ASF Stereo Fly Test

The ASF Stereo Fly Test, Model STEREO, is a widely recognized and essential tool for evaluating stereoscopic depth perception and binocular vision across all age groups. This test is instrumental in identifying visual issues such as stereopsis, amblyopia, suppression, and strabismus, which can significantly impact a patient's development and performance.

Designed for comprehensive assessment, the ASF Stereo Fly Test evaluates both gross stereopsis, typically ranging from 355 to 700 arcseconds, and fine depth perception. It incorporates a graded circle test that assesses sensitivity from 40 to 800 arcseconds, alongside an animal-themed test specifically designed for younger patients, measuring from 100 to 400 arcseconds. The test requires the use of polarized viewers to create the necessary three-dimensional effect for accurate evaluation.

Constructed from high-quality materials, the ASF Stereo Fly Test is designed for durability and to ensure sharp, long-lasting images. The test booklet features a leather-like cover, contributing to its robust design for sustained clinical use.
