1.59 Index Lenses Vs 1.6 Buying Guide
Clarity and Visual Acuity
Both 1.59 and 1.6 index lenses offer excellent clarity and visual acuity, but they cater to slightly different needs. 1.59 lenses, being more impact-resistant, are a great choice for active lifestyles and sports. They provide clear vision with a focus on safety. 1.6 lenses, while still offering good clarity, may be preferred for those needing higher prescriptions due to their thinner profile. Consider your activity level and prescription strength when prioritizing clarity.
Thickness and Aesthetics
The thickness of the lenses is a key consideration, especially for those with higher prescriptions. 1.6 index lenses are noticeably thinner than 1.59 lenses, leading to a more aesthetically pleasing appearance. This is particularly beneficial for those who are concerned about the “coke bottle” effect. 1.59 lenses, while thicker, are still relatively thin compared to standard plastic lenses, offering a balance of thickness and impact resistance.
Impact Resistance and Durability
1.59 index lenses are renowned for their exceptional impact resistance. They are significantly more durable than 1.6 lenses and standard plastic lenses. This makes them an ideal choice for children, athletes, and anyone who requires robust eyewear. 1.6 lenses, on the other hand, are less impact-resistant, although modern coatings can enhance their durability. Consider the potential for accidental damage when choosing between these two options.
Weight and Comfort
Weight plays a significant role in the overall comfort of eyeglasses. While both 1.59 and 1.6 lenses are lightweight compared to traditional glass lenses, 1.6 lenses tend to be slightly lighter due to their higher index. This can contribute to a more comfortable wearing experience, especially for extended periods. However, the difference in weight is often minimal, and other factors, such as frame design, can also impact comfort.
Prescription Range and Suitability
Both lens types are suitable for a wide range of prescriptions. However, 1.6 lenses are often favored for higher prescriptions because their thinner profile helps to minimize the “coke bottle” effect and improve aesthetics. 1.59 lenses are suitable for most prescriptions, offering a good balance of features. Consider the complexity of your prescription and your aesthetic preferences when making your choice.
Cost and Value
The cost of eyeglasses can vary depending on several factors, including the lens material and any added features. 1.59 index lenses are often more affordable than 1.6 lenses. However, the price difference might be negligible, depending on the retailer. Consider the overall value, taking into account your individual needs, lifestyle, and budget. Evaluate the pros and cons of each lens type to determine the best value for your specific requirements.

What is the main difference between 1.59 and 1.6 index lenses?
The primary difference lies in their material properties. 1.59 index lenses excel in impact resistance, making them ideal for safety and active lifestyles. 1.6 index lenses are thinner and lighter, offering improved aesthetics, especially for higher prescriptions. This choice depends on your priorities between safety and appearance.
Are 1.59 lenses suitable for sports?
Yes, 1.59 index lenses are an excellent choice for sports and other physically demanding activities. Their high impact resistance helps protect your eyes from potential injuries caused by balls, flying objects, or accidental impacts. This makes them a safer option compared to standard plastic lenses or 1.6 lenses.
Are 1.6 lenses more expensive than 1.59 lenses?
Typically, 1.6 index lenses are slightly more expensive than 1.59 lenses. This is due to the advanced materials and manufacturing processes used to achieve their thinner profile. However, prices can vary between different optical retailers and depend on any additional lens coatings or features you may choose.
Which lens is better for high prescriptions?
1.6 index lenses are often preferred for individuals with high prescriptions. Their thinner profile reduces the “coke bottle” effect, providing a more aesthetically pleasing appearance.

Can I get anti-reflective coating on both lens types?
Yes, both 1.59 and 1.6 index lenses can be treated with anti-reflective (AR) coatings. AR coatings reduce glare, improve clarity, and enhance the cosmetic appearance of your lenses. They also make your lenses easier to clean. This is a highly recommended add-on for both lens types.
Which lens is more durable overall?
1.59 index lenses are generally more durable than 1.6 index lenses due to their superior impact resistance. This makes them a better choice if you are prone to dropping your glasses or if you engage in activities where your glasses may be exposed to impacts. Consider your lifestyle when prioritizing durability.
Final Verdict
Both 1.59 and 1.6 index lenses offer distinct advantages. 1.59 lenses excel in impact resistance, making them ideal for active lifestyles and safety. 1.6 lenses provide a thinner and lighter profile, enhancing aesthetics, particularly for those with higher prescriptions. The best choice depends on individual needs and priorities.
