At 4S Eyecare we pride ourselves on being your comprehensive, "one stop shopping", eyecare provider.
Our services include:
We include digital retinal imaging and corneal topography in our comprehensive exam. Most offices charge an extra fee for these additional tests, but our doctors feel so strongly about giving ALL patients the best patient care, that these tests are automatically included in your comprehensive examination with no extra fees.
Digital Retinal Imaging
We use a digital camera to document the optic nerve head, macula, retinal blood vessels and retina. This digital image provides us with a baseline point to monitor and detect eye disease such as high blood pressure, diabetes, glaucoma and macular degeneration. This allows us to asses any changes in your retina at each visit.
Corneal Topography
Our corneal topographer is a state of the art imaging device that maps out every point of the cornea (the front surface of the eye). Corneal topography is important to obtain the best contact lens fit and to detect any corneal eye disease such as keratoconus. Additionally, topography is useful to determine a patient's candidacy for Lasik and other laser vision corrections.
Optometric Vision Therapy is the branch of optometry that is specifically devoted to optimizing an individual’'s visual performance.
Its procedures are designed to:
As a Optometrist who practices Vision Therapy, Dr. Harpur designs individualized, supervised programs for utilizing lenses, prisms, light, and specific vision therapy techniques to enhance a patient's visual skills, helping the brain to more efficiently process visual information.
Who can be helped by Vision Therapy?
Anyone, child or adult who experiences vision related difficulties like the following:
Learning-related vision problems.
Difficulty sustaining clear, comfortable vision results from poorly developed or inefficient visual skills. Lack of efficient visual skills interferes with a person's ability to acquire or process visual information and results in Learning-Related Vision Problems. Vision Therapy develops the necessary visual skills for effective reading, writing, and learning. These visual skills include:
As these skills are enhanced through vision therapy, they are reinforced and become second nature through repetition and integration with other motor, sensory and cognitive systems. Experiments have shown that enhancing visual skills with vision therapy makes reading more efficient, learning easier, and may increase a patient's ability to visualize, conceptualize and create.

What is Seeing Double or Double Vision?
Near Point Stress-Related Visual Discomfort and Related Problems:
Our fast paced, 21st Century modern world places intense demands on our visual systems. Prior to the 20th Century most people were illiterate and used their eyes far less frequently for near vision tasks. That has changed dramatically. The human visual system, ideal for hunting, fishing, and farming is now called upon for constant near work for reading and computers, whether at school, office or home. Children in particular, but many adults as well, experience a wide variety of visual and general body symptoms related to the environmental impact of excessive close work. These may include blurred vision, skipping letters and words, double vision, eyestrain or fatigue, avoiding near work, or even headaches, nausea and vertigo.

Optometric Phototherapy
( Syntonic Optometry )
This is the application of seleceted wavelengthe (colors) of light through the eyes to expand constricted visual fields.
Children under academic or other stress and adulta who have experienced head or whiplash type injuries often suffer from visual disturbances that can interfere with school or work performance. Patients having these types of visual disturbances will often have severely constricted visual fields (tunnel vision). We can treat these visual fields using colored light therapy and as the fields return to normal, we see a significant reduction in our patients' sypmptoms. Phototherapy is used in conjunction with standard vision therapy techniques as needed.
