What is Lutein? How it works in the body?
Lutein is a carotenoid, meaning a natural colorant or
pigment, found in dark green leafy vegetables such as spinach, plus various
fruits and corn. Within the eye, lutein is highly concentrated in the macular region of the retina and is
dispersed in lower amounts throughout the retina and lens.Within the skin,
lutein appears to be deposited in the epidermis (outer layers) and dermis (inner layers),
providing its antioxidant and blue-light absorption functions throughout the
depth of the skin. Egg yolks are also sources of lutein. It is an important compound in the
human body, but the body does not manufacture lutein. Eating foods
containing lutein or consuming dietary supplements that contain lutein is the only way for
your body to get lutein.
What is so special about Ginkgo biloba?
Ginkgo Extract Reduces Visual Field Damage in Patients with
Glaucoma. Normal tension glaucoma (NTG) is a form of glaucoma in which the
intraocular pressure (pressure inside the eye) is normal, but there is optic nerve damage and
visual field damage (vision loss). Studies have shown that Ginkgo biloba
extract (GBE) has a favorable effect on blood circulation. The goal of this study was to
evaluate the effect of GBE on preexisting visual field damage of patients with
What is Bilberry extract?
Bilberry extract has been shown to enhance the
blood-brain barrier, which tends to become impaired with aging, showing a
decrease in vascular density, increased permeability and other abnormalities.
Also, Bilberry flavonoids appear to protect the retina
and enhance the production of rhodopsin, also called the visual purple.
Rhodopsin is a protein necessary for near vision. Exposure to light, particularly bright daylight,
high-contrast lights or even computer screens deplete rhodopsin, resulting in
poor night vision. A sufficient dose of bilberry anthocyanins apparently leads to an increase in
What are the functions of vitamins for eye health?
Vitamins help prevent, treat or cure
certain eye conditions. These are also helpful in age-related macular
degeneration (AMD), or keep the condition from
getting worse. Vitamins they protect the eye against free
radical damage. It seems reasonable to assume that strengthening of the eye
defences by increasing the intake of these vitamins would be helpful in preventing the
chronic AgingEye diseases. Recent well designed and controlled studies seem to
support this assumption. Lycopene (a different type of carotenoid found in
tomatoes) protects against prostate cancer and heart disease - therefore the
protective effect of these vitamins is not just restricted to the eye.
