Eye doctor in Toronto will conduct specialized tests to determine your suitability for contact lenses. These exams are different from routine ones that are conducted in relation to eyeglasses. Those who are interested in wearing contacts or simply want prescription updates for their existing ones have to schedule appointments with optometrists.
This comprehensive process tests visual acuity using eye charts, determines optic health, and helps correct refractive errors through prescription eye wear. When you visit your eye doctor in Toronto,they will ask you several questions to understand your general health and preferences. For example, you may choose to wear colored lenses to change original color of your eyes. Are you going to wear your contacts overnight? Would you like to have options like daily disposables? You must communicate your needs to the optometrist and seek desired help.
Fitting of Contact Lenses
Your optometrist will take accurate measurements to ensure that the contacts you finally wear are the best fit. Too steep or flat curvatures will lead to irritation, discomfort, and even eye damage.
• Cornea Measurement: Device used for this is tetrameter, and it measures front clear surface of your eyes. For this, it analyses reflection of light from cornea. Resultant measurements will help eye doctor in Toronto to decide proper size and curve of the contacts for you. For precise and most accurate details, corneal topography or computerized measurements are performed. Presence of irregular eye surface due to astigmatism means that you will require specially designed lenses, the tonic contacts. Different versions of these lenses are available such as colored, multi focal, disposable, and extended wear.
• Evaluation of Tear Film: Eye doctor in Toronto performs this test to ensure perfect contact lens fit. First, they will insert small paper strips underneath the lower eyelid. They will then tell you to close your eyes for at least 5 minutes before removing paper. Moistened length of paper helps in evaluation of tear production. This in turn helps to determine presence of dry eyes. For this, your optometrist may additionally use fluoresce in dye test where they apply dye to tear layer using moistened strip of paper or eye drops. After this, they will note time taken for evaporation of tear. This is important because contact lenses are not suitable for excessively dry eyes. Modern doctors may prescribe silicon hydrogen in such cases.
• Iris/Pupil Measurement: This is a simple measurement; and for this, modern eye doctor in Toronto uses automated scales for faster and accurate results. Your doctor will now be able to fit you with proper size contact lenses that will enhance your appearance. Highly specialized, these instruments are capable of measuring both vertical and horizontal eye diameters simultaneously.
With comprehensive tests and quality checks done to estimate the contact lens power, you can be sure to get a clear view without your glasses. For more information visit Our Website
