Carotenoids like lutein can protect our vision and enable us to see the world in its full glory. Get to know the benefits of lutein for eye health.
Unlike other carotenoids, lutein and its close companion, zeaxanthin, hold a unique distinction. They are the only carotenoids found in the human retina, specifically in the macula region, the central hub of vision. This strategic positioning highlights the significance of lutein in maintaining our ability to see the world clearly and forever, says the expert.
Lutein’s contributions to eye health extend far beyond its presence in the macula. It acts as a guardian angel for your eyes, offering a plethora of health benefits:
1. Inflammation suppression
Lutein’s antioxidant prowess helps to quell inflammation, which is a silent saboteur of eye health.
2. Free radical defense
It serves as a formidable shield against the relentless attacks of free radicals, safeguarding the delicate tissues of the eye from oxidative damage, says the expert.
3. Vision sharpness enhancement
Lutein can enhance the sharpness of vision, making it easier to discern details and enjoy the world in high definition
4. Protects against sunlight
Lutein acts as a natural sunscreen for the eyes, shielding them from the harmful effects of sunlight’s ultraviolet rays, according to the experts.
5. Light signal conversion
This remarkable nutrient plays a crucial role in converting light signals into electrical signals within the retina, enabling the transmission of visual information to the brain.
6. Safeguards against eye problems
Lutein and zeaxanthin have demonstrated promise in protecting against age-related macular degeneration (AMD), diabetic retinopathy, cataracts, and dry eye disease, safeguarding the vision from threats of these age-related ailments, says Dr Ganesh.
Lutein also offers protection against specific eye conditions:
1. Age-related macular degeneration (AMD) protection
Lutein and zeaxanthin in combination may slow the progression of AMD, a major cause of blindness.
2. Diabetic retinopathy
Lutein and zeaxanthin may reduce the levels of oxidative stress markers associated with diabetic retinopathy, a complication of diabetes that can lead to vision loss.
3. Cataract
Individuals with low lutein intake may be at a higher risk of developing cataracts, a clouding of the eye’s lens.
4. Dry eye disease
Lutein may alleviate symptoms of dry eye disease, offering respite from discomfort and temporary blurriness.
Here are some readily available Indian foods to boost your lutein intake and protect your eyes:
1. Leafy greens
Kale, spinach, broccoli, lettuce, parsley, and leeks are all excellent sources of lutein.
2. Other sources
Egg yolks, red pepper, corn, durum wheat, einkorn wheat, pumpkin, oranges, tomatoes, and pistachios also contribute significantly to lutein intake.
The importance of eyes can’t be ignored, and lutein can help to preserve its function. All you have to do is look for vegetables and fruits that are full of lutein.
