Question

the relationship between spectacle refraction and ocular refraction

Answer 1

spectacle refraction versus ocular refraction. HYPEROPIA When a parallel rays of light coming from infinity are focused behind the retina due to the abnormality between therefractive power of the eye and the axial length of the eye is known as hyperopia.

Answer 2

1.refraction is the change in direction of a wave passing from one medium to another or from a gradual change in the medium.

2.refractive index or index of refraction of a material is a dimensionless number that describes how fast light travels through the material. It is defined as. where c is the speed of light in vacuum and v is the phase velocity of light in the medium.

3.Total internal reflection when refraction reflection at critical angle and refraction takes place called TIR
