Contact Lenses Fitting
Contact lenses are a great alternative to eye glasses for any age. They come in a wide variety of designs, materials, sizes, and colours. However, because contacts lenses are inserted into the eye, they are considered a medical device, therefore it is important to have a professional contact lenses fitting to find the most appropriate contact lenses for your comfort, vision needs, and eye health. Sometimes the contact lenses power may be different from what is specified for eye glasses to account for the way contact lenses fit closer to the eye than glasses.
Contact lenses fitting includes the following:
- You will be asked questions about your health, occupation and lifestyle, which will help Markham Optometrist, Dr. Jessica Nhan recommend the most appropriate type of contact lenses, contact lenses material and replacement frequency for you
- Dr. Jessica Nhan will then perform tests to examine the anterior surface of your eye, the shape and size of your cornea, and your tear film quality, as well as your eyelid position and movement
- Dr. Jessica Nhan will then select the appropriate initial diagnostic contact lenses and evaluate the fit and visual performance of the contact lenses on your eyes
- You may need to try on more than one pair of contact lenses to identify which lenses are the best for you
- If you are a first time wearer or are new to a type of contact lenses, instructions for contact lenses insertion and removal, hygiene and wearing time will be provided
- After the initial contact lenses exam, you will be given trials and solution/contact lenses case if needed, to try at home
- Before purchasing contact lenses, you may require one or more follow‐up visits during the adaptation period to assess contact lenses performance and ensure that your eyes are adapting normally to the contact lenses
Improperly fitted contact lenses may cause blurred vision, eye strain, eye pain, headaches or redness and swelling of the eye that can range from mild to severe. The most serious complications include infection and corneal ulcer, which can develop quickly and can lead to irreversible vision loss if not treated appropriately.
