If you have a strong or complex prescription then it is extremely important that you select the correct high index lenses, as they will determine the overall thickness of your glasses.
Unfortunately, choosing the right high index lenses is not that simple. With such a wide variety of lenses to choose from, many people do not understand the differences between them. Some people are not even aware of all the options available, as many high street opticians and online stores only offer a limited choice of lenses. In this article, we explore all the various high index lenses available, so that next time you purchase glasses, you choose the right high index lenses.
Last time you bought glasses were you offered a choice between thin lenses, ultra thin lenses, or even mega thin lenses? Did you understand the differences between them? The problem is that there is so much ambiguity. In other industries, it is clearly defined. For example, if you were booking a flight, it is obvious that a premium economy seat will give you more leg room than a standard economy seat. If you want a fully reclined sleeper seat then you need to choose either business or first class.
The correct way to compare the thickness of lenses is by their refractive index. The refractive index of a lens starts at 1.5 and goes all the way up to 1.9. The higher the index, the thinner the lens will turn out. Essentially there are three types of high index lenses to choose from, and they are all available in a wide range of indexes:
It is also important to understand about the quality of the lenses you are buying. While it may be tempting to purchase cheap unbranded lenses you should avoid this where possible. Your eyesight is extremely important, why take unnecessary risks by buying lenses which may be low-quality and damaging to your sight? There are many high quality lens manufacturers to choose from. Nikon, Seiko, Essilor, Zeiss, Hoya and Corning are just some trusted names to look out for. These manufacturers have been in the business for years and have spent a lot of time and money investing in the latest thin lens technologies to ensure that their products are of the highest quality. All their lenses come with a full peace of mind warranty.
Do your homework, make sure you understand which index of lense you are purchasing, and then find out the brand. This will ensure that you get right lenses for you.
