Eyewear for the
Way You See Life

Single vision lenses have one prescription power across the entire lens, correcting vision at one distance — near or far. Progressive lenses provide a smooth transition between multiple prescription powers in one lens, letting you see clearly at distance, arm's length, and up close without visible lines. Progressives require precise fitting measurements to perform well, which is why we take individualized measurements for every pair we dispense at Primaris Vision.

High-index lenses are made from materials that bend light more efficiently, allowing the lens to be noticeably thinner and lighter than standard plastic. They are most beneficial for moderate to strong prescriptions, where standard lenses can look thick at the edges and feel heavy on the face. Our opticians will recommend the right lens material based on your prescription strength and the frame you choose.

Anti-reflective (AR) coating reduces glare from headlights, screens, and overhead lighting, and makes your lenses appear nearly invisible so people see your eyes rather than reflections. Most patients benefit from AR coating, particularly for night driving and computer work. Modern premium coatings also add scratch resistance and easier cleaning. We will recommend a coating based on your lifestyle and how you use your glasses.

Office lenses (also called occupational or workspace lenses) are designed specifically for desk and computer work, providing wider, more comfortable viewing areas for your screen and workspace than general-purpose progressive lenses. They can help reduce visual fatigue and improve posture by allowing you to view your screen more naturally. If you spend much of your day at a computer, we can help determine whether a dedicated pair of office lenses would suit your prescription and working distances.

Blue light filtering lenses are a popular option, but current evidence does not show that blue light from digital screens is a major cause of digital eye strain. Symptoms such as tired, dry, or uncomfortable eyes are more commonly related to prolonged focusing, reduced blinking, screen distance, and uncorrected vision. During your eye exam, Dr. Yu can assess your symptoms and recommend appropriate options, which may include an updated prescription, anti-fatigue or computer lenses, or changes to your screen habits.

Your pupillary distance is the measurement between the centres of your pupils, and it determines where the optical centre of each lens is positioned. If the optical centres don't align with your eyes, lenses can cause eye strain, blur, or distortion — particularly with stronger prescriptions and progressive designs. At Primaris Vision, we take precise fitting measurements for every pair of glasses, including PD, fitting heights, and frame fit, so your lenses perform the way they were designed to.

In many cases, yes. We first inspect your frame to make sure it is in good enough condition to safely hold new lenses, since older frames can become brittle and may crack during lens insertion. If your frame is suitable, we will cut and fit your new prescription lenses to it. If there is a risk of damage, we will let you know before proceeding.

A short adjustment period is normal with a new prescription or new lens design, especially with progressive lenses. Your eyes and brain typically adapt within a few days to two weeks. If things still don't feel right after that, come back and see us — we verify every pair we dispense and provide follow-up adjustments to make sure your glasses fit and perform properly.

We offer children’s lenses in impact-resistant materials designed for safety and durability, along with frames sized appropriately for growing faces. For children with progressing myopia (nearsightedness), we also offer specialized myopia management spectacle lenses designed to provide clear vision while helping to slow myopia progression. Learn more on our Children’s Eye Exams and Myopia Management pages, or ask us about the options available for your child.

Yes. You’re welcome to visit our optical with a current prescription, even if your eye exam was completed elsewhere. We can help you select frames and lenses suited to your prescription, visual needs, lifestyle, and personal style.
