Limitations of sight can be overcome by using appropriate optical devices such as microscope, telescope, periscope and others. Devices to overcome the limitations of sight. 1. Microscope †¢Instrument to magnify object such as virus. †¢Objective lens and eyepiece magnify image. -Types- light microscope, electron microscope 2. Magnifying glass †¢Limited magnifying power-10 to 15 times †¢Use to see small object. †¢Magnifying glass is convex lens. 3. Telescope †¢viewing distant objects -stars, planets , Moon. †¢Consists of two convex lenses- objective and eyepiece lens. †¢The image produced by the objective lens is magnified by the eyepiece lens. 4. Binoculars †¢Binoculars provide a stereoscopic vision of distant objects. †¢The parts of the binoculars and their functions are the same as those of the telescope. †¢Binoculars are actually a pair of telescope. †¢Use- watch horses running in a race 5. Ultrasound scanning device †¢ultrasonic waves create images -organ , fetus. †¢Device shaped like microphone is pressed against the area being scanned. †¢This device sends out very high frequency sound waves into the area being scanned. †¢The waves bounce back upon hitting an organ and an image of the organ is then obtained on computer screen 6. X-rays †¢X-rays can also be used to detect the condition of certain organs or detect fracture of bones. In medical X-rays, the X-rays penetrate the internal soft body tissues and form images on a film which can be examined by a radiologist
