The Video

The I Didn’t Know That team visit a medical laboratory to see how artificial eyeballs are made. Every single eye is made by hand and precisely tailored to its wearer. This short video is an interesting introduction to this strange world but maybe not one for the squeamish!

Level and Language Focus

The narration is fairly slow but the vocabulary is very technical in places. Vocabulary like varnish, acrylic, mould and fibres are on the technical side but not completely useless in general life. With the downloadable transcript (below) you could use this video with levels intermediate and upper intermediate.

The video is full of examples of the passive voice (passive tense) and is ideal if you are teaching this grammar point.

The video could be especially interesting for young learners due to the content but it is equally engaging for adults too.
