"Not only a superb entry but also loads of links "

Yes but... some of the links, though to interesting entries, have only tenuous connections to the topic. I refer to the link to superellipses (my entry ) from a mention of ellipses. Admittedly you'll find useful mention of centres of curvature in that entry but to be fair superellipses have little to do with lenses.

Impressive collection of links anyway

Pimms

As has been mentioned previously in regards to this entry, the point in adding internal links in h2g2 entries is not (and never has been) solely to add more information about the subject of the entry. Rather, it goes back to the concept of hypertext -- the same concept is used, by the way, for both Wikipedia and the online Enclyopedia Britannica.

Yes, I did have this conversation with Mikey whilst it was going throught the Editorial process.

talking of lenses when tears are filled in eyes they can read very small letters sometimes

I keep saying I do not need them! "

Under these circumstancesc I usually peer through a 'pinhole'created from my two forefingers and thumbs. I can read a board from the back of a lecture theatre like this!
