Do I need a sight test if I've been for a contact lens check-up?
If you don't have a current prescription, yes. In a contact lens check-up, the optician examines the front surface of the eye which is in contact with the lens, checks the quality of vision wearing the prescribed lenses and makes sure that the lenses fit properly.A comprehensive eye examination measures your sight and determines the exact prescription required to give you clear vision. It also includes an examination of the eye itself, to screen for conditions like glaucoma and cataract. The eye examination is a valuable health check; indications of other medical conditions, such as high blood pressure and diabetes, can also be found.
