What degree of magnification is typically used for taking an external photo of both eyes?

  1. 1:1

  2. 1:2

  3. 1:4

  4. 1:8

The correct answer is: 1:4

Taking an external photo of both eyes typically requires a degree of magnification that allows for proper detail without causing distortion or excessive enlargement. A magnification of 1:4 is commonly used in this context. This level of magnification strikes a balance, providing enough detail to evaluate the external structures of the eyes while still capturing a wider field that includes both eyes in the frame. Using this level of magnification ensures that the clinician can observe the relevant anatomical features and assess them effectively during examinations or for documentation purposes. Higher magnifications might restrict the field of view too much, making it difficult to include both eyes adequately, while lower magnifications may not reveal enough detail for thorough assessment.
