Contrast Sensitivity and Glare for Cataract Patients

Cataract disease is a clouding of the lens which causes light scatter on the retina. This light scatter reduces image contrast and causes dimness of vision. One of the more striking problems in evaluating cataract vision loss is that many cataract patients preserve good acuity, but complain about their visual capability. The true “real-world” functional vision of cataract patients can be established as a functional acuity score using contrast sensitivity and glare testing.
