About ODReference
Optometrist-built reference
Why ODReference exists
I am an optometrist and web developer who ran into the same problem many of us face in clinic: jumping between PDFs, textbooks, personal notes, and paywalled sites just to confirm a dose, vertex a prescription, or check a normal value. ODReference grew out of that frustration as a single, fast place to get reliable answers during real patient care.
ODReference brings together contact lens calculators, ophthalmic medication tables, and clinical reference values designed for chairside use. The goal is simple: help you move from decision to documentation with less friction, whether you are converting a refraction to a contact lens power, confirming glaucoma dosing, or reviewing dry eye testing norms.
Every page is designed to be clean, mobile friendly, and quick to scan in a busy clinic. Tables and articles emphasize the details that matter most in exam rooms and on call: dosing with brand and generic names, age and pregnancy guidance, replacement schedules, lens parameters, clinical decision frameworks, and practical pearls that differentiate from encyclopedic or patient-facing sources.
Content is reviewed and expanded over time to reflect evolving guidelines, new products, and changes that genuinely improve patient care.
Your feedback shapes what comes next. If a calculator is missing, a table is incomplete, or a topic needs a deeper dive, I would love to hear from you.
Thank you for the work you do and for spending part of your day here. I hope ODReference helps you save time, avoid errors, and deliver even better outcomes for your patients.
