Get an Eyewear Prescription in Vancouver Today

If you have difficulty seeing, you will likely need a doctor to provide an eyewear prescription. Vancouver residents have long been coming to Granville Mall Optical for personalized eye care to improve your vision and your quality of life. Getting specialized eyeglasses following a comprehensive eye exam is a great way to improve your vision and keep your eyes healthy. While some people think that reading glasses from a drugstore will be enough to help their eyes, they lack the personalization that makes prescription eyewear such a perfect fit. So don’t take chances with your eye health and schedule an appointment with our doctor to get your eyewear prescription.

How to Read Your Eyewear Prescriptions
An eyewear prescription in Vancouver is different from the kind of prescription you might get from your physician. They often have names and terms that do not make sense to anyone except the optometrist and other eye specialists. Here are some terms you may find on your eyewear prescription and what each one means:

  • OD and OS: These are abbreviations for oculus dexter and oculus sinister, which are Latin for right eye and left eye, respectively. Some optometrists have switched to the more obvious R and L.
  • Sphere: Sphere refers to the amount of lens power necessary to correct nearsightedness or farsightedness. Because the correction needed here is equal along all axes, it is referred to as sphere. Numbers with a plus sign (+) indicate farsightedness, while numbers with a negative sign (-) indicate nearsightedness.
  • Cylinder: This refers to the amount of lens power for astigmatism. If this space is zero or blank, you either don’t have astigmatism or it is not severe enough to affect your vision. It is called cylinder because it measures just the front of the eye, which is not spherical.
  • Axis: If there is something written under cylinder, there will also be something written for axis, which represents where on the eye your vision is blurred due to astigmatism.
  • Add: Short for “additional,” this refers to any necessary magnifying power to be applied to the bottom part of the lens. This only applies to individuals who need bifocal or progressive lenses.
  • Prism: This refers to the amount of correction needed, measured in prism diopters (p.d.), to compensate for eye alignment issues. This area isn’t frequently used, and only a small percentage of eyeglass prescriptions include prism.

If you are unsure what your prescription means, ask one of our optometrists. We are happy to answer any questions you might have.

Glasses Prescriptions vs. Contact Lenses Prescriptions
While there are some similarities, a prescription for contact lenses is not the same thing as an eyewear prescription. In Vancouver, and throughout most of North America, eyewear prescriptions are only good for eyewear, and contact lens prescriptions are only good for contact lenses. Because contact lens prescriptions factor in things like base curve, lens diameter, manufacturer and brand name of the lens, an eyewear prescription cannot be used for contact lenses. Another difference between eyewear and contact lens prescriptions comes from the fact that glasses rest about 12 millimeters in front of the eye, whereas contact lenses are directly on the cornea.

How Long is an Eyewear Prescription in Vancouver Good For?
Most eyewear prescriptions are good for up to 1 year after they are written. However, they can be good for up to 2 years in some instances. To continue maintaining your visual health, it is important to have regular check-ups with your optometrist. It’s recommended that individuals under 40 with no history of eye problems get a routine vision check every 2 years. Individuals over 40 should have their eyes thoroughly checked every 2 to 4 years. And those with a history of vision problems should get checked once a year.

Even though things like reading glasses may seem like a quick fix to minor blurriness, that’s really all they are: a quick fix. They won’t correct your vision the way your eyes need them to, and they won’t be durable tools to wear day-in and day-out. For that, you need glasses that are properly constructed with the expertise of a skilled optometrist. With the help of our eye doctor, we can have you seeing clearly in no time at all.
