Health Information

What Does the Human Eye Do?

Human eyes collect optical information and transfer them through optic nerves.

Leading Causes of Vision Loss

Physical Factors

Degeneration of the ciliary muscles or the aging of the optic nerve or retina.

Environmental Factors

Eye strain from watching TV, playing video games, nutritional imbalance, smoking, etc.

Vision can decline when there is a deficiency in lutein, vitamin A, and beta carotene.

How to Keep the Eyes Healthy

- Maintain good posture.

- Make sure eyes get rest while reading, watching TV, and using a computer.

- Drink plenty of water.

- Consume foods such as egg yolks, fruits, and green vegetables rich in vitamin A, beta carotene, lutein, and zeaxanthin.

- Lower stress levels and stop smoking and drinking.

What is Essential for Vision Health?

- Lutein

Dietary supplements are needed because the macular pigment density decreases with age and cannot be synthesized in the body.

- Vitamin A

Needed by the retina in the active form of retinal, which combines with the opsin protein to form rhodopsin and helps with vision in dim light.

9 Steps for Healthy Eyes

- Get a vision test before age 4 for early detection of amblyopia.

- Get routine vision check-ups after age 40.

- Treat and control diabetes, high blood pressure, and hyperlipidemia.

- Consult a doctor when considering wearing contact lenses.

- Stop smoking.

- Wear sunglasses and/or hats outdoors.

- Control temperature and humidity while indoors and limit computer use.

- Keep indoors bright and do not read or watch things too close to the eyes.

- Protect the eyes when exercising or working outdoors.

What is Macular Degeneration?

Macula

Nerve tissue located in the heart of the inner retina of the eye.

- Plays an important role as a recognition point and color differentiator

of incoming optical signals.

Cause of Degeneration

- Caused by abnormal angiogenesis in the retina due to capillary disorders.

- Smoking, stress, obesity, hypertension, and high fat and calorie diets.

What is Lutein?

Lutein

-Orange carotenoid pigment

- Component of retina and macula

-Marigold flowers are a great source of lutein

Essential for Vision Health

Lutein cannot be synthesized within the human body.

Therefore, taking lutein supplements is recommended.

Pigments of macula and lutein density decline with aging.

Lutein absorbs reactive oxygen thereby protecting blood vessels and improving circulation.

Lutein supplements are recommended from the start of

aging in order to maintain macula pigment density.
