Serving the Bay Area communities of Hayward, San Leandro, San Lorenzo, Pleasanton and others for more than 60 years!

Eyes are important indicators of overall health, and comprehensive eye care goes beyond a prescription for glasses or contact lenses. At Primary Eyecare Optometrics, we take the time to get to know you, your eye care history, and your vision needs. Our optometrist provides the expert care, advice, options, and follow up you need whether you are a new patient or an existing one. Schedule an appointment today!

Use of Specialty Contact Lenses:

Our doctors diagnose and treat Keratoconus which is a pathological steepening of the cornea. This condition is controlled with the use of special contact lenses. One of these lenses is a “skirted” lens which combines rigid and soft materials. The rigid center slows the progression of the disease and the soft skirt maximizes comfort.

Dr. Osias is certified to fit “Corneal Refractive Therapy” contact lenses. These lenses change the shape of your cornea while you sleep and thereby correct myopia. Our doctors in Castro Valley, CA also use “bandage” contact lenses to assist healing and provide relief from corneal abrasions or other corneal trauma.
