Vision Therapy

Dr. Shifreen is not an optometrist or an opthamologist. Dr. Shifreen does not diagnose or treat any specific eye diseases such as glaucoma or cataracts.

However these conditions can be improved with proper musculoskeletal care.

Our approach to vision is first to determine whether your current lens prescription adversely affects the body. We call this :visual strain”, or “visual induced strain.”

If we find that your current lens prescription does adversely affect your body, that is, cause a strain in your body, then we modify that lens prescription so that the strain is eliminated.

This is done using a technique pioneered by Dr. Joseph Field, an osteopathic physician, and Dr. James Mancini, an optometrist.

It is a simple matter to test your current lens prescription by monitoring the body’s response to that prescription. This can be done by monitoring any part of the body with your glasses on and off. However, we monitor the cranium, and the lens’ effect on the cranial mechanism.

Your current lens prescription, if appropriate, should not have an effect on the cranial mechanism. If your current prescription does have an effect on the cranial mechanism, this will affect the structure and function of the entire body, and over time, your health.

You may ask “why isn’t my optometrist or ophthalmologist aware of this?” The answer is quite simple. The average optometrist or ophthalmologist is not trained to evaluate vision in this way. The average optometrist or ophthalmologist has no way of knowing whether the glasses they prescribe are causing a strain in the body.

The average optometrist or ophthalmologist has not been trained to evaluate the effect of visual strain on the musculoskeletal system. They have no training in the consequences of prolonged visual strain on causing musculoskeletal strain, and therefore, not knowing that there is a problem, have no training in eliminating the strain.

When an optometrist or ophthalmologist prescribes lenses, they are asking you to respond verbally, asking you to indicate that an image you see is clear. People may see clearly but still have significant strain in the body.

It is not uncommon for an optometrist or ophthalmologist to provide different prescriptions for the same patient.

In my experience, the most sever visual strains are present in those people who have been prescribed lenses or have undergone LASIK surgery for monovision. In that case, the lenses or the eyes themselves are corrected so that near vision is clear in one eye, while far vision is clear in the other eye. I have not seen one case where this procedure has not caused significant visual and bodily strain.

When the Field-Mancini technique is utilized, and visual strain is eliminated, it is not uncommon for vision to improve dramatically over time, even to the point where someone who has worn corrective lenses all their lives will be able to reduce their lens prescription or even eliminate the need to wear glasses altogether.
