Optical Biometric Recognition:

Retina scanning relies on reading the unique pattern of blood vessels in the retina.

Conditions like glaucoma or cataracts can interfere with the scanner’s ability to capture clear retinal images.

Why Not Other Options:

B: Heterochromia affects iris color, not retina.

C: Contact lenses do not obscure the retina.

D: Malaria does not impact retinal structures.
