Description

The 3nethra aberro is a handheld autorefractometer equipped with the Shack-Hartmann Wavefront sensor aberrometry technology to detect visual acuity and refractive errors. It is used by an eye care professional to measure a person’s wide range of refractive errors and help prescribe glasses or contact lens. Due to its portable handheld feature, it is an ideal tool for mobile eye care such as community and home eye screening. The compact refractometer can also be mounted on a chin-rest stand to achieve more stability.
