Contact lenses are regarded as medical devices requiring a prescription, even if used solely for cosmetic purposes. During your comprehensive eye exam and contact lens fitting, the optometrist will determine if contact lenses are right for you. In addition to the prescription, you'll receive the lenses, lens care kits, individual care and wear instructions, and instructions for follow-up visits.
Typically, contact lens prescriptions expire after one year, though optometrists can adjust this timeframe based on individual needs. It's important to note that while prescriptions for both glasses and contact lenses may appear similar, they are not interchangeable due to the distinct nature of each device. Contact lenses vary in material and size, affecting comfort and eye health differently—some may suit a wearer perfectly, while others could cause discomfort or even lead to eye health issues. Therefore, acquiring a contact lens prescription entails more than just determining the optical strength needed to correct vision problems like myopia, hyperopia, or astigmatism; it requires a comprehensive understanding of the wearer's specific eye health requirements.
During a contact lens fitting, an optometrist assesses the lenses' fit, position, and movement on the eye, conducting further tests as needed. A subsequent check-up focuses on identifying any issues stemming from lens use. Patients also receive a trial pair of lenses to evaluate comfort and vision quality over a designated period. The use of contact lenses carries risks such as eye infections, corneal ulcers, and conjunctivitis. However, many potential complications can be mitigated through correct lens handling and adherence to recommended wearing schedules. Ensuring the proper care and usage of contact lenses is crucial for eye health. For any questions or concerns regarding lens use, consulting with an optometrist is advised.
