Final answer:
The turning of an eye away from its normal position is known as strabismus, a condition where the eyes do not align properly. It is different from vision defects such as astigmatism or myopia, which affect the focus but not the alignment of the eyes.
Step-by-step explanation:
The term for a turning of an eye away from its normal position is strabismus, which is a condition where the eyes do not properly align with each other when looking at an object. This can cause symptoms such as double vision or difficulty with depth perception. There are various types of strabismus, and treatments may include glasses, exercises, or surgery to correct eye muscle imbalance. Vision defects like astigmatism, which involves uneven focus within the eye, and myopia, described as the eye being too long resulting in a focused image in front of the retina, are also conditions that affect vision but do not involve abnormal alignment of the eyes as in strabismus.
