Canada’s vision health professionals want Canadians to be mindful of the risks that come with wearing spooky or kooky cosmetic contact lenses for Halloween.
Optometrists, ophthalmologists, and opticians with the Canadian Ophthalmological Society (COS), the Canadian Association of Optometrists (CAO) and the Opticians Association of Canada (OAC) are recommending against the use of non-corrective cosmetic contact lenses, due to the serious and sometimes irreversible vision loss they can cause.
But the organizations also suggest prescriptions and proper instructions be followed closely, to help to minimize the public health risks posed by these medical devices.
“Decorative contact lenses can put people at risk for bacterial infections, allergic reactions, or significant damage to the eye’s capacity to function, with the potential for irreversible sight loss,” Dr. Barry Thienes, president of the Canadian Association of Optometrists said in a media release. “CAO recommends talking to your eye doctor first and obtaining a prescription before putting these medical devices on your eyes.”
Cosmetic contact lenses can pose a particular risk. Cosmetic contacts sold at Halloween often cover a larger portion of the eye.
These lenses do not correct vision, but change the colour and appearance of the eye for a dramatic effect.
They can be particularly problematic because they are more difficult to remove than other lenses. They do not have the same level of oxygen permeability as other lenses and all the risks associated with corneal oxygen deprivation are multiplied many times over.
Inflammation and ulceration can develop quickly and could result in permanent damage to the eye and to vision, CAO warns.
“As an eye physician and surgeon, I often have to treat the damage caused by non-corrective cosmetic contact lenses, including corneal ulcers which can lead to permanent vision loss,” said Dr. Guillermo Rocha, MD, FRCS(C), president of the Canadian Ophthalmological Society. “Contact lenses should not be thought of as fashion accessories or makeup – they are medical devices that require a prescription from an eye care professional. The eyes are one of the most delicate and important parts of the body, so what you put in and on them must be medically safe”.
Todd Smith, president of the Opticians Association of Canada notes, “It is no coincidence that all eye health care professionals are in agreement here. Contact lenses absolutely need to be fit by a licensed professional, the risks of injury are too great to ignore.”
Complications that may result in vision loss include:
• Scratches on the cornea from a poor fit
• Eye infection from improper use and handling
• Either of the above from inferior materials used to make the devices
CAO, COS and OAC commend the Federal Ministry of Health and Health Canada on their decision to advance regulations that will require the same medical device safety standards for non-corrective or ‘cosmetic’ contact lenses as prescription or corrective contact lenses, in accordance with Private Member’s Bill C-313, An Act to Amend the Food and Drugs Act (non-corrective contact lenses).
All three organizations have supported legislative change for many years pertaining to cosmetic contact lenses.
In July 2016, Health Canada announced that cosmetic contact lenses will be regulated as Class II medical devices, similar to corrective contact lenses. This means manufacturers of non-corrective contact lenses will have to apply for a medical device license to sell the products in Canada. As well, importers and distributors of the products will be required to obtain a medical device establishment license.
The coming into force of these regulations has been delayed until July 2017 in order to meet Canada’s obligations on technical barriers to trade, and to allow manufacturers of non-corrective contact lenses to bring their operations into compliance with the new requirements.
Due to the risk of harm posed by non-corrective contact lenses, Canada’s vision health professionals maintain that their use should require a prescription from an authorized professional.
