Optical Department For those patients needing glasses or contact lenses, we offer a complete optical department. We carry a wide selection of high fashion eyewear and designer frames.
Comprehensive Vision and Eye Health Examinations Regular eye exams are an invaluable tool in maintaining healthy eyes by detecting and preventing disease. Some diseases develop slowly without causing pain or vision loss. Early detection of any problems can reduce the risk of further harm and allow for a choice of treatment options. The entire exam process can take an hour depending on the complexity of the problem. Each patient will be evaluated with a refraction, slit lamp, intraocular pressure and a retinal exam.
Pediatric Eye Care We take pride in maintaining the vision of our younger patients in an environment that is lighthearted and fun. We want to insure the good sight, vision, and eye health for the rest of your child's life and take a preventative approach to his/her general health and eye health. We will work with your child's primary care physician to help keep his/her eyes healthy. It is important that all of our pediatric patients have healthy and efficient visual systems to help make visual demands of learning in school easier and fun.
