Thomas A Aller OD

Optometrist in private practice, San Bruno, CA

Thomas Aller, OD, FBCLA graduated from the UC Berkeley School of Optometry in 1983 and has been in private practice in the San Francisco Bay Area since then.

For twenty five years he has been researching the use of bifocal contacts for the control of myopia. After receiving one of the world’s earliest patents for a method of myopia progression control, he began collaborating with Brien Holden, Earl Smith and the Vision CRC on their anti-myopia program. This R&D effort is geared toward producing contact lenses that provide excellent vision, while reducing peripheral hyperopic defocus in an attempt to reduce myopia progression.

In collaboration with Christine Wildsoet, he conducted the world’s first prospective randomized clinical trial on the use of bifocal contact lenses in children with near esophoria and showed about 80% reduction in myopia progression as compared to single vision contact lenses. They also published a case study on a pair of identical twins that demonstrated dramatically lower myopia progression in the twin wearing bifocal soft lenses compared to the twin wearing single vision contact lenses.

Dr. Aller is the principal investigator in a new prospective randomized clinical trial of the use of contact lenses with peripheral minus power to stimulate axial elongation in axial hyperopes.


Dr. Aller has several patents in the area of myopia control, licensed to or shared with the Vision Cooperative Research Centre. He is collaborating with the Brien Holden Vision Institute on their myopia control programs and receives travel grants.
