and a technology that lets you adjust the prescription by just turning a knob.
Its John Lennon Collection features glasses in the round style favored by Mr. Lennon (or Harry Potter, if you don’t know who Mr. Lennon is) with a variable lens that can be adjusted for near, intermediate or distant sight. The sizable knobs that adjust the lenses are removable, but you would have to keep them handy if you often want to change prescriptions.
The glasses, which become available in April at a price of $80, are just one of several similar designs available from other companies, but Adlens claims its design has a greater range of adjustability than those of its competitors.
