Your contact lens prescription is a set of specifications that allows you to buy contact lenses that will aid your visual needs. It will state the power of lens you need, the size, and the recommended brand. If you have a particular condition such as astigmatism; or require a more complex multifocal lens, your prescription may include other details.
A contact lens prescription will be issued to you after an eye exam by a qualified practitioner. They will establish both your visual requirements, and recommend replacement routines based on your lifestyle and the sensitivity of your eyes.
Do I need a prescription to order online?
Yes. We require that you have a valid, unexpired prescription for the contact lenses you ordered. – it is the only way to ensure you are ordering the right lenses for your eyes. After you submit your order, we will act on your behalf to quickly verify your prescription information with your eye care provider so we can get your subscription started. By ordering lenses from Cherie’s Optics, you’re giving us permission to contact your eye care provider on your behalf to verify your prescription.
How do I order if I don’t have a physical copy of my prescription?
It’s easy! After selecting the brand and type of contact lens you were prescribed, simply enter your power and other relevant parameters (e.g., base curve, axis, cylinder) for each eye. Next, select your eye care provider from our database (or type it in if you don’t see your provider listed). We’ll confirm the rest, and will reach out to your eye care provider on your behalf to ensure we have the right information.
How do I read my prescription?
Your contact lens prescription will likely have a few codes and abbreviations that might seem confusing at first. Here’s our easy guide to understanding your prescription.
• (BC) Base Curve – This is a measurement of the curvature of the contact lens. Always done in millimetres, this figure determines how well a contact lens will fit the eye.
• (DIA) Diameter – As you’ve probably guessed it’s the diameter of the contact lens also written in millimetres like the base curve, it tells the optician which width of lens best fits your eye.
• (PWR/SPH) Power/Sphere – This figure indicates whether you are long or short sighted, and how weak your vision is. Long-sightedness is indicated by a plus (+) and short-sightedness by a minus (-). The higher the figure, the greater the need for visual correction.Your sight is measured in diopters. So you may also see your power abbreviated to ‘D’.
• (CYL) Cylinder – This figure is only present on prescriptions for astigmatisms. It indicates the severity of the astigmatism, and will always be a minus (-) quality.
• (AX) Axis – An axis indicates the direction of the curve needed to correct an astigmatism. It will be a number between 0-180.
