Your lifestyle, occupation and hobbies may influence the tests used and the lenses that the optometrist prescribes and the type of lens and frame that are dispensed. Certain occupations have specific requirements e.g. the armed forces. Your optometrist can also suggest what type of lenses may help you in your working life e.g. a musician might need a specific prescription for reading music, or a dentist might need a closer working distance than would be achieved with normal reading spectacles.
