Advisor on Vision Information

As a trusted eye care adviser to our patients, Maxivision Eye Care in Naperville, IL is ready to help patients understand and deal with complicated eye care issues.


One of Dr. Prasod’s primary areas of clinical interest for over 15 years has been the fitting of rigid gas permeable contact lenses for patients with high astigmatism and Keratoconus.

Keratoconus is a condition where large amounts of astigmatism develop, accompanied by distortion and corneal thinning. This condition typically declines over time. As the vision of Keratoconus patients declines, neither glasses, soft contact lenses nor the expensive custom toric soft contact lenses can yield good vision.

When a gas permeable lens is placed on an eye, the optical result is excellent because it masks over and neutralizes out most distortions, irregularities and astigmatism. If you or a family member has high astigmatism and are unable to see satisfactorily with glasses or soft contact lenses (or if you have in fact been told that you have Keratoconus), then gas permeable contact lenses may be in your best interest.

Please call our office to schedule and eye examination and thorough contact lens analysis.

Amblyopia or Lazy Eye

Unevenly matched prescriptions between the two eyes can lead to the development of “lazy eye” in children. It is difficult for a parent to realize that a potential problem exists because typically only one of the child’s eyes is affected. The child seems to function well and see well, but the brain’s neurological connection to one eye can be stunted and not develop properly.

The brain requires a clear image from both eyes in order to process the visual input in such a way that the eyes grow up working in conjunction with each other.

Sometimes a relatively high prescription in both eyes can lead to “bilateral amblyopia” or lifetime uncorrectable reduced vision in both eyes.

A critical age for amblyopic development is 4 to 5 years old. Once past this age the “lazy eye” cannot gain full vision, even with the proper pair of glasses.

To illustrate the lazy eye mechanism and how the brain has critical ages for proper development of faculties, consider foreign accents. If one learns a language before 12 years of age, no accent exists. After 12, you will have an accent even with classes, practice and diligence. I can attest to this.

Since the critical age for lazy eye is 4-5 years old, I started examining my daughters when they turned 3. This is my recommendation for all children.
