High index lenses can be quite expensive, depending on the optics and features you are looking for. Single vision lenses, for example, come in four index materials and have varying prices. The higher indexes are thinner than the lower indexes and may cost 25-30% more.
If you need a more advanced lens type such as progressive lenses, high index materials may cost 50-100% more than the entry-level materials. Additionally, lens coatings and tints are generally extra charges, and high index lenses are more likely to require these to offer the best vision performance.
In general, if you want the thinnest lenses possible, you will need to pay a premium for high index lenses.

How much do high index glasses cost?
The cost of high index glasses will vary depending on a few factors, including the type of treatments and lenses you select, the frame you choose, and the specific style of your glasses. Generally, the cost for a single pair of glasses with high index lenses is around $200 to $400 though it can be higher or lower depending on the aforementioned factors.
For instance, if you opt for designer frames or add features such as anti-glare, transitional lenses, or ultraviolet protection, you can expect to pay more for your glasses. Also, progressive lenses tend to add additional cost.
The type of high index lenses you choose will also affect the total cost. For example, the thinnest 1. 74 index lenses are the most expensive, while a 1. 67 variety is slightly lower. In any case, your optometrist will be able to provide you with more accurate pricing information based on your specific needs and preferences.
What are the disadvantages of high index lenses?
High index lenses are lenses made of materials that are thinner and lighter than conventional lenses. While high index lenses offer several benefits, such as improved optical clarity and better eye protection, there are also some potential disadvantages that should be considered before purchasing a pair of these lenses.
The most significant disadvantage of high index lenses is the cost. Because these lenses are made from materials that are thinner and lighter, they are more expensive than conventional lenses. Additionally, high index lenses may not be coated with various treatments, such as anti-reflective and ultraviolet coatings, which can increase the cost of the glasses even more.
Another potential disadvantage is that the desired level of comfort and clarity may not be achieved with high index lenses. The extra thinness of these lenses can sometimes cause distortion or fuzziness, which can lead to eye strain, headaches and lack of vision sharpness.
People with higher prescriptions, such as those with greater than +/-3. 00, are more likely to experience these issues.
In addition to the potential distortion, high index lenses may cause a “calgary effect”, which is when the lenses appear to have a slight tint of the frame color when looking through them. This is caused by a mismatch between the index of refraction of the lenses and the frame material, and is a common issue with higher-index lenses.
Finally, depending on the materials used, high index lenses may also be more fragile and prone to scratches than conventional lenses. This is especially true if the lenses are not treated with a scratch-resistant coating.
In summary, there are several potential disadvantages associated with high index lenses. These include a higher cost, the potential for distortion and clarity issues, the calgary effect, and increased fragility.
It is important to weigh these considerations against the potential benefits of these lenses before making a purchase.
At what prescription are high index lenses recommended?
High Index lenses are recommended for people who have a prescription of -3. 00 diopters or more for distance vision and +3. 00 diopters or more for near vision. High index lenses are a specialty lens material designed to be thinner and lighter than traditional plastic lenses.
The components of high index lenses allow for a lens that is much thinner and lighter than standard plastic lenses and can help reduce the size and the weight of eyeglasses. This type of lens material is intended to help people who have a strong prescription and who, therefore, would otherwise wear thick, heavy lenses.
The overall advantages of high index lenses over traditional plastic lenses include improved vision, more comfortable eyewear and a more fashionable look. High index lenses can also help reduce eyestrain, as the reduced thickness of the lens allows for more light to pass through it.
Do higher prescription glasses cost more?
Yes, higher prescription glasses generally cost more due to the type of lenses and frames used. The lenses and frames of glasses are the largest cost in glasses, and when you factor in higher prescription lenses, the price of the glasses goes up significantly.
Higher-level prescription glasses typically require specialized lenses and thicker, more advanced frames to provide the necessary amount of protection for your vision. The thickness and type of lens material used for high-level prescription glasses can bump up the cost quite a bit.
Additionally, special coatings and treatments may need to be applied to the lenses and frames to improve durability, clarity, and other factors related to vision health, which can contribute to the overall cost.
Is there a big difference between 1.67 and 1.74 high index lenses?
Yes, there is a big difference between 1. 67 and 1. 74 high index lenses. High index lenses are among the thinnest lenses available, and the higher the index, the thinner and lighter the lenses are. The higher number means that 1.
67 lenses are thinner and lighter than 1. 74 lenses, making them comfortable and more aesthetically pleasing to wear. They have less curvature on the edges, which creates a more modern, streamlined look.
They also reduce the thickening of the lenses as the power increases, making them less visually noticeable when you’re wearing them. Thus, if you are looking for the thinnest lens possible and can afford the additional cost of a higher index lens, 1.
67 lenses will provide you with the most benefits.
Does Costco offer 1.74 high index lenses?

If you would like a quote specific to your eye prescription and needs, it is best to contact your local Costco and discuss the costs with an optician.
Are 1.74 lenses the thinnest?
No, 1. 74 lenses are not the thinnest lenses available. There are lenses available that are even thinner than 1. 74 lenses. For example, lenses as thin as 1. 67 can be made with the latest ultra-thin lens technology.
These lenses provide superior optical clarity and a thinner, lighter profile than traditional lenses. Other even thinner lenses are available, including 1. 6, 1. 56, and even 1. 53 lenses. These lenses use the most advanced materials and manufacturing processes to create a lens that is thinner and more durable.
How much should I pay for prescription lenses?
The cost of prescription lenses depends on several factors, including the type of lenses you choose, the type of frames, and the complexity of your prescription. Generally, regular plastic single vision lenses can cost anywhere from $25 to $100, while high-index (thinner) lenses can cost a lot more.
If you need more complex vision correction, such as bifocal or progressive lenses, the cost will be even higher. Some brands may also offer discounts for specific prescriptions or if you choose to purchase additional features like anti-reflective coating or scratch-resistant lenses.
It’s important to remember that high-quality lenses don’t necessarily have to be expensive and there are a variety of professional optical labs that offer affordable prescription lenses. Ultimately, the best way to determine a cost is to consult with your eye care professional and discuss your options.
Is 1.74 the highest index lens?
No, 1. 74 is not the highest index lens. The current highest index lens available is 1. 9, which is about 25% thinner than 1. 74 lenses. These lenses are excellent for those who have strong prescriptions, as they are able to make their glasses thinner, lighter and more comfortable.
Furthermore, they help reduce any distortion caused by the lens with a higher power, making them a great choice for those who want the best vision possible.
Is there anything thinner than 1.74 high index?
Yes, there are lens materials that are thinner than 1. 74 high index. Polycarbonate and Trivex lenses are both available in 1. 67 index, which makes them even thinner than 1. 74 lenses. Additionally, many 1.
67 lenses are made with AR coating to further reduce distortional aberrations to sharpen vision. 1. 6 high index lenses are even thinner, with hybrid materials that often combine polycarbonate and other materials for added strength and durability.
However, in general, 1. 6 lenses degrade image quality more quickly than 1. 67 or 1. 74 lenses. So, if your priority is for thinner lenses with the greatest optics, 1. 74 high index is likely your best bet.
What is considered a high prescription for glasses?
A high prescription for glasses is usually defined as one that requires lenses with higher than average optical power. Generally, a prescription is considered to be high if the power of the lenses is greater than +6.
00 diopters for distance vision or +4. 00 diopters for near vision. It is important to note that the exact threshold can vary from one optometrist or ophthalmologist to the next, as some may consider prescriptions higher than +4.
00 for near vision to be high, while others may use a higher cut-off. In cases where a very high degree of visual correction is required, specialty lenses or complex lens designs may be necessary to optimize vision.
