DHA important for the eye
At the back of the eye is the retina, a thin membrane that lines the inside of the eyeball. The retina contains all our millions of photoreceptor cells, known as rods and cones, which receive and register the light that enters the eye when you look at something. The photoreceptors then convert the light into nerve impulses that are sent to the brain via the optic nerve. The rods can detect differences in brightness and help you see in dim light or darkness. The omega-3 fatty acid DHA makes up 50-70% of the fatty acids found in the outer segments of the rods in the retina. DHA helps maintain normal brain and vision function. This health benefit is achieved with a daily intake of 250 mg of DHA.
Yellow spot - indispensable for the eye and eyesight
The yellow spot is a small part of the retina that plays a very important role in our ability to see. It's what allows us to see clearly and make out details. The blue light emitted from digital screens is very energy intensive, the retina cannot stop it and it reaches the rods and cones in the eye socket where it causes oxidation. The yellow spot depends on certain nutrients to function optimally, with lutein and zeaxanthin playing a major role.
Yellow spot - rich in lutein
Lutein is a substance found in yellow and orange vegetables and leafy greens, among others. The yellow spot is very rich in lutein and links to several important properties of the eye are seen. Among other things, it has a protective effect against harmful light, while lutein protects cells against free radicals. A lack of lutein in the yellow spot is thought to affect the eye's ability to filter out harmful light and affect the eye's ability to see clearly.
