OPTICAL ABERRATIONS OF THE NORMAL EYE
Human eye consists of many optical parts and produce a optical system. It has a lower degree of imperfection, which is also called Aberration. Human eye takes over those defects…
AXES AND ANGLES OF THE EYE
The human eye is a complex optical system with multiple axes and angles. Varieties of axes and angles of the eye have been defined over the years. Some of the…
Interference
When two waves of light travel along the same path, the effect produced depends upon whether or not the waves are in phase with one another. If they are in…
Schematic Eye and Reduced Eye
Schematic eye:- Schematic eye is a physical or mathematical model that represents the basic optical feature of the real eye. Objectives:- To provide a basis for the theoretical studies of…
EYE AS AN OPTICAL INSTRUMENT
WHAT IS AN OPTICAL INSTRUMENT? OPTICAL INSTRUMENTIS A DEVICE THAT BASICALLY PROCESSES AND MANAGES LIGHT WAVES TO MAKE THE IMAGE CLEAR AND MAGNIFIED.OPTICAL SYSTEMS USE TRANSPARENT MATERIALS WITH REFRACTIVE INDEX…
REFRACTION OF LIGHT
Definition: It is the phenomenon where the direction of light is changed when it crosses the boundary between two mediums of different optical density. Or, in other way we can…
Measurement Of Light
LIGHT : Light is electromagnetic radiation that can be detected by the human eye. Electromagnetic radiation occurs over an extremely wide range of wavelengths, from gamma rays with wavelengths less…
