Heath studied optometry at The University of Melbourne, completing his bachelor degree in 1994 and graduating with first class honours in 1995. In his final year he was awarded the Allergan prize for contact lens practice excellence. He then went on to complete a postgraduate certificate to endorse therapeutic prescriptions.
Initially Heath practiced in Melbourne and then country Victoria before moving to Hobart in 1999. Since moving to Hobart he has focused on fitting complicated contact lenses, including keratoconic, paediatric and orthokeratology lenses, as well as general optometrical practice.
Heath is as a volunteer director and past president of the Australian Cornea and Contact Lens Society, an organization that promotes better understanding of contact lenses amongst his profession as well as supporting novel research and development. He also volunteers regularly for Rowing Tasmania as a rescue boat driver as well as Safety Officer at his daughter’s rowing club. In the little time he has left for hobbies, he enjoys building, fly-fishing, wind surfing, cycling and diving.
