Pia Tan, PVT, COEP-T, is Eyedeology’s Certified Optometric Vision Therapist. With over a decade of dedicated experience in vision therapy, Pia brings a combination of clinical expertise, compassionate care, and advanced training to every patient she works with.

Pia holds a Bachelor of Science in Nursing and is an accredited vision therapist through the Canadian Optometrists in Vision Therapy (PVT) Program. She is also a Certified Optometric Extension Program Therapist (COEP-T), holds the Post-graduate Vision Therapy and Applied Prism (PVTAP) Certificate, and is an active member of Vision Therapy Canada, the Optometric Extension Program Foundation (OEPF), and the College of Syntonic Optometry (CSO).

Pia works in close collaboration with Dr. Farrah Sunderji and Dr. Jessica Yang to design and deliver customized, personalized vision therapy programs tailored to each patient’s unique needs and goals.

Outside the clinic, Pia can often be found enjoying time with family, camping, hiking, or trying new recipes.
Pia is currently welcoming new patients and referrals and is committed to helping individuals of all ages build stronger visual skills, confidence, and quality of life through individualized vision therapy.

Areas of Special Interest

Binocular Vision, Eye Teaming & Learning

Pia has a special interest in assessing and treating binocular vision dysfunction, where the eyes struggle to work together, including convergence insufficiency, convergence excess, accommodative disorders, and oculomotor dysfunction. Because these visual skills are essential for reading and learning, Pia also works with children and adults experiencing learning-related vision difficulties, helping strengthen visual processing, eye coordination, and visual comfort for improved performance at school, work, and in everyday life.

Strabismus & Amblyopia

With extensive experience in vision therapy, Pia treats patients of all ages with strabismus (eye turns) and amblyopia (lazy eye) across all age groups. Vision therapy under Pia’s guidance provides a non-surgical, evidence-based approach to improving eye alignment, binocular function, and visual acuity, complementing any optical or medical treatment the patient may be receiving.

Concussion & Neuro-Optometric Rehabilitation

Pia provides vision rehabilitation for patients recovering from concussion and traumatic brain injury (TBI). Working alongside Dr. Farrah, Dr. Jessica, and multidisciplinary healthcare teams, she develops individualized rehabilitation programs to improve reading, balance, light sensitivity, and daily function, helping patients return to school, work, sport, and everyday life.

Primitive Reflex Integration, Therapeutic Prisms & Sports Vision

Drawing on advanced training in vision therapy, Pia incorporates a variety of techniques that support visual, neurological, and motor function. Her approach includes primitive reflex integration to address retained infant reflexes that can affect visual development and coordination, therapeutic yoked prisms to improve balance, posture, spatial awareness, and visual function, and syntonic phototherapy, a light-based therapy that supports visual processing and neurological function. As a member of the College of Syntonic Optometry (CSO), she works closely with our optometrists to incorporate syntonics into individualized vision therapy programs. Pia also provides sports vision training to help athletes enhance visual performance, reaction time, hand-eye coordination, and decision-making.

Advanced Myopia Control for Children

Recent randomized controlled clinical trial results presented at the ARVO 2026 Annual Meeting showed promising results for children aged 4–12. Among the 196 children who completed the study, those wearing MiYOSMART iQ showed no average myopia progression after 12 months. The study also found that excessive axial eye growth was reduced to levels below or comparable to those seen in children without refractive errors.

Designed to Help Control Myopia Progression

Myopia, commonly known as short-sightedness, can progress during childhood as the eye grows excessively. Managing myopia earlier in life may help reduce the impact of continued progression and the associated risks of high myopia later in life.

MiYOSMART iQ builds on the established D.I.M.S. Technology used in MiYOSMART lenses and introduces a Triple Enhanced Design (TED). This design incorporates three key enhancements:

  1. Defocus Segments Closer to the Center: The segments are positioned closer to the geometric center of the lens to provide continued exposure to myopic defocus across the near-peripheral retina.
  2. Higher Defocus Power: The lens provides a stronger myopic defocus signal intended to support myopia control.
  3. Extended Treatment Zone: A larger treatment area provides broader coverage of the child’s peripheral visual field, including when larger frames are used.

Clinical Results Across Different Age Groups

The clinical trial included children between 4 and 12 years of age, with results demonstrating myopia-control efficacy across the age groups studied.

For children aged 4–6 years, MiYOSMART iQ demonstrated 65% efficacy in spherical equivalent refractive error (SER) and 44% efficacy in axial length over 12 months. For children aged 7–12 years, the lens demonstrated over 100% efficacy in SER and 94% efficacy in axial length during the same period.

The study also reported a high level of compliance with daily, all-day wear among children across the age groups studied.

Built on Established D.I.M.S. Technology

MiYOSMART iQ represents an evolution of MiYOSMART, a myopia-control lens technology backed by more than 100 peer-reviewed scientific publications. The updated lens design builds on research into how the eye responds to myopic defocus and focuses on delivering a stronger and more consistently positioned defocus signal.

Since its launch in 2018, more than 15 million MiYOSMART spectacle lenses have been purchased by parents across more than 50 countries worldwide.

Supporting Earlier Myopia Management

The clinical findings for MiYOSMART iQ include children as young as four years old, representing an important development in spectacle-lens-based myopia control. Early-onset myopia can progress during a critical period of childhood eye development, making appropriate management an important consideration for children with progressive myopia. MiYOSMART iQ provides an advanced spectacle-lens option for children who require myopia management. An eye care professional can assess your child’s vision and determine whether this type of lens is appropriate for their individual needs.
