Restricting the rhymes in a poem to those that satisfy the eye but not the ear.
Eye rhyme is a similarity in spelling between words that are pronounced differently and hence, not an auditory rhyme. Some examples are slaughter and laughter.
Many older English poems, particularly those written in Middle English or written in The Renaissance, contain rhymes that were originally true or full rhymes, but as read by modern readers they are now eye rhymes because of shifts in pronunciation. An example is prove and love.
Other eye rhymes:
* sew : blew
* brow : crow
* said : laid
* read : dead (however, in the past tense read does rhyme with dead)
