Purchasing glasses online is certainly convenient but it is not without risks when done
without professional fitting and dispensing. Ordering glasses online is very different
than your average online shopping experience. It is important to know that licensed
optical professionals are trained in the proper manufacturing, fitting, measuring, and
dispensing of eyewear. When making a glasses purchase online, the consumer is
essentially taking on the role of a trained optical dispenser. This role includes taking
critical measurements and making decisions with respect to lens and material selection.
There is an inherent risk associated with making these determinations without the
proper skills and training.
Potential consumers should be aware of a number of factors that go into converting an
eyeglass prescription into glasses that are both comfortable and provide clear vision.
• Taking an accurate measurement of the distance between the two eyes. This is called
the interpupillary distance (PD)
• Obtaining the proper measurement of the optical centers (OC) in order to avoid
eyestrain and pulling.
• Determining the height to place the optical center of the lens in your selected frames
• Measuring how high to place the bifocal (for those patients who need it)
• Determining the most appropriate lenses material and lens index given the patient’s
prescription, as well as work and lifestyle demands.
• Choosing the appropriate measurements for the lenses to best suit the patient’s
lifestyle or work environment.
• Taking the appropriate base curve determination to control magnification, especially
in cases where there is a difference between the curvatures of the two eyes.
• Proper selection of frame size, eye size, bridge width, temple length, shape, wrap,
material, and overall fit to ensure good comfort and vision with no distortion as
well as cosmetically acceptable lens thickness.
• Properly adjusting the frame to your face
Before the glasses are ready to be dispensed and used by the patient, a trained optical
dispenser should ensure that they have been properly manufactured and are within
acceptable tolerance. Then the appropriate adjustments should be made to ensure the
glasses fit the patient’s face correctly to ensure clear and comfortable vision. Poorly
manufactured or poorly fitted glasses can cause eye strain, headaches, pulling, and
One study published in 2011 showed that nearly half the glasses purchased online failed
to meet the recommended quality standards. These glasses did not meet either the
optical requirements for the patient’s visual needs or the physical requirements for the
patient’s safety. As stated by the College of Optometrists of Ontario, purchasing
prescription eyeglasses online is not regulated. In Ontario, selling prescription
eyeglasses by any unlicensed entity is illegal.
