Peripheral visions refer to the part of our visual field that is outside of our focal point. The word "peripheral" is spelled /pəˈrɪf(ə)r(ə)l/ with the primary stress on the second syllable (ə) and the secondary stress on the last syllable (rəl). The letter "r" is pronounced twice in the word, and the vowel sound in the first and third syllable is the schwa sound (ə). The word "visions" is spelled /ˈvɪʒ(ə)nz/ with the primary stress on the first syllable and the secondary stress on the last syllable (ənz).
Peripheral vision refers to the visual field outside of the direct line of sight or central focus. It encompasses the ability to detect and perceive objects, movement, and other visual stimuli that are present in the outer edges of one's visual field. Peripheral vision is essential for maintaining situational awareness and detecting potential threats or changes in the environment.
The human eye has a field of view of approximately 180 degrees, but only a small portion of this is actually in sharp focus, known as the central vision. The remainder of the visual field, which is in less detail, falls under peripheral vision. This visual capability enables individuals to see objects and movements without directly looking at them. It allows for a wider scope of awareness and aids in spatial orientation.
The peripheral visual field is characterized by lower visual acuity and diminished color perception compared to central vision. It is highly sensitive to motion, contrast, and changes in brightness, making it particularly useful in situations where quick reactions are required, such as sports or driving.
In the context of cognitive processes, peripheral vision also refers to the ability to be attentive and aware of information or ideas that may not be the primary focus of one's attention. This broader awareness can aid in creativity, problem-solving, and understanding complex situations by taking into account additional perspectives or factors that may not be immediately apparent.
The word "peripheral" comes from the Late Latin word "peripheria", meaning "circumference". This Latin word was derived from the Greek word "periphereia", which also means "circumference" or "surrounding region". The word "vision" comes from the Latin word "visio", meaning "sight" or "vision". Together, "peripheral vision" refers to the ability to see objects or events that are outside the direct line of sight or focus.
