Lutein: Unveiling the Secret to Vision Protection!

Hello. This is Gangnam Smile Eye Clinic, helping you rediscover the happy smile that comes from the joy of seeing!

You're all familiar with lutein, widely known for its benefits to eye health, aren't you?

But do you know exactly what aspects of lutein are good for your eyes?

Lutein is a pigment found in the macula lutea, which is crucial for vision, and it is also an essential nutrient for the entire body, including the brain, skin, and heart.

Just because lutein is abundant in the eyes doesn't necessarily mean it's good for them.

Lutein is important because it is essential for maintaining the function of the macula, where photoreceptor cells are densely packed. Let's explore how it helps macular function.

Lutein is an essential nutrient for the entire body, including the brain, skin, and heart, not just the eyes (macula).
1. Antioxidant Action

Antioxidation means reducing harmful reactive oxygen species in the body.

Oxygen is essential for humans, so why should we reduce reactive oxygen species?

It's because reactive oxygen species attack normal cells, causing aging and disease.

Lutein prevents eye aging through its rich antioxidant action.

2. Blue Light Blocking

UV rays are harmful to the eyes and cause various diseases (such as cataracts and macular degeneration).

Blue light (blue visible light), which is close to UV rays, is also thought to have a negative impact on the eyes.

Lutein acts as a filter in the eye, blocking UV rays and blue light, which is why it's sometimes called ‘sunglasses in the eye’.

3. An Essential Nutrient That Must Be Supplemented

Lutein is an essential nutrient for various tissues, including the macula, but it cannot be synthesized by the body itself, so it must be supplemented through food or nutritional supplements.

It is difficult to consume the recommended amount (6-20mg) solely from lutein-rich foods (green leafy vegetables and egg yolks).
