You must go through the contact lens prescription process if you want contact lenses. Contact lenses offer advantages over glasses, appealing to people with diverse lifestyles and vision needs. They provide greater freedom of movement and a natural field of vision, making them ideal for sports and active lifestyles. Contact lenses offer sharper vision and can correct refractive errors like myopia, hyperopia, astigmatism, and presbyopia.
Cosmetically, contact lenses allow wearers to enhance or change their eye colour discreetly. They’re also designed for comfort, with custom-fit options, ensuring a personalised and comfortable wearing experience. People often choose contact lenses for their practicality and safety in certain occupations and activities, such as sports and water-related pursuits.
Psychologically, contact lenses can boost confidence and self-image, particularly in social or professional settings where glasses may carry a stigma. Ultimately, choosing contact lenses is based on factors such as lifestyle, comfort, visual correction needs, and personal preferences for appearance and convenience. Many people find contact lenses offer greater flexibility and comfort in their daily lives compared to traditional eyeglasses.
Steps Involved In A Contact Lens Prescription
Getting a contact lens prescription involves several steps to ensure the lenses fit correctly, provide clear vision, and are safe for the eyes. Here’s an overview of the process:
1. Comprehensive Eye Exam
A comprehensive eye exam is the foundation of a contact lens prescription. It involves several tests to assess your eye health and vision:
- Visual Acuity Test: As part of the Visual Acuity Test, you must read from a Snellen chart, which measures your ability to see clearly at different distances. This test helps identify if you need corrective lenses.
- Refraction Test: Using a phoropter and retinoscope, the optometrist determines the exact prescription needed to correct refractive errors like myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. This test involves looking through different lens combinations to find the clearest vision.
- Eye Health Evaluation: The optometrist will examine the front and back of your eyes. This can include:
- Slit-Lamp Examination: A microscope with a bright light is used to examine the structures of your eye under high magnification, checking for abnormalities or diseases.
- Intraocular Pressure Measurement: Often done with a tonometer, this test measures the pressure inside your eyes, which is crucial for diagnosing glaucoma.
- Retinal Examination: Using tools like an ophthalmoscope, the optometrist checks the retina and optic nerve for signs of diseases such as diabetic retinopathy or macular degeneration.
2. Contact Lens Fitting
Once your eye health and vision prescription are determined, the next step is a contact lens fitting:
- Corneal Measurements: We measure the curvature of your cornea using a keratometer or corneal topographer. These measurements ensure the contact lens fits well on your eye’s surface and provides the best vision correction.
- Pupil and Iris Size Measurements: Accurate measurements of your pupil and iris help in selecting the correct size of contact lenses. This ensures that the lenses align properly with your eyes and remain stable.
- Tear Film Evaluation: A tear film assessment determines the quantity and quality of your tears. This is important because a healthy tear film is necessary to keep the contact lenses comfortable and to prevent dryness.
3. Trial Lenses
Based on the measurements and initial prescription, the optometrist will select a pair of trial lenses:
- Insertion and Removal Training: You’ll be taught how to insert and remove the contact lenses properly. This training includes hygiene practices to avoid eye infections.
- Evaluation of Fit and Comfort: After you’ve worn the trial lenses briefly, the optometrist will check their fit and comfort. They will look for signs of poor fitting, such as excessive movement, discomfort, or redness.
- Vision Check: The optometrist will also check your vision with the trial lenses to ensure that the prescription provides clear and accurate vision.
4. Prescription
Once the right fit and prescription is confirmed, the optometrist will provide you with a contact lens prescription, which includes:
- Lens Material and Brand: We make specific recommendations based on your eye health and lifestyle. Different materials offer benefits like better oxygen permeability, which is essential for eye health.
- Base Curve (BC): Indicates the curvature of the lens to match the shape of your cornea, ensuring a snug and comfortable fit.
- Power (Sphere, SPH): The lens strength needed to correct your vision, measured in diopters. Negative values correct myopia, while positive values correct hyperopia.
- Cylinder (CYL) and Axis: If you have astigmatism, these values correct it. The cylinder indicates the lens power needed to correct astigmatism, and the axis specifies the lens orientation.
- Addition (ADD): For multifocal lenses, this value indicates the additional power needed for near-vision tasks, such as reading.
- Replacement Schedule: Specifies how often you should replace your lenses (daily, bi-weekly, monthly).
- Wearing Schedule: Guidelines on how long you can wear your lenses daily (daily wear, extended wear).
5. Follow-up Visits
Follow-up visits are crucial to ensure the lenses are performing well and not causing any problems:
- Initial Follow-Up: Typically, within a week or two after wearing the lenses, the optometrist will check your vision, the fit of the lenses, and the health of your eyes.
- Ongoing Monitoring: Regular check-ups, usually every six months to a year, to monitor your eye health and update your prescription as needed. Any issues with discomfort, vision changes, or eye health will be addressed during these visits.
6. Ongoing Care
Proper care and maintenance of your contact lenses and eyes are essential:
- Lens Cleaning and Disinfection: Daily cleaning and disinfection routines to remove debris and prevent infections. This involves using appropriate lens solutions and following hygiene practices.
- Lens Storage: Proper storage in a clean, dry case with fresh solution to maintain lens hygiene.
- Replacement Adherence: Following the recommended replacement schedule to avoid over-wearing lenses can lead to complications.
- Eye Health Monitoring: Regular eye exams to monitor for changes in vision or eye health, ensuring your lenses remain safe and effective.
By following these detailed steps, your eye care professional will ensure that you receive the most suitable contact lenses for your vision and eye health while educating you on the proper use and care to maintain healthy eyes.
