Have you ever heard of lenses 1.67 or 1.74? These are special kind of lenses, which people use in their prescription glasses! In this article we will look at the difference between these two lens types. We’ll also help you choose which one is the better fit for you. Join me as we learn more about 1.67 and 1.74 lenses!
We will need to establish what high index lens are before we talk about the 1.67 and 1.74 lenses. High index lenses are made from a special type of material that allow the lenses to be thinner than regular lenses. This is excellent for those with stronger prescriptions, as it lightens and thins the glasses.
Also, high index lenses may fit comfortably on your face. Thicker lenses can feel heavy on your face (even if you don’t wear glasses, you can imagine that); in strong prescriptions they can also cause discomfort. But thin lenses also tend to be lighter, making them easier to wear for extended periods.
High index plastic 1.74 lenses are made from unique material. This material is used to try and make the lenses as thin and light as possible. Also because they’re so thin, 1.74 lenses can minimize a visual defect called chromatic aberration. If you look through lenses that are thicker, this problem can make images appear blurry or distorted. With their thinness 1.74 lenses can make you see things sharper with bright colors and clearer vision.
On the other hand, 1.67 lenses are made from a not-quite-so-special material. Although they are still thicker than normal lenses, they are not as skinny as 1.74 lenses. This means that 1.67 lenses are more likely than to blur that’s called chromatic aberration. 1.74 lenses are a better choice, then, if you want the clearest vision possible.
The following is a side-by-side comparison of the two lenses. But 1.67 lenses are obviously thinner and lighter than 1.74 lenses. Not only does this make them more comfortable to wear, it also makes them more visually appealing. They also make it a little easier to see, and are particularly important for those who have strong prescriptions, since they are thinner.
1.67 lenses, however, are an excellent option for those in need of high index lenses who want to not pay quite as much. They are relatively affordable and less expensive than 1.74 lenses but more expensive than polycarbonate lenses, while also slightly more durable than 1.67 lenses. They are able to handle a little more wear and tear than glasses, making them a safer choice if you are worried that you will damage your glasses.
