Why does my eye doctor do that puff of air test? Many people wonder, and some may know that it is performed to check your eye pressure which helps screen for signs of Glaucoma. January is Glaucoma Awareness Month and we want you to know how important it is to screen for eye diseases like Glaucoma with each vision wellness exam. Both Dr. Bui and Dr. Lee are Optometric Glaucoma Specialists. You can find out more information about what Glaucoma testing and treatment services we offer at here at Lighthouse Eye Care right on our website Glaucoma Testing and What Is Glaucoma.
