Having trouble figuring out all the options? We have the answers you may be looking for on this page that will help you make a better educated decision when choosing your prescription lenses.
The recommendations on this page are based on the general public and are not recommended for everyone. For the best lens recommendations please consult with your eye doctor.
Thinnest LensesThe common rule is the higher the index, the thinner the lens. Standard CR-39 Plastic is the thickest lens but offers the least amount of distortion. For this reason, Anti-glare coating is recommended on any Hi-Index material lens and is included on all 1.70+ index lenses to help reduce distortion. Listed below are from thinnest to thickest.
- Hi-Index 1.74: Up to 50% thinner than CR-39 plastic. Thinnest lenses currently offered includes anti-glare coating. Well suited for prescriptions over 5.00 SPH (+/-). The real difference can be noticed over powers of 8.00 (+/-).
- Hi-Index 1.70: Up to 45% thinner than CR-39 plastic. Well suited for prescriptions over 5.00 SPH (+/-).
- Hi-Index 1.67: Up to 42% thinner than CR-39 plastic. Suited for prescriptions over 2.50 SPH (+/-).
- Hi-Index 1.60: Up to 30% thinner than CR-39 plastic. Suited for prescriptions under 2.50 SPH (+/-).
- Polycarbonate 1.59: Up to 30% thinner than CR-39 plastic. Suited for prescriptions under 2.50 SPH (+/-).
- CR-39 Plastic 1.49: Standard CR-39 Plastic lenses. Currently the thickest lens offered.
- Anti-glare coating is recommended to help reduce lens distortion. It is strongly recommended when purchasing Hi-Index material or Progressive lenses. The Crizal® brand is recommended for durability, performance and it's easability in cleaning.
- Polarized Lenses: Generally dark and reduces glare from surfaces (ie: water) & objects. Offers much better vision under the sun than normal tinted lenses.
- Standard CR-39 Plastic Lenses: Recommended for dark color tinting only (for non-polarized lenses). The CR-39 material is the best tintable option whereas other materials may not offer dark tinting.
Children, Sports & Safety Lenses
- Trivex or Polycarbonate lens materials are recommended for safety reasons. Trivex is stronger than Polycarbonate but may present more vision distortion.
- Varilux®, Essilor®, or Zeiss® lenses are recommended. These particular brands offer less distortoin and better overall vision than other progressive lenses offered.
Reading & Computer Lenses
- 10% Rose tint is usually suggested to help from tiring the eyes due to reading.
