Question
Are eyeglasses made with “high index of refraction” materials thin or thick?
Step 1
The refractive index of a material is a measure of how much it can bend or refract light. \[ n = \frac{c}{v} \] where \(n\) is the refractive index, \(c\) is the speed of light in a vacuum, and \(v\) is the speed of light in the material. Show more…

If a nearsighted person wants thinner eyeglasses, is a higher or a lower index of refraction for the lenses recommended?
Coating Eyeglass Lenses. Eyeglass lenses can be coated on the inner surfaces to reflection of stray light to the eye. If the lenses are medium flint glass of refractive index 1.62 and the coating is fluorite of refractive index $1.432,$ (a) what minimum thickness of film is needed on the lenses to cancel light of wavelength 550 nm reflected toward the eye at normal incidence? (b) Will any other wavelengths of visible light be cancelled or enhanced in the reflected light?
What is the index of refraction of a clear material if a minimum of 150 $\mathrm{nm}$ thickness of it, when laid on glass, is needed to reduce reflection to nearly zero when light of 600 $\mathrm{nm}$ is incident normally upon it? Do you have a choice for an answer?
