Buying glasses online vs in-clinic: what you need to know

Online shopping has become increasingly popular in recent years—even for prescription glasses. However, in Quebec, few local businesses offer the option to buy prescription eyewear online. Why? Simply because online sales don’t allow eye care professionals to deliver the same level of quality as what you’d receive in an optometry clinic.

The 4 Essential Steps to Buying Glasses 

1. CHOOSING THE RIGHT FRAME

In a clinic, you can try on hundreds of styles. Online browsing is great for inspiration, but just like with shoes or clothing, nothing beats trying frames in person. You’ll see the true color, find the right fit, and feel the comfort before making a decision. 
 

2. SELECTING THE RIGHT LENSES

Once you’ve chosen your frame, it’s time to pick your lenses. There are many options, and making the right choice without guidance can be tricky.

Do you need lens thinning? What kind of coatings should you consider? In-clinic, our professionals help you choose the best lenses based on your prescription, lifestyle, and visual needs—whether you spend hours on screens, drive frequently, or spend time outdoors. 

3. LENS POSITIONING

Proper lens centration is crucial for clear, comfortable vision.

This step involves aligning the optical center of the lenses with your pupils, based on precise measurements taken during your visit. Poor centration can lead to eye strain, headaches, and blurred vision—issues that can’t be corrected remotely. 
 

4. FRAME ADJUSTMENT

Using specialized tools and techniques, opticians adjust your glasses to fit your face perfectly. A well-fitted frame prevents slipping, pressure behind the ears, and discomfort over time. This personalized adjustment is key to long-term comfort and eye health. 
 

 The Limits of Buying Glasses Online

Online shopping is great for exploring styles and options, but it comes with risks:

• Uncertainty about fit, color, and comfort
• Difficult or impossible returns and adjustments
• Lack of personalized advice on lenses, coatings, and materials

Online shopping is especially not recommended if:

• You need progressive lenses
• You have high or evolving myopia
• You need glasses for screen use or specific work environments

These types of glasses require precise measurements that simply can’t be done remotely with the same level of accuracy as in a clinic. 
 

Why In-Clinic Service Makes a Difference

At an optometry clinic, you’re supported by trained professionals who take precise measurements and offer expert advice tailored to your needs.

You also benefit from product warranties and high-quality after-sales service—something online retailers often can’t match.
