I paid extra for Super Thin Lenses – why do they still look ridiculous?

Have you ever paid extra for thinner lenses but still been unhappy with how your glasses turned out? Let’s paint the picture… After your eye test you have been whisked into the equivalent of a car showroom and pressurised to try on new frames. Once you’ve finally chosen one, you are advised to go for top of the range Super Thin Lenses which of course cost a fortune. But you think – even though it’s expensive, it will be worth it in the end because the optician has told me these are the thinnest lenses available.  Then when you return a fortnight later to pick up your new glasses you are astonished at how thick the lenses have actually come out.  Does this sound familiar?

Here is a quick guide to help make sure that you end up with a pair of glasses you will be proud to wear:

First of all, don’t just take their word for it when they say you will be getting their top of the range Super Duper Thin Lenses. The problem is that there is so much ambiguity on the high street. It can be a mine field knowing whether Ultra Thin lenses from one store will give you a better result than Super Thin Lenses or even Mega Thin Lenses from a rival store.  This is all marketing hype to prevent people from comparing like for like. 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:

  • Plastic High Index Lenses (most common). They are available in 1.5, 1.61, 1.67 and 1.74 indexes. Where 1.5 is the thickest lens available and 1.74 is the thinnest. Click here for more information.
  • Double Aspheric Lenses or DA Lenses are also made of plastic. However they are thinner and flatter than standard plastic high index lenses. They are available in 1.61 DA, 1.67 DA  and 1.74 DA indexes. Where 1.61 DA lenses are the thickest, and 1.74 DA are the thinnest Double Aspheric lenses available. Click here for more information.
  • Glass High Index Lenses are available in 1.5, 1.7, 1.8 and 1.9 indexes.  With 1.5 being the thickest lens and 1.9 being the thinnest available. Click here for more information

 

Secondly, it is also important to understand about the quality of the lenses you are buying. 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.

Finally, not only do you need to select the right lenses for your prescription but you also need to select the right type of frame. This combination of lenses & frame choice is especially important for people with strong or complex prescriptions. This will ensure that your lenses do not stick out from the edge of the frame or embarrassingly bulge in the middle, so you will see the true benefit from the High Index lenses you have purchased.

Do your homework, make sure you understand which index of lens you are purchasing, and then find out the brand. This combined with the correct type of frame will make sure that you end up with a great looking pair of glasses.
