What is the primary function of tear film?

  1. To refract light

  2. To protect against UV rays

  3. To hydrate and protect the ocular surface

  4. To detect color

The correct answer is: To hydrate and protect the ocular surface

The primary function of the tear film is to hydrate and protect the ocular surface. Tears play a crucial role in maintaining the health of the eyes by providing lubrication, washing away debris, and preventing infections. Options A, B, and D are not correct because tear film does not primarily refract light, protect against UV rays, or detect color.
