If you surface you could always skip the polish and leave the lens frosted. Or you could use a bangerter filter and apply it to a plano lens.

get the finest sandpaper you can find and just sand the back side of the lens.

As CMe4 says, if you're using plastic or poly you can create the frost yourself by using a very very fine sandpaper, or, as Harry says, you can ask the lab to surface a plano lens and skip the fining/polishing step. I think the latter approach yields a better-looking product.

The function is to occlude the eye. It lets light in but no discernible image.

A while back, one could order a frosted or pebbled lens (in glass -- that'll tell you how long ago it was!) as a stock item. I don't know if that's true today.

Would use a ballance lens something approching the size weight and configuration of the the good eye and frost. Rx doesn't matter in a frosted lens but the weight imballance, frame/lens cosmetics will be horrible with Plano on one side and this type Rx on the other. Even the prescriber should be smart enough to know this.

Ha! Wouldn't count on that considering how many post-cataract patients with similar rx's to the one in question here are sent in to have a lens removed 'cause the Dokter said to take it out'.

And BTW, I once saw a lab invoice with an extra charge for providing a frosted lens- isn't that interesting- guess they felt there was extra work involved in removing the lens from the generator prior to the finishing cycle! (Yes we were credited the xtra charge once we brought it to their attention).
