Muscle imbalances within the eyes often occur as a result of genetic factors, trauma or related conditions, and result in one eye that is stronger than the other. Eyes that do not work properly together can cause blurred, crossed or double vision. Some cases of muscle imbalance may worsen over time, which is why it is important to seek proper treatment.
Conditions Treated with Prism Lenses
- Crossed eyes
- Vision problems after a traumatic brain injury
- Double vision
Prism lenses bend light and align eyes so that they work together to produce a single image, rather than the double vision experienced by many patients with these conditions. Depending on each patient's individual needs, prism lenses can display the image in any direction to either adjust one eye or coordinate both eyes to work together.
Symptoms Requiring Prism Lenses
In addition to poor eyesight, these conditions can cause some of the following symptoms:
- A lack of depth perception
Treatment with Prism Lenses
Treatment with prism lenses can be used in glasses or contact lenses to provide advanced vision correction for patients suffering from a muscle imbalance. Prism lenses look the same as regular lenses and can be used in bifocal, trifocal or variable focus lenses so that patients can achieve full vision at all distances. Prism treatment often makes the difference between satisfactory and highly successful vision correction.
When combined with eye exercises to further manipulate muscles, many patients achieve successful correction with prism lenses. These lenses may not be needed permanently. Prism lenses are able to provide long-term correction of double vision and related conditions so that patients can go on to wear regular glasses or contacts. For some patients, prism lenses may eliminate the need for surgery to correct crossed or double vision.
