Our Eye Doctors Answer Your Eyecare Questions

Q: Are Online Coloured Contact Lenses Safe for My Eyes?

A: Recently the optometrists at Foresight Eyecare have noticed a surge in inappropriate contact lens fits from online purchases. New contact lens websites that have recently come up present “new” contact lenses seem like new technology. When the doctors assessed these “new” lenses, they are in fact lenses that were popular from 1980’s and 1990’s technology e.g. methafilcon A, polymacon. This contact lens generation has insufficient oxygen permeability for more than 10 hours of wear time, and even lower wear time for higher prescriptions.

The contact lens edge design is also crucial for eye health, as a lens that fits tightly or decentres and makes contact with inappropriate parts of the eye can cause damage to the cornea or other parts of the eye. The lens fit is crucial for clear vision, and to avoid discomfort and micro-abrasions to the eye that can lead to eye infection or inflammation, and in extreme cases, certain infections can lead to ulcers and blindness. In July 2016, the Government of Canada started to regulate decorative contact lenses (also known as cosmetic or coloured contact lenses). They are considered Class 2 medical devices, and in order to sell these contact lenses, distributors need to provide assurance that the contact lens imported into Canada have procedures in place to protect the public should a problem with a medical device be identified.

When you receive a contact lens fitting through an optometrist or licensed contact lens fitter, the contact lens is selected based on measurements of your eyes, and discussing how you would wear the lenses before making recommendations on best lens design, material, and modality for you. Then when you receive your contact lenses, follow-up is done to ensure that they have been properly manufactured and fit properly.

What Our Patients Say

I was extremely impressed with Dr Leong when I showed up at her office without an appointment in early May. I had noticed something odd with my 1-month old’s son eye while I had been up with him the night before. There was a white reflection in his left eye. I of course had gone on the Internet and looked this up and had convinced myself that my son had retinablastoma (a type of cancer).

Dr. Leong’s receptionist was very gracious when this sleep deprived crazed mom showed up without an appointment. She let me know that Dr. Leong was not in yet. She often came in early and would be there shortly. Dr. Leong saw me immediately when she arrived. She was calm and reassuring when she examined my son, taking my concerns seriously. She quickly assessed that she suspected that my son had a cataract in his eye. She then tried to get him in to see an ophthalmologist that day.

Unfortunately, the pediatric ophthalmologist was unable to see him. Dr. Leong then spent the day on the phone between her appointments trying to get him into the vision clinic at Alberta Children’s Hospital. They were also unable to see me so Dr. Leong made me an appt with the ophthalmologist on call at the Rocky View Hospital the next day, which was of course the Saturday of the may long weekend. Her diagnosis was confirmed. I am happy to report that we have since seen the pediatric ophthalmologist at Alberta Children’s Hospital and Drew’s surgery dare is scheduled.

Thank you Dr. Leong for working so hard to help Drew. Your commitment to getting Drew seen was admirable. We are unable to express how much your diligence and persistence has benefited Drew, our family and his sight. Thank You. – Michelle
