Question 1

What are high index lenses?

Accepted Answer

High index lenses are lenses that bend more effectively than other types of lenses due to their higher index of refraction. They allow people with strong prescriptions to wear glasses with thinner and less noticeable lenses.

Question 2

What are high index lenses used for?

Accepted Answer

High index lenses are usually recommended for people who have significantly high refractive errors and strong prescriptions, including nearsightedness, farsightedness, and astigmatism.

Question 3

Why are high index lenses expensive?

Accepted Answer

High index lenses are made of a synthetic blend of chemicals that allow for high refractive power on lenses that are much thinner than regular ones. This material is much more expensive, which accounts for the high prices of glasses with high index lenses.

Question 4

Can anyone get high index lenses?

Accepted Answer

While anyone can wear high index lenses, they're recommended for someone who has a very strong prescription. A stronger prescription usually means thicker lenses, and using high index lenses means thinner ones.

Question 5

Do high index lenses make me see better?

Accepted Answer

High index lenses are quite powerful. They can improve more severe vision problems than traditional lenses in people with myopia.

Question 6

How long does it take to get used to high index lenses?

Accepted Answer

Typically, it will take 2 or 3 days for a person to adjust if he/she gets a new pair of glasses with high index lenses.

Question 7

Are high index lenses worth it?

Accepted Answer

Despite being more expensive than regular lenses, high index lenses are a worthwhile investment for individuals who have a high prescription because these allow them to use lenses that are much thinner than regular ones and that are much more comfortable to wear.

Question 8

What frames are best for high index lenses?

Accepted Answer

Since high index lenses are much thinner than their regular counterparts, users can choose from practically any kind of frame they like. Metal frames that are usually reserved for low prescriptions can now be used, as well as aviator glasses, which typically don’t look very good with high prescriptions with thick lenses.

Question 9

Should I get polycarbonate or high index lenses?

Accepted Answer

It depends mostly on the strength of your prescription, with high index lenses being generally preferable for more severe prescriptions. High index lenses are also thinner and more scratch resistant, but polycarbonate weighs less and does not break as easily upon impact.
