Technology Devices to Overcome the Limitations of Sight and Hearing Humans have sight and hearing limitation. Without any devices‚ our sight and hearing was limited. Most of the limitation of sight can be overcome with the help of certain optical instruments such as magnifying glass‚ microscope‚ binoculars and others. The range of frequency of hearing in human 20 Hz to 20 000 Hz. It was different according to the age of a person. Hearing limitations can be overcome by using devices such as

different on the pocket microscope? The total magnification in a light microscope is the product of the ocular and objective lenses. Suppose Ocular is of 10x Objective lens is of 40 x. Total magnification will be 10X40=400. For pocket Microscope M= (LENGHT OF MICROSCOPE TUBE)/(focal length OF EYE PIECE)*(focal length of objective lens) 2. What parts of a compound light microscope can be used to control the amount and intensity of light reaching the object being examined? How is the pocket microscope

back to their original energy levels‚ they emit lower-energy and longer-wavelength light. Inverted‚ confocal‚ and polarized light microscopes are industrial microscopes. An inverted microscope locates the illumination system above the stage and the lens system below the stage. A confocal microscope or laser microscope uses a laser-to-light image one plane of a specimen at a time. Polarized light microscopes use two polarizers. These polarizers are perpendicular to each other so that only light which

Case Report Clinical Assessment of a Patient With Compound Myopic Astigmatism and Convergence Insufficiency Abstract Myopic astigmatism is a specific type of astigmatism wherein the light focuses before it reaches the retina. This condition is classified as a combination of astigmatism and myopia‚ or nearsightedness. If both principal meridians are nearsighted‚ but one is more pronounced than the other‚ it is considered to be a compound myopic astigmatism. Convergence Insufficiency on

Eye Donation Introduction We are one of the fastest growing economies in the world today; ironically‚ we also shoulder one of the largest populations of the visually impaired. There are almost 52 million visually impaired people and 270‚000 blind children in India. That’s almost one-fourth the world’s blind population living in India. For the more academically oriented‚ as some economist pointed out‚ this could mean a cumulative loss of over $ 11.1 billion to our GNP! It is this kind of a grave
