What is contrast sensitivity? Contrast sensitivity testing measures the ability to distinguish between fine increments of light vs. darkness (contrast). In situations of low light or glare, reduced contrast can affect a person's visual function such as night driving and make you feel as if you are not seeing well. Certain visual diseases (such as glaucoma or cataracts) and surgical procedures such as LASIK or PRK can lead to reduced contrast sensitivity.
Why do the Edmonton Police Service vision application and the RCMP vision application require contrast sensitivity testing?
Routine eye exams test the ability to see smaller and smaller letters on a Snellen eye chart. However, certain careers require specialized testing procedures such as the Bailey-Lovie chart. The Edmonton Police Service and the RCMP both have visual requirements that involve contrast sensitivity testing following LASIK or PRK. Ask our eye-bar optometrists for the Bailey-Lovie Low Contrast acuity chart as part of your police application.
The Bailey-Lovie Low-Contrast Acuity Test is required by Edmonton Police Services and the RCMP as part of your visual application if you have a history of LASIK or PRK.
