Adult Eye Exams
Our comprehensive adult eye exams include vision analysis, eye health evaluation, and diagnostic testing. We use advanced tools like OCT-Angiography to detect conditions such as glaucoma, cataracts, and diabetic retinopathy. Our optometrists provide personalized recommendations for corrective lenses and treatment plans, ensuring optimal vision health for patients aged 19 and older.
Contact Lenses
We specialize in contact lens fittings, including custom options like OrthoTool for myopia control and scleral lenses for irregular corneas. Our team ensures precise measurements and comfort, offering daily, bi-weekly, and monthly disposables, as well as specialty lenses for astigmatism and presbyopia. Patients receive training on proper insertion, removal, and care.
Myopia Control
Our myopia control clinic targets children and teens to slow nearsightedness progression using OrthoTool-designed orthokeratology lenses. This non-invasive approach reshapes the cornea overnight, providing clear daytime vision. We also offer atropine therapy and lifestyle guidance to reduce eye strain from digital device use, ensuring long-term visual health.
Dry Eye Clinic
Our dry eye specialists diagnose and treat chronic dryness caused by meibomian gland dysfunction, contact lens use, or systemic conditions. Treatments include prescription drops, punctal plugs, and lifestyle adjustments. We utilize advanced diagnostics to identify root causes and tailor therapies like scleral lenses, which provide moisture and comfort for severe cases.
Vision Therapy
Designed for children and adults with binocular vision disorders, our vision therapy programs address amblyopia, strabismus, and eye teaming issues. Through customized exercises and tools like prism lenses, we improve focus, depth perception, and visual processing. Sessions are supervised by trained optometrists, ensuring measurable progress in comfort and functionality.
