I never want my eyeglasses to be that thick again. Decades ago I switched away from glasses to contact lenses because thinner lenses were either not possible or not affordable.
In more recent years I’ve switched back so my corrective lenses can serve all purposes (distance, reading, and sunglasses - with photo-gray lenses). There is also an extraordinary dispensary nearby with frames that use small lenses and fit an adult’s head.
Now my thickest lens edge is just under 4.5 mm (with a -9.75/-9.5 prescription). That’s around .175 inches.
