A projection alarm clock is an innovative type of alarm clock that projects the time onto a flat surface. Some clocks use a screen, but many are designed to project the time onto the wall or ceiling, using numbers large enough to see at a distance or by a near-sighted person.
This is particularly useful at night when many people would need to reach for their glasses to check the time. Instead, the projection alarm clock's time is large enough to see without them. Many clocks are adjustable, so the user can make the numerals larger or smaller as necessary.
The projection alarm clock typically has other settings too where the time can be projected in different colors - red and green are among the most common, but this feature differs between models. The projection can be quite aesthetically pleasing depending on its placement and how it works with the color scheme in a room.
Additionally, the brightness of the projection can often vary between high brightness and low brightness; however, neither setting is typically so luminous as to interrupt sleep. Higher brightness settings are easier to read in a room that is not dark or dimly lit.
A user can expect the projection alarm clock to have other, more ordinary features available in addition to those relevant to its projection function. Many alarms come with a radio and volume control for that feature, along with the alarm buzzer itself. Also included is typically the snooze button and possibly a second alarm. All features vary by model, but these are among the most common.
