Prevent Blindness Tri-State uses a new vision screening technology, the Welch Allyn SureSight Vision Screener 14000, which allows us to screen children with less interaction needed from the children, especially those with limited verbal skills or where language barriers exist. The SureSight performs an objective refraction from a non-threatening 14 inches (35 cm) away—even through glasses and contact lenses. The unit's flashing lights and sounds engage the child throughout the screening. Abnormal results are automatically indicated by the unit, so there is no need for subjective interpretation of results. Use of the SureSight Vision Screener was validated as an appropriate screening tool in the recently completed phase II of the Vision in Preschoolers (VIP) Study sponsored by the National Eye Institute. The SureSight Vision Screener has also been approved by Prevent Blindness America for use in screening three to five year old children.
SureSight Shows Refraction
Refraction is the procedure by which focusing error is assessed. Problems with visual acuity (sharpness of vision) that result from refractive errors, such as nearsightedness, farsightedness, astigmatism, and presbyopia, are indicated by refraction. Automated refraction is performed by the SureSight Vision Screener to determine the refractive error of the eye by measuring how light is changed when it enters a person's eye. The machine uses this information to calculate the probability of refractive error. This reading is then used with the units referral criteria by age to determine is a child should be evaluated by an eyecare professional.
Features
• One-button touch starts automatic, sequential test of both eyes.
• Provides complete refractive data including sphere, cylinder, and axis.
• Operates at a non-threatening 14-inch (35 cm) distance.
• Lights and sounds engage the child's attention.
• Requires minimal child participation, making it ideal for use on young children, the disabled, and when there is a language barrier.
Prevent Blindness Tri-State is a non-profit with 501(c)(3) status.
