Testing is required, beyond the scope of a routine eye health examination and issuance of an eyeglass prescription, for cosmetic contact lenses.
For new contact lens wearers, the optometrist must evaluate and record the contact lens performance on the eye. The patient must be taught contact lens placement, removal, care and be given a wearing schedule. Typically, the recommended solutions and a contact lens case are provided. At least a one-week follow-up is required before the contact lens prescription is released.
For current contact lens wearers, the optometrist must evaluate and record the contact lens performance, condition and associated vision prior to issuing a new prescription.
Medical eye health problems such as Keratoconus (odd shaped corneas) and Anisometropia (large prescription differences between the eyes) may require many addition visits and special contact lens constructions.
