#1 Deficiency Behind POOR EYESIGHT
Feb 18, 2025
Glasses may worsen eyesight over time due to dependency. Contrast sensitivity loss affects vision in low light, often overlooked by doctors. Carotenoids like lutein and zeaxanthin play crucial roles in protecting eyes but diminish with age. Sunlight enhances retinal health and builds melatonin in eyes. Incorporating foods rich in carotenoids, such as egg yolks, and reducing seed oils can boost eye health. Omega-3s from fatty fish help reduce inflammation, benefiting both the brain and retina.

Understanding Contrast Sensitivity
The loss of contrast sensitivity, which affects the ability to distinguish shades of gray, is a significant yet often overlooked issue that impacts eyesight. Unlike standard eye tests that focus on clarity against high-contrast backgrounds, this specific sensitivity requires different testing methods that are not commonly performed. Increasing light exposure can temporarily help individuals compensate for the problem, but it does not address the root cause. Consuming antioxidants, particularly carotenoids, can protect the eyes from blue light damage and enhance contrast sensitivity through better retinal health.
