Before we talk about refractive vision problems, let's look at how your eye works.

It is a clear oil with a refractive index of 1.5168.

The refractive index of air is close to, but just greater than 1.

This is because oil has a refractive index greater than 1.

The refractive index of water at 20 C is 1.332986.

Because glass has this great refractive quality, cutting made a lot of sense.

Many insurance companies do not cover the cost of refractive surgery.

The eye itself is filled with some sort of refractive fluid.

This movement will always go into the material of higher refractive index.

Water has almost the lowest refractive index you can find, 1.33.

The refractive index of the glass is the same everywhere.

The first lens has positive refractive power, the second negative.

It is often represented in terms of a refractive index.

In this paper he was able to show that refractive index may also be negative.

Silicon also has a very high refractive index, of about 3.5.

Persons who are thinking about refractive surgery should consider this.

The eye itself has a refractive power of 60 diopters.

He knew, from his reading, that the refractive quality of water could distort such things.

Water has a different refractive index than air, so the path of light changes its direction.

But he didn't need them; his vision was fine without refractive help.

Every natural material so far only allows for a positive refractive index.

This ratio is called the refractive index of the material.

The refractive index is basic to the science of optics.

Measurement of small differences in the refractive index between the two data states.

Refractive indices are very high, above 2.5, which is even higher than diamond at 2.42.
