Thin Lenses
What Thin Lenses Are
Thin lenses use a higher refractive index material (1.56) compared to standard CR-39 plastic (1.49). The higher refractive index means light bends more efficiently through the material, allowing the lens to be made thinner while providing the same optical correction. For prescriptions between -2.00 and -4.00 (or equivalent plus powers), standard lenses can appear noticeably thick at the edges. Thin lenses solve this by reducing edge thickness by approximately 20-30%, resulting in a sleeker profile that looks better in all frame styles.
Key Benefits
- 20-30% thinner than standard CR-39 plastic lenses
- Noticeably lighter weight for improved all-day comfort
- Better cosmetic appearance — no thick edges showing through frames
- Compatible with all frame styles including rimless and semi-rimless
- Improved aesthetics for moderate to moderately-high prescriptions
- Same optical clarity as standard lenses
Who Should Use Thin Lenses
Thin lenses are recommended for anyone with a prescription power between -2.00 and +2.00 who wants a slimmer, more attractive lens profile. They are especially beneficial for people who wear rimless or semi-rimless frames where lens edge thickness is visible. If your current glasses feel heavy on your nose or you are self-conscious about thick lens edges, thin lenses provide an affordable upgrade.

Frequently Asked Questions
How much thinner are thin lenses compared to regular?
For a typical -3.00 prescription, thin lenses (1.56 index) are approximately 20-30% thinner at the edges compared to standard 1.49 index lenses. The visual difference is noticeable, especially in smaller frames.
Should I choose thin or ultra-thin lenses?
For prescriptions between -2.00 and -4.00, thin lenses (Rs 100) provide a good balance of thinness and value. For prescriptions above -4.00, ultra-thin lenses (Rs 350, 1.61 index) are recommended for the best cosmetic result.
Do thin lenses affect optical quality?
No. Thin lenses provide the same optical clarity and accuracy as standard lenses. The higher index material simply allows the same correction in a thinner profile.
