How lensometers work
Lensometers are a quick and convenient way to measure the eye that results in a clean and accurate reading. While ophthalmologists have several tools at their disposal, lensometers are convenient because they can help determine the strength of a patient’s eyeglass or contact lens prescription. That way, it reduces the chance of operator error and uses advanced algorithms to calculate and measure prescription strength. This is one of the only machines that can help correct or modify a prescription after the patient has already been prescribed with glasses or contact lenses.
Lensometers are particularly useful when a new patient with existing glasses comes to visit the ophthalmologist, with no record of their previous prescription. Instead of having to re-do another eye exam, the doctor can use a lensometer to take accurate readings of the lenses and determine what strength needs to be prescribed.
Lensometers are also known as lensmeters or sometimes focimeters, and are used by most doctors in the eye medical industry. When it comes down to it, lensometers are the most accurate devices used by ophthalmologists in order to take accurate measurements of the strength of a patient’s current pair of glasses or contact lenses. Whether manual or automatic, there are plenty of lensometers that can suit the needs of any optical office. They use telescopic technology to figure out what kind of strength is held in the lenses.
