Choosing the right prescription lens can be confusing—especially when deciding between 1.60 vs 1.67 high-index lenses. For patients in Glendale Heights comparing options for lens thickness, clarity, weight, and frame fit, it’s important to note that 1.67 lenses are generally thinner, while 1.60 lenses offer an excellent balance of comfort, cost, and appearance for most moderate prescriptions. At iDoctor, we guide every patient through these choices using advanced lens measurement technology and boutique optical expertise.
If you value both look and comfort in your eyeglasses, or if you have a strong prescription and want thinner lenses for your favorite designer frames, iDoctor’s optician team can help. As a leading eye doctor in Glendale Heights, we are minutes from Bloomingdale, Glen Ellyn, Carol Stream, and Addison, with a reputation for detailed care and honest advice. For designer eyeglasses in Glendale Heights or surrounding neighborhoods, the best lens is personalized to your prescription and style—not just the thinnest available.
What the service is
Understanding 1.60 and 1.67 High-Index Lenses
High-index prescription lenses are made from materials that bend (refract) light more efficiently than standard plastic or polycarbonate. The number—1.60, 1.67—refers to the refractive index. The higher the index, the thinner your lenses can be for the same prescription and frame size. This means less visible edge thickness, especially for stronger prescriptions. For example, 1.60 lenses typically reduce thickness by about 20% compared to standard plastic, while 1.67 lenses can reduce it by up to 30–40% depending on prescription and frame shape.
- 1.60 high-index: Excellent all-around option for moderate prescriptions. Good balance of thinness, durability, and clarity.
- 1.67 high-index: Ideal for stronger prescriptions and patients prioritizing maximum thinness, particularly with full-rim or small designer frames.
Comparing Thickness and Cosmetic Results
The cosmetic advantage of high-index lenses is most noticeable when you have a higher prescription, thicker edges, or want thin lenses in stylish frames. Here’s a general range (values can vary by frame and design):
- 1.60: About 20% thinner and lighter than standard plastic; strong value for many everyday glasses in the ±3D to ±6D range.
- 1.67: About 30–40% thinner than plastic; noticeably less edge thickness for prescriptions stronger than ±5D or when thickness would otherwise show.
Frame shape and lens diameter also play a big part. Smaller or rounded frames always make lenses look thinner, while oversized frames may reduce the cosmetic difference between 1.60 and 1.67.
Optical Clarity: Is One Material Sharper?
Clarity in glasses is determined both by the lens material’s optics and its surface treatments. In practice:
- 1.60 lenses: Typically have a slightly higher Abbe value (a measure of optical clarity) for less chromatic aberration. Many sensitive wearers find vision a touch sharper, though most don’t notice a difference in everyday use.
- 1.67 lenses: Sometimes show more minor color fringing in the periphery—mainly at very high prescriptions or for users who are sensitive to optical artifacts. The difference is subtle and usually outweighed by the cosmetic advantage in thicker prescriptions.
If you want to learn about chromatic aberration and how lens fit can help, see our post on why high-index lenses can show color fringes.
Weight and Everyday Comfort
Both 1.60 and 1.67 high-index lenses are lighter than standard plastic because less material is used, but the overall weight saved is often not dramatic unless the prescription or frame is especially large. Lens coatings, such as anti-reflective or blue light filters, can add tiny amounts of weight, but comfort is mostly affected by fit and lens thickness.
Prescription Suitability and Frame Compatibility
- 1.60 lenses: Preferred for mild to moderate single-vision or progressive prescriptions (often ±3D to ±6D). Work well in most designer or boutique frames.
- 1.67 lenses: A go-to for strong prescriptions (beyond ±5D or ±6D), especially when edge thickness is a cosmetic concern in slim or rimless frames.
Designer frames at iDoctor are measured digitally to make sure your lens choice matches the frame’s style and doesn’t compromise comfort or appearance. Frame compatibility is evaluated for every patient, not just those with high prescriptions.

FAQs
Are 1.67 lenses always a better choice than 1.60?
Not for everyone. 1.67 is thinner and can look less bulky in strong prescriptions, but 1.60 often provides better value, clarity, and comfort for most daily glasses with moderate prescriptions. The best choice depends on your prescription, frame, budget, and personal priorities.
Do 1.67 lenses increase the risk of glare or reflections?
Both lens types should include anti-reflective coatings, especially in higher prescriptions. 1.67 can be more prone to color fringing at the edge, but modern coatings like Crizal or Varilux help minimize this for most users. Discuss with your optician if you are particularly sensitive to glare.
Which lens is recommended in a large, bold designer frame?
If you have a strong prescription and want to wear larger frames, 1.67 may offer a slimmer edge. However, for lower prescriptions or petite frames, 1.60 is often more than adequate. It’s smart to let your optician evaluate frame size and prescription together for best results. For more tips, check out our post on luxury frame shapes for strong prescriptions.
