What is a Glasses Contact Lens Conversion Chart?
The glasses contact lens conversion chart is a tool that helps individuals convert their eyeglass prescriptions into contact lens prescriptions. The two types of prescriptions are not identical due to differences in how glasses and contact lenses sit on the eye. This chart takes into account several factors, such as the curvature of the lens and the distance from the eye.
How Do Glasses and Contact Lens Prescriptions Differ?
Understanding the differences between glasses and contact lens prescriptions is essential for making an informed decision. Here are some key distinctions:
- Measurement Units: Glasses prescriptions are measured in diopters, while contact lenses are measured in base curves and diameters.
- Distance from Eye: Glasses sit away from your eyes, while contact lenses are placed directly on the cornea, requiring adjustments in prescription values.
- Type of Correction: Glasses may correct for astigmatism differently than contact lenses due to their positioning.

- Consult with your eye care professional to ensure the converted values are suitable for your specific eye shape and needs.
When Should I Consult an Eye Care Professional?
