Free Eye Care Tools & Calculators
Nine interactive tools built by our doctors: estimate where a child’s myopia is heading, check keratoconus risk, score dry eye symptoms, decode a prescription, convert glasses power to contact lens power, measure your PD. Each one explains what the number means and what to do next.
References, not prescriptions — your exam is where answers get personal
All nine tools
Each opens on its own page and runs in your browser — nothing is sent anywhere.
How to read the results
Each tool gives you a number or a category and explains what it usually means. It cannot replace an exam with our optometrists in Los Angeles: a risk score has not seen your cornea, and a symptom quiz has not measured your tear film.
What the tools are good for is arriving prepared. Bring the result to your visit, or mention it when you book online, and the exam starts from the right question. If a tool flags something urgent, such as a change on the Amsler grid, call 310-828-2010 the same day.

Reading is a start; an exam gives you an answer. Book online or call the office.
