Buying contact lenses online comes with risks to your vision and eye health. We’re here to help.
Why is it important to take extra care when buying contact lenses?
It is important to remember that every contact lens product is unique and designed for a particular purpose. This includes everything from material, curvature, fit, oxygen permeability, deposit resistance, moisture content and lifespan.
What risks are associated with buying online?
Remember that contact lenses are medical devices that sit directly on your eyes and can cause problems if improperly fit or not monitored. Just because you have a prescription (new or old) does not mean you will get the appropriate product for your unique eyes, unless you make your purchase from an eyecare professional.
There are a number of risks associated with online ordering:
- Some sites do not verify the prescription. Without proper verification, you risk wearing an incorrect or improperly fitting lens.
- Many online sites (including those based in Canada) sell products that have not been approved by Health Canada. The safety of these lenses has not been tested.
- Lenses from overseas may be exposed to large temperature changes in uncontrolled warehouses or transportation vessels. This can affect the integrity of the lenses that can lead to eye health issues.
- Overseas distribution channels may have grey market (counterfeit) product. There are no controls to ensure that Internet sites only source lenses directly from the manufacturer.
- You may not be able to get replacements or exchanges with an online vendor.
How can I make sure my contact lenses are working for me?
See your doctor of optometry ever year to monitor the health of your eyes and get personal advice on your contact lens needs. This includes seeking immediate care if you experience any discomfort or vision change, and reporting any problems that may arise.
By working with your doctor of optometry, you can ensure:
- The proper contact lens prescription, curvature, and modality based on lifestyle needs, and measurements of your eye curvature, tear chemistry, and prescription.
- The appropriate selection of care system and solutions based on compatibility with different lens materials and compatibility with your eyes.
- Professional monitoring to ensure optimum eye health, good vision, and comfortable wear.
- Updates with new lens technology that may better suit your vision needs or lifestyle demands.
