Dr. Liang designs customized vision therapy programs that improve focus, eye teaming, and visual skills, helping patients succeed at school, work, and sports.


Vision therapy is more than eye exercises, it’s a personalized program that retrains how the eyes and brain work together. Unlike glasses, which correct clarity, vision therapy treats how the eyes function.
Conditions we help with include eye tracking problems, convergence insufficiency, lazy eye (amblyopia), strabismus (eye turn), visual stress from screens, and attention issues often mistaken for ADHD.
By strengthening the way the eyes and brain coordinate, vision therapy can transform daily activities like reading, sports, and classroom learning.
Parents often notice their child struggling with reading, skipping lines, losing their place, or avoiding schoolwork. These challenges are not always about motivation; they can be signs of an undiagnosed visual issue.
We evaluate how a child’s eyes move, focus, and team together, then create a therapy plan tailored to their needs. Over time, children develop stronger visual skills, which improve confidence, academic performance, and comfort.
Parents appreciate the progress achieved by their children as we explain it step by step, in clear language and in their preferred language, English, Cantonese, or Mandarin.


Adults who experience headaches, migraines, or dizziness can benefit. Their focus on screens can be improved. Their driving and balance can be improved with better visual-spatial skills.
We help patients with double vision, digital eye strain, and post-concussion visual difficulties. Some adults experience headaches or difficulty concentrating on screens; others find their vision hasn’t felt the same since an accident or illness.
