When considering whether to buy your glasses online, at first it may seem more convenient and likely less costly. But the prescription given to you by your optometrist is only one piece of information that will determine how effective your glasses will be in improving your vision. Let’s consider the pros and cons:

Pros of buying online:

  • Wider selection of styles and colors
  • Many choices between different websites
  • Often can save on cost (but more on that later)

Cons of buying online:

  • You miss out on having a trained professional aid you in ensuring your glasses are the right fit in
    terms of comfort and effectiveness
  • Quality control of frames may often be sacrificed to maintain that low price you see online
  • Specific measurements such as PD, finding the best optical center, and measurements for
    progressives will either often be wrong or not available for online retailers
  • Prescription issues in general occur much more commonly when ordered online as opposed to
    in person

What could initially be seen as a way to save time and money in the first place may end up more costly for both in the long run if any of the above issues occur. In addition, common complaints with improperly selected glasses may include: headaches, fatigue, nausea/dizziness, eyestrain, glasses slipping off the nose, and pain/pressure marks on your nose/around the ears. Those with high prescriptions, children, complicated prescriptions, and multifocal prescriptions should especially consider in person options as opposed to online.

As a patient, understanding the role and the services offered by each of these three eye care
professionals will help you get the specific eye care you need, know what questions to ask, and work
with your health care provider to determine appropriate solutions that work for you.

Optometrists

Optometrists perform eye exams to check the overall health of your eyes and issue prescriptions for contact lenses or glasses, or low vision devices. The optometrist will perform a number of tests including visual acuity (how well you can see letters/symbols from a distance and near), your ability to see colour, your depth perception, retinal health, the pressure inside your eyes etc. The optometrist may use eye drops to dilate your pupils to help them detect conditions such as glaucoma, cataracts and macular degeneration and more.

Ophthalmologists

An ophthalmologist is a medical doctor who specializes in eye health and related diseases. Ophthalmologists undergo post-graduate training that qualifies them to treat eye diseases both medically and surgically. Ophthalmologists provide surgical solutions to common eye problems such as cataracts, and monitor eye conditions like glaucoma as well as perform laser corrective surgery.

Opticians

Opticians fit, adjust and dispense prescription and non-prescription eyewear. They do not perform eye exams nor prescribe but can assist with filling your prescription, adjusting glasses, and ordering new/replacement contact lenses.
