What are Thick Glasses?

Back in the day, thick glasses were preferred the common way of improving eyesight. It was believed and it usually happened that the stronger your prescription the thicker your glasses would be. But now with technological advancements, you get both thin and thick glasses on the same prescription. With the latest trend of high-index glasses, you get attractive and comfortable glasses that give the utmost clarity in vision.

Why are thick glass lenses so thick?

I am wondering why some lenses are thick while others are thin. Well, it may be hard to accept, but it’s true that the stronger your prescription the thicker glasses you get.

Let’s understand why this happens.

People with short-sightedness are prescribed lenses that are thicker at the edges and thinner in the middle. While the opposite happens for those with long-sightedness. Diopters are used to measure the refractive errors of your eyesight and as the measurement increases, you get a thicker lens. In some cases, people get lenses that are so thick that they might even distort their looks.

What are High-Index Glasses?

Manufactured to have a thinner edge and lighter weight, a high index lens is a lens that has a higher “index” of refraction. This clearly means they have a high ability to bend light rays and offer a sharper vision to people with stronger prescription glasses.

With the advancement in technology, eye care professionals can give you sleek and slim glasses with the same eyesight correction but without a bug-eye look. This is because high-index glasses have already captured the market to give you comfortable eyewear. They come with an aspheric design, attractive profile, and slimmer look. These glasses have a unique ability to allow more light to bend efficiently and hence these are thinner than traditional glasses. Same way, thinner lenses require fewer number lenses and therefore these glasses are lighter as well. Due to these two prime features, these glasses are way too comfortable than traditional clunky thick glasses.

Thick Glasses vs High-Index Glasses

Refractive index is the ratio of the speed of light in air to the other medium. Simply the higher will be this index more light will bend in and the less thick the glasses would be. High-index glasses are more efficient in bending lights and hence these are thinner than traditional eyeglasses. High-index glasses are therefore lightweight and are comfortable on your nose. Whereas, the traditional coke-bottle glasses are made out of less refractive material and are much heavier. Standard lenses have a 1.5 index whereas the thinnest glasses are 1.74 indexes that offer better looking and comfortable eyeglasses.

Anti-reflective Coating for High-Index Glasses

As now we know what high-index glasses are and why these are the comfortable option, we also need to know some other technicalities. It is known that all glasses tend to block some light and reflect them. Due to which it causes distraction and reduces clarity in vision. Conventional glasses reflect 8% light whereas high-index glasses reflect nearly 50% light. This makes it quite risky especially while driving at night.

As a solution apply anti-reflective coating on your high-index glasses to allow all light to pass through thereby improving vision. This gives an aesthetically pleasing look and eliminates lens reflection and allows others to see your eyes.

How do I know if high index glasses are an ideal choice for me?

High index glasses are ideal for you or not basically depending on your prescription and lifestyle needs.

If you have a prescription that is less than +/-2.00 then you may not need high index lenses, however, if you have a strong prescription higher than +/-2.00 then your doctors will recommend you this type of lenses for your regular or reading eyeglasses.
