Spot Vision Screener, a Versatile Digital Vision Screening Instrument

 


The spot vision screener is a hand held, portable device that helps patients from 6 months of age to adults to quickly and easily detect vision problems. Spot screens both eyes at once from a nonthreatening 3-foot distance. Touch-screen displays allow management of patient data entry, one-touch activation, and easy configuration for both auto-refraction applications and vision screening tests. The increasing prevalence of eye disorders and rising awareness among people about eye health and safety is expected to increase the demand for spot vision screeners.

Its quick speed and portability from computer-based binocular examination help clinicians to gather accurate refractive reading on patients who normally present minimal screening challenges. The spot vision screener is designed with advanced image processing technologies that provide detailed image representation of the eye's ocular structure and physiology. To accurately assess any patient, it is important to have accurate measurements of at least three critical parameters such as Ambient Refractive Error (AR), or angle, and peripheral vision. By combining these three parameters in one application, the spot vision screener can provide a comprehensive examination of a patient's eye health and visual impairments.

At least 1 billion people worldwide have a near or distance vision impairment that could have been prevented or has yet to be addressed. Uncorrected refractive errors and cataracts are the leading cause of vision impairment. Moreover, in the United States, around 12 million people (aged 40 years and more) have a vision impairment, including 8 million who have vision impairment due to uncorrected refractive error, 3 million who have vision impairment after correction, and 1 million who are blind. While, in the United Kingdom, around 2 million people living with sight loss. Of these, around 360,000 are registered as blind or partially sighted. Furthermore, near vision loss is the most common type of vision loss among Italians. In 2017, around 6,092 individuals out of 100,000 were suffering from it.
