Roger,

We use this eye model with the elastic lens as also sold by 3B
Scientific:

http://www.a3bs.com/Functional-Eye-W16002,p_83_113_875_4129.html?initOptionReferer=1

It's a nice device and it comes with correction lenses. A while back
one of our professors broke the +1 lens and I had to get a
replacement. I got it from 3B but it sure was not cheap. I still
figured that it was worth to get the original lens in order to make
sure it fits with the model and it did.

Don't know if this information helps you.

Regards

Urs
