I have been going to Dr. Jacobs for a few years. A previous doctor was unable to reach a stable prescription for my eyesight. After a day or two trying new contact lenses my vision would start to degrade. Dr. Jacobs had the experience and knowledge to determine that my vision was not degrading, rather my eyes reacting in a positive way to lenses that allowed more oxygen through. And between my age and the increased oxygen, my eyes were calling for less power. Highly recommend Dr. Jacobs.
