Introduction:
The retina, the neural component, is one of the principle components of the eyeball. It consists of three cell layers, and these cell layers are composed of ganglion cells, bipolar cells, and photoreceptor cells. The photoreceptor cells are involved in the absorption of light and produce an electrical or chemical signal. These cells are of three kinds, and they are cones, rods, and some ganglion cells. These cone and rod cells generate visual images, and these cells are related to ependymal cells present in the brain.

Suppose you measure the scanning (4x) field of vision diameter with a stage micrometer and it is 2 mm. If high power is 40X, and gives 10X more magnification than scanning power, how big will the diameter of the field of vision be using high power?
A typical incandescent lightbulb emits approximately 3 x 1018 visible-light photons per second. Your eye, when it is fully dark adapted, can barely see the light from an incandescent lightbulb 10 km away. How many photons per second are incident at the image point on your retina? The diameter of a dark-adapted pupil is 6 mm.
Very short pulses of high-intensity laserbeams are used to repair detached portions of the retina of the eye. Thebrief pulses of energy absorbed by the retina weld the detached portionsback into place. In one such procedure, a laser beam has a wavelengthof 810 nm and delivers 250 mW of power spread over a circularspot 510 mm in diameter. The vitreous humor (the transparent fluid thatfills most of the eye) has an index of refraction of 1.34. If the laser pulses are each 1.50 ms long, how much energy is delivered to the retina with each pulse?

- Occupational Hearing Loss Frequent exposure to loud noise of a particular pitch can cause loss of hair cells in the part of the cochlea that responds to that pitch. People who work with or around noisy machinery are at risk for such frequency-specific hearing loss. Taking precautions such as using ear plugs to reduce sound exposure is important. Noise-induced hearing loss can be prevented, but once it occurs it is irreversible because dead or damaged hair cells are not replaced. FIGURE 33.24 shows the threshold decibel levels at which sounds of different frequencies can be detected by an average 25-year-old carpenter, a 50-year-old carpenter, and a 50-year-old who has not been exposed to on-the-job noise. Sound frequencies are given in hertz (cycles per second). The more cycles per second, the higher the pitch. FIGURE 33.24 Effects of age aria occupational noise exposure.
