Question 6

Presbyopia is known as a normal change in the elasticity of the eye due to age.

Presbyopia refers to the gradual loss of the eye's ability to focus on nearby objects, a condition that commonly occurs as people age due to changes in the elasticity of the lens.

A) Presbyopia

This option is correct as presbyopia specifically describes the age-related decline in the eye's ability to focus on close objects. It is a normal part of the aging process, resulting from the lens becoming less flexible.

B) Hypertension

Hypertension, or high blood pressure, is not directly related to changes in the elasticity of the eye. While it can affect the eyes and vision over time, it does not pertain to the normal aging change in elasticity.

C) Atherosclerosis

Atherosclerosis is a condition involving the hardening of the arteries due to plaque buildup. It does not address changes in the eye's elasticity and is unrelated to the topic of age-related vision changes.

D) Scotopic sensitivity

Scotopic sensitivity refers to the ability to see in low light conditions and is not associated with changes in the elasticity of the eye. This term does not relate to the normal aging process affecting the eye's focusing ability.

Conclusion

Presbyopia is the only option that accurately describes the normal change in the elasticity of the eye due to aging. The other options, while related to health and vision, do not directly address the specific condition of age-related loss of lens flexibility. Thus, presbyopia stands out as the correct and relevant answer.
