In addition to rehabilitation therapy, we help concussion patients with specially designed lens prescriptions that address the patient's specific problems.
Many concussion patients respond well to particular lens prescriptions such as low plus or reduction of minus lenses. it is thought that the small changes in magnification created by these kinds of lens prescriptions cause changes in preceived motion that lead to a decrease in symptoms of disequilibrium, dizziness and motion hypersensitivity.
Other successful lens applications that we have used with concussion patients include binasal occlusion, low base in prism, and tints that may decrease the contrast and thus also lessen symptoms of motion hypersensitivity.
In addition to the foregoing, a concussion patient's vision correction needs may change drastically and they may not be able to wear that contact lenses and spectacles that they wore before the concussion.
For example, patients that are used to wearing multifocal or progressive lenses may have problems after a concussion. After a concussion, many patients are more sensitive to the motion in the multifocal or progressive lenses. Patients who used monovision or bifocal contact lenses before the concussion may no longer be able to tolerate them. It might be better for these patients to switch to separate single vision lenses for far and near. Alternatively, we may prescribe contact lenses for far and contact lenses with reading lenses for near.
