Why do I need prescription glasses when I can get reading glasses at any drugstore?
The inexpensive glasses you buy off the rack don’t cost much for a reason: they are standard lenses in a cheaper frame. These lenses may just give you a headache if they are not quite right for you. You may need a special prescription for each eye, and you want to make sure your eyes center correctly behind your lenses.
How do I know my new glasses are just right for me?

Have a professional thoroughly examine your prescription glasses to ensure they fit your vision needs. A regular eye exam will check not only changes in your vision but also the overall health of your eyes.

Purchasing glasses
Ordering eyeglasses online may seem easy, but it is very different than ordering your average consumer item. It is important to know that opticians are university trained in the proper manufacturing, fitting, measurement, and dispensing of eyewear.
When ordering online, the untrained consumer is, in essence, taking on the role of a trained optical dispenser. This includes taking critical measurements and making critical decisions with respect to frame, lens and material selection. There is an inherent risk associated with making these determinations without the proper skills and education.
All consumers should be made aware that there are a number of factors that go into converting an eyeglass prescription into a quality optical device that provides clear, comfortable vision. These include:
-
Proper measurement of your interpupillary distance (PD) at both distance and near focal points.
-
Accurate measurement of the optical centres (OC) in order to avoid eyestrain and pulling.
-
Determination of the most appropriate type and index of lenses given your prescription as well as work and lifestyle demands.
-
Proper education and selection of tints and coatings for your lenses to best suit your lifestyle or work environment.
-
Appropriate base curve determination.
-
Proper selection of frame size, eye size, bridge width, temple length, shape, wrap, material, and overall fit to ensure good comfort and vision with minimal distortion and cosmetically acceptable lens thickness.
When you receive your glasses, a trained optical dispenser should ensure that they have been properly manufactured, are within acceptable tolerance, and fit your face correctly to ensure ideal vision. Poorly manufactured or poorly fitted glasses can cause eye strain, headaches, pulling, and blurred vision.
A September 2011 study found that 44.8% of eyewear ordered online FAILED at least one parameter of optical or impact testing. In addition, 28.6% were out of optical tolerance.
How do I know if my child needs glasses?
Regular eye exams are recommended yearly for children. Your child’s first eye exam should be done between the ages of 6 months to 1 year. More frequent exams could be necessary if you notice:
-
Sits too close to the TV
-
Holds a book very close or avoids reading
-
Squints or tilts head to see better
-
Rubs his or her eyes often
-
Has light sensitivity or watery eyes
-
Closes one eye to read or watch TV
-
Avoids activities that require seeing details
-
Has headaches or tired eyes
The government of Alberta covers yearly exams for children under their Alberta Health Care until the age of 19.
