Services
Eye Examination
Our comprehensive eye exams assess both vision correction and ocular health, utilizing advanced diagnostics to detect conditions like glaucoma and macular degeneration. We provide personalized prescriptions for glasses or contact lenses, ensuring accuracy through our Accurate Prescription Guarantee. Each exam includes a detailed review of medical history and tailored recommendations for ongoing eye care.
Urgent/Emergency Eye Services
We offer prompt treatment for eye injuries, infections, and sudden vision changes, including scratched corneas, foreign object removal, and acute glaucoma symptoms. Our state-of-the-art equipment enables immediate digital imaging of the eye's interior, ensuring rapid diagnosis and intervention. Emergency appointments are prioritized to prevent complications and preserve vision during critical situations.
Pediatrics
Specialized pediatric exams identify vision issues in infants, toddlers, and school-aged children, addressing conditions like amblyopia and strabismus. Our non-invasive techniques accommodate non-verbal patients, using advanced instruments to detect developmental problems early. We provide follow-up care for vision-related learning challenges and ensure proper visual development through customized treatment plans.
Glaucoma Testing
Our glaucoma diagnostics include tonometry, visual field testing, and optic nerve imaging to detect pressure-related damage before symptoms arise. We employ pachymetry for corneal thickness analysis and gonioscopy to evaluate fluid drainage angles. Early intervention strategies, such as medicated drops or laser therapy, are implemented to prevent vision loss while monitoring progression through regular follow-ups.
Retinal Digital Imaging
Digital retinal imaging captures high-resolution images of the eye's posterior structures, enabling early detection of macular degeneration, diabetic retinopathy, and retinal tears. This non-invasive procedure creates a permanent health record for tracking changes over time. The technology also aids in identifying systemic conditions like hypertension and cardiovascular disease through ocular manifestations.

I had booked an appointment at least a month ago with my optometrist, whom I have been dealing with for 40+ years to have him complete the Vision Waiver Certificate form. On the day of the appointment, I was told that the form cannot be completed since his machine was broken and did not know when it would be repaired. He did not provide me with any alternate solution. A family member recommended me to give Dr. Alex Mah a call.
Dr. Mah and his staff (Carol and Christina) were able to book me the last appointment on the following day (Saturday)and got the form completed. Dr. Mah and his staff

My spouse and I have been patients of Dr. Mah's for many years.
Dr. Mah is welcoming, professional, and provides excellent, efficient services. His team, including Christina, are so friendly, helpful, and have excellent taste in making one's appearance shine with eye wear recommendations! While COVID has created chaos and uncertainty throughout our society, I feel that Dr. Mah's staff have gone above and beyond to adapt to and meet the needs of its patients, especially during my family's recent eye exams and purchase of new lenses. We have always received exemplary care, and we will remain loyal

I am a long time customer of Dr. Alex Mah and I felt compelled to write a review due to the exceptional service I receive. I have dealt over the last 6 years with both Christina and Dr Alex Mah. From the time you walk in the door and greeted always by a warm welcome you feel like you are in "great hands". Between the process of eye examinations or the selection of glasses their service is impeccable with patience to ensure your needs are exceeded. I would highly recommend this business for all your optical needs. Thank you and keep up the great service
