Question

What is the purpose of glare test or brightness acuity testing (B.A.T.)?

1) To test the visual acuity of an individual
2) To measure the brightness sensitivity of an individual
3) To evaluate the impact of glare on visual performance
4) All of the above

Answer 1

The glare test or brightness acuity testing (B.A.T.) evaluates the impact of glare on visual performance, differing from the Snellen chart which assesses overall visual acuity without bright light interference.

Step-by-step explanation:

The purpose of glare test or brightness acuity testing (B.A.T.) is to evaluate the impact of glare on visual performance. This type of test is important in determining how well an individual can see in the presence of bright light, which can be a common issue for many, especially those with certain ocular conditions. While the Snellen chart is used to assess visual acuity by having individuals read letters at a distance, the B.A.T. specifically measures how glare affects one's ability to see clearly.
