Who We Are

An Overview of Our Practice

Our optometric therapy practice is dedicated to the identification and successful treatment of a very special population of children. Children can develop numerous adaptations to cope with the discomfort of binocular vision dysfunction. These are adaptations that can affect a child’s ability to perform in reading and school.

A very large practice with over 3500 feet of office space

This is a very large practice with over 3500 feet of office space, directed toward treatment approaches of:

  • Vision training
  • Developmental optometry
  • Neuro-optometry

We have two doctors working full-time in these areas. The doctors and the two long-term staff members have a combined experience of 55 years in this field and have personally done well in excess of 100,000 sessions of therapy in the past 34 years.

This is a regional practice, with patients coming on a regular basis from Monterey, San Benito, San Benito, Santa Clara, and San Mateo Counties.

Treating Vision Dysfunctions

Binocular vision is vision in which both eyes are used together. Using two eyes accurately together has several important advantages, including:

  • Wider field of view
  • Fused information in the brain which results in precise depth perception.
  • Improved visual comfort

"Binocular vision dysfunction" is a term to describe a number of conditions in which the two eyes are not working together efficiently. Binocular vision dysfunctions can have many different causes and affect a person at many different levels, causing discomfort such as double vision, eyestrain, or headaches. It can result also in the development of conditions such as crossed eye and lazy eye.

"Visual information processing" is the ability of a person to input, understand, and act upon information received from the two eyes. It is a visual function that takes place in the brain, as opposed to a visual function that takes place in an eyeball.

"Vision information processing dysfunction" is a term used to describe a number of conditions in which the person is not able to input, understand, and act upon information received from the two eyes. Visual information processing dysfunction problems often develop as a result of a child’s efforts to cope with the discomfort of binocular vision dysfunction. Problems in these areas can have a huge impact on a person’s ability to function in a wide range of activities.
