What is the term for the absence of the crystalline lens?

• A. Cataracts
• B. Aphakia
• C. Myopia
• D. Hyperopia

Answer: (B)

The term referring to the absence of the crystalline lens is "Aphakia." This condition typically arises following cataract surgery when the natural lens is removed, or it can occur due to trauma. Without the crystalline lens, the eye cannot properly focus light onto the retina, leading to significant vision problems, including a loss of clarity in images. In aphakia, patients usually experience a higher degree of refractive error, and they may need corrective lenses to help manage their vision. Understanding aphakia is essential in the study of optics, especially in contexts involving vision correction and the impact of lens removal on visual acuity.
