High index lenses are ideal for people who have a very high prescription. It could be a high prescription for farsightedness, nearsightedness, astigmatism or a combination.

A person who is nearsighted uses a minus lens, which is thin in the middle and thick around the edges. The higher the prescription goes, the thicker the edges become. 

For some people it is almost impossible to wear glasses with a normal index because of the weight of the glasses, plus it is not very aesthetically pleasing.

High index lenses are able to bend light more effectively, so they do not have to be so thick to correct the prescription.

Look at the difference in edge thickness of a standard index lens on the left and a high index lens on the right.

Benefits of high index lenses:

• Thinner than normal lenses.
• People with big prescriptions used to have to accept that their glasses will hurt their noses or keep on sliding down because of the weight of the lenses. Because a high index lens is so much thinner than normal, it is also a lot lighter.
• Stronger than normal index lenses, can be used for environments where safety lenses are required.
• It reduces the 'bug eyed' look
• It is ideal for rimless and semi-rimless frames frames, because they will not crack or chip as easily as normal index lenses.
• Comes in Transition, Polarized, Tinted, UV coating, Anti-reflective coating.

Drawback of high index lenses:

• Price - it is usually a lot more expensive than normal index lenses.
