Questions: Proper execution of the Titmus stereopsis test requires the patient to wear what type of spectacles? bifocal spectacles red/green spectacles spectacles with prisms light-polarizing spectacles

The answer is the fourth one: light-polarizing spectacles.

Explanation for each option:

• Bifocal spectacles: These are used to correct vision at different distances, typically for people with presbyopia, and are not used for the Titmus stereopsis test.

• Red/green spectacles: These are typically used for tests involving color vision or certain types of 3D vision tests, but not for the Titmus stereopsis test.

• Spectacles with prisms: These are used to correct certain types of vision problems, such as double vision, but are not used for the Titmus stereopsis test.

• Light-polarizing spectacles: These are the correct type of spectacles required for the Titmus stereopsis test. The test uses polarized images to assess depth perception, and the patient needs to wear polarizing spectacles to properly view these images.

In summary, the proper execution of the Titmus stereopsis test requires the patient to wear light-polarizing spectacles.
