Appointments and Hours


It is best for both the patient and our office schedule that an appointment be arranged in advance. This not only saves you time, but allows us to answer your specific questions and explain all of your vision options.

A thorough eye examination requires approximately 30-40 minutes, excluding time for frame selection, or contact lens trial wear if necessary. We make every effort to honor each time commitment and request that the same courtesy be extended to us. Please notify the office if an appointment needs to be rescheduled or cancelled in 24 hours so other patients may be accommodated and to avoid any missed appointment fees.

Our office hours are:

Monday: 9:45am - 5:00pm

Tuesday: 10:00am - 7:00pm

Wednesday: 10:00am - 6:00pm

Thursday: 10:00am - 5:00pm

Friday: By appointment only

Saturday: By appointment only

Sunday: Closed


Eye and vision problems don’t always happen during normal business hours. If it is a life-threatening emergency, call 911. Should you require emergency vision service outside of our office hours, please call 510-218-2927.
