FOCIMETER Meaning and
Definition
-
A focimeter, also known as a lensmeter, is a specialized ophthalmic instrument used to measure the properties of lenses, such as their power, axis, and prismatic effects. It is an essential tool in optometry and opticianry, enabling accurate prescription and fitting of eyeglasses and contact lenses.
The focimeter typically consists of a viewing system that allows the operator to observe a target or scale through the lens being measured. By placing the lens in the appropriate position and adjusting various knobs and controls, the instrument can determine the lens power, astigmatism, and other optical parameters.
To measure the power of a lens, the focimeter projects a target onto the lens surface. The operator can then adjust the instrument until the target aligns, indicating the point of focus. The reading on the instrument's scale corresponds to the lens power.
Similarly, by incorporating prisms and further adjustments, the focimeter can detect any prismatic effects present in a lens. This information is crucial for patients with eye conditions that necessitate prismatic correction, effective visual alignment, and binocular coordination.
Overall, the focimeter is a versatile tool used by eyecare professionals to accurately measure the optical properties of lenses. Its precision and reliability make it an indispensable instrument in providing correct prescriptions and ensuring optimal visual performance for individuals requiring corrective eyewear.

Etymology of FOCIMETER
The word "focimeter" is primarily derived from two components: "foci" and "meter".
1. "Foci" comes from the Latin word "focus", which means "hearth" or "fireplace". In optics, the term "focus" refers to the point where rays of light converge or from which they appear to diverge.
2. "Meter" comes from the Greek word "metron", meaning "measure". It is a suffix used to indicate an instrument for measuring or indicating something.
Combining these components, the word "focimeter" refers to an instrument used to measure or determine the focus of a lens.
