The Welch Allyn SureSight Screener is important for people of all ages! Vision disorders are one of the most prevalent health problems children have, and in pre-schoolers, the majority are undetected. Left untreated, these disorders often lead to amblyopia (“lazy eye”) the leading cause of monocular blindness in North Americans under 70. That's why Welch Allyn created SureSight™, the first objective, accurate vision test that ensures reliable early detection of refractive error, the primary vision disorder in children. The hand-held SureSight™ vision screener addresses the problems associated with eye chart acuity screenings-and it’s effective anywhere in the office or offsite. Since minimal patient interaction is required, SureSight™ can be used for screening infants or handicapped patients. SureSight™ can also automatically test adults. With SureSight™ you can finally screen for serious vision problems-efficiently and effectively.
