Custom plastics molder Mack Molding Co. has begun shipping a new wireless handheld device that can perform vision screenings in less than one second.
Mack, based in Arlington, Vt., began shipping the product, called Spot, in October. Spot was invented by PediaVision Holdings LLC of St. Mary, Fla.
Mack molds four unique plastic parts from three tools for the exterior skins that are made from UL V0-rated polycarbonate/ABS, and machines the lens holder from aluminum. Additionally, Mack manages a supply base of 35 vendors for 65 unique parts, and assembles Spot for PediaVision. After performing 14 functional tests on the unit, Mack ships the product directly to PediaVision's customers.
“I liked the notion of manufacturing at home rather than going overseas,” said PediaVision President and CEO David Melnick.
PediaVision estimates the U.S. market for automated/objective vision-screening devices at 25,000, and the global market at 100,000 units.
Although Spot can be used to assess anyone's eyesight, it is geared toward children. Spot captures results in less than one second, making it equally efficient for use in a physician's office or a large-scale public screening, such as a school, according to PediaVision.
A 5-inch touch screen displays results instantly, followed immediately by a printout that graphs where key measurements fall within an industry-defined standard. It eliminates the subjective analysis required by many vision-screening tools currently in use.
The device also screens for common potential vision issues, including nearsightedness, farsightedness, blurred vision, unequal refractive power, structural abnormalities and unequal pupil size. When the screening is completed, the resulting report indicates if all measurements are in range or if a complete eye exam is recommended.
The Centers for Disease Control and Prevention has said vision disability is the single most prevalent disabling condition among children, as about 80 percent of what children learn in their early school years is visual.
But, according to the CDC, less than 15 percent of all preschool children receive an eye exam, and fewer than 22 percent receive any type of vision screening. Of all school-age children across the U.S., 25 percent suffer from a vision problem.
