Visual acuity projectors are ophthalmic devices that project images onto a screen to test a person's ability to see clearly at various distances. These devices typically display symbols like letters or objects that gradually decrease in size, helping eye care professionals determine visual sharpness.
These devices are typically powered by mains electricity and are regulated according to their intended use in vision testing. They are designed to project images at standardized distances, commonly 6 meters or 20 feet, to ensure consistent and reliable visual acuity measurements.
