Calgary Eye Exams - Night Vision Bailey-Lovie Contrast Acuity Testing

The Bailey-Lovie Contrast Sensitivity Test evaluates both normal and low contrast distance vision. It ensures consistency by keeping the number of letters per row the same, with proportional spacing and a fixed size ratio, making letter size the primary variable. This structure allows for a reliable assessment of visual acuity, particularly in challenging conditions like low-light environments, such as nighttime driving, where contrast sensitivity plays a crucial role.
