The shape of the eye or cornea or age-related stiffness of the lens may decrease the focusing power of the eye. Objects may appear blurry when far away, near, or both. An ophthalmologist or optometrist determines how best to correct vision.

In telecommunications, return loss is the loss of power in the signal returned/reflected by a discontinuity in a transmission line or optical fiber. This discontinuity can be a mismatch with the terminating load or with a device inserted in the line. It is usually expressed as a ratio in decibels (dB): where RL (dB) is the return ...

While light travels in a straight line and passes from one medium into another, for example from air to water, it will change speed and change direction. This is called refraction. The speed of light will change depending on the medium it travels through.
