Introduction
Brief Overview of Vision and Eye Health
Vision is an essential sense that allows us to perceive the world around us. Our eyes are complex organs composed of various parts, including the cornea, lens, retina, and optic nerve. The health of these structures is crucial for clear and accurate vision. However, factors such as age, genetics, lifestyle choices, and environmental factors can impact our vision and eye health. Common eye conditions like macular degeneration, cataracts, and dry eyes can significantly affect our quality of life. Therefore, taking proactive measures to protect and enhance vision becomes paramount.

Herbal Medicine for Specific Eye Conditions
Macular Degeneration
Macular degeneration is a progressive eye condition that affects the macula, leading to central vision loss. While herbal medicine cannot cure macular degeneration, certain herbs can help manage the condition and slow its progression.
Herbal Remedies for Managing Macular Degeneration
– Ginkgo biloba: Improves blood flow to the eyes and protects against oxidative damage
– Grape seed extract: Possesses antioxidant and anti-inflammatory properties
– Green tea: Rich in antioxidants that support eye health
