Your Vision Source Olmos Park eye doctor.

Dr.Jason Deviney, O.D.

Dr. Deviney is a South Texas native, growing up in the towns of Alice and Freer. He received his Bachelors degree in Business Administration from Texas Tech University in 1994 but decided he wanted to help people see better.  So he re-enrolled and took the prerequisite courses needed and graduated from the University of Houston College of Optometry in 2000. Upon graduation, he practiced in Kingwood, Texas working his way to Clinical Director of the Kingwood Vision Source Laser Center. After nine years there, his family moved to Keene, New Hampshire to join a practice but missed Texas too much and is now back closer to home.

Dr. Deviney’s specialties include contact lenses, refractive surgery co-management, glaucoma management, ocular disease treatment, and treatment of binocular vision abnormalities that may cause reading comprehension problems in patients of all ages.

Dr. Deviney practices what’s known as Behavioral Optometry, which takes a holistic approach to vision care.  You are treated as a whole person and your visual problem as a part of the whole system.   Dr. Deviney has studied the effects of stress on vision. Through the use of carefully selected stress-relieving and preventive lenses and visual training, you can enjoy relief from even the most stressful close-up visual conditions.

At the beginning of 2016, Dr. Deviney took over the vision therapy practice of Dr. Mervyn Bloom here in San Antonio to help children with vision-related learning problems.  The practice is known as Vision Therapy of San Antonio.  The vision therapy practice has been expanded to help patients of all ages with amblyopia and strabismus as well as patients who have suffered from brain injury.

He is currently a member of the College of Optometrists in Vision Development, the Optometric Extension Foundation, the Ocular Nutrition Society, the Texas Optometric Association and the American Optometric Association.  He has also been on advisory panels for Allergan pharmaceuticals and contributed to articles in Optometry Times.

After purchasing this practice in 2015, he is now seeing patients full time in Olmos Park. Be sure to follow his Twitter account at

Dr. D has been married to his wife Christine since 1995 and their daughter Jillian will graduate from Alamo Heights High School in 2021!
