A classic and reliable tool for assessing binocular vision, the Worth 4-Dot Test uses an illuminated handheld device displaying four dots – red, two green, and one white viewed through red-green glasses. By selectively filtering what each eye sees, the test quickly identifies binocular fusion, suppression, and diplopia at both near and distance, making it an essential instrument for strabismus and amblyopia evaluation.
