Historical information

Model eyes were used by students to practise skills of ophthalmoscopy and retinoscopy. This item shows more variety of fundus view and refractive state than most.

This fine example is preserved in excellent condition, perhaps through lack of use. It is the most complex of the five model eyes in the collection.
