For all contact lens wearers and those who wish to wear contact lenses, contact lens examinations in addition to comprehensive eye exams are incredibly important. A prescription for eyeglasses is not the same as a contact lens prescription as glasses sit in front of the eye and contact lenses sit directly on the eye. This may alter the strength of prescription required. When deciding on the best contact lens option for you, your optometrist will go through an extensive selection process considering various factors including prescription, material, curvature, diameter, fit, coating, oxygen permeability, deposit resistance, moisture content, cleaning solution, and lifespan of the lens. They will assess your vision in the contact lenses to ensure they are providing you with the best vision possible, fitting and moving on your eyes correctly, comfortable to wear and not causing any ocular complications. Contact lenses are Health Canada approved and FDA regulated medical devices and as such, it is important that they are fit and regularly examined by a licensed eye care professional. Poor fit and improper use can damage the health of your eyes and potentially lead to blindness.
