Answer:
Dark green vegetables (Option C ) are considered the best for overall eye health according to research studies.
Step-by-step explanation:
Dark green vegetables like spinach, kale, and broccoli are rich in nutrients such as lutein and zeaxanthin, which are associated with a lower risk of age-related macular degeneration and cataracts. These antioxidants help protect the eyes from oxidative stress and damage caused by free radicals. Additionally, these vegetables contain vitamins A and C, essential for maintaining the health of the eyes and supporting overall vision.
While fish and nuts also contribute to eye health due to omega-3 fatty acids and vitamin E, respectively, dark green vegetables are specifically highlighted for their comprehensive benefits in maintaining optimal vision and preventing eye conditions.
Option C is correct.
