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.
