• Diagnostic Tests: Comprehensive eye exam to determine prescription strength and lens type.

Procedure Description

1. An eye care professional will conduct a thorough eye exam.
2. Measurements of the eye's curvature and refractive errors will be taken.
3. The correct lens type and prescription strength will be chosen.
4. The lenses will be custom-manufactured and then fitted into the existing or new eyeglass frames.
5. Final adjustments to ensure a proper fit and clear vision.
