Are lenticular and progressive lenses the same? If not, how are they different?

In lenticulars to limit the great thickness and weight that high-power lenses would otherwise require, all the power of the lens is concentrated in a small area in the centre. In appearance, such a lens is often described as resembling a fried egg: a hemisphere atop a flat surface.

Lenticulars are single vision lenses with just the one power in them concentrated in the centre as stated above.

Progressive lenses are varifocals, they are characterised by a gradient of increasing lens power, added to the wearer's correction for the other refractive errors. The gradient starts at a minimum, or no addition power, at the top of the lens and reaches a maximum addition power, magnification, at the bottom of the lens.

Edit - Oooooooooooo Footprint honey you should see how many I've made over the past six years at the opticians I work for.. Lentics gotta love them.

Lenticular Lenses

There is no resemblance at all.

Progressive lenses are graduated power bifocal lenses, or varifocals is another term. Millions wear them today

Lenticular lenses used to be used for post cataract patients who needed very high plus powers before implants came into being. Lenticulars were available in regular lined bifocals or in single vision form. They are rarely seen anymore , except for older folks who had the surgery before 1975 or so.

Very interested to hear the answers to this as well

Sorry but I don't know about this
