Understanding Refractive Index in Prescription Lenses
Refractive index refers to the measure of how much light is bent or refracted as it passes through a medium, such as glass or plastic. In the context of eyewear, it indicates the optical density of the lens material.
Range of Refractive Index
- 1.499 to 1.9: Refractive indexes for prescription lenses typically range from 1.499 to 1.9.
- Higher Index, Thinner Lenses: As the refractive index increases, the lenses become thinner, making them more aesthetically pleasing and comfortable to wear.
Importance in Lens Selection
- Prescription Requirements: The choice of refractive index depends on the individual’s prescription. Higher refractive indexes are recommended for stronger prescriptions to reduce lens thickness and weight.
- Frame Compatibility: Refractive index also influences lens thickness in relation to the chosen frame style. Our knowledgeable staff will assist in selecting the most suitable lens material for your prescription and frame.
