Eye-vitamin marketing promises everything; the evidence is narrower and more useful. Here is where nutrition genuinely earns a place in eye care — and where a supplement bottle is no substitute for an exam.
The studied formula has its place for specific stages of macular degeneration, and that decision is made from your retinal exam and imaging, not off a shelf. Our optometrists in Los Angeles tell you plainly whether you are the patient it was studied in.
Omega-3s — a conversation
Discussed in dry eye care when medically suitable, as support alongside treatment of the glands, never instead of it.
The plate — background support
Leafy greens, colorful produce and fish describe the eating pattern associated with retinal health. Eating this way is a good habit that supports eyes, but it doesn’t treat disease.
Bring your supplement list to every exam. Doses and interactions belong in your record, and we would rather trim a useless bottle than add one.
The studied formulas address progression risk in specific diagnosed stages — they were never shown to prevent AMD in healthy eyes. The exam decides whether they apply to you.
Sometimes, as support — it is a case-by-case conversation that depends on your health history, and it never replaces treating the glands.
No — carrots are fine, but myopia is managed with measured treatment, not menu changes.
Leafy greens such as kale, spinach and collard greens are a good base: they contain lutein and zeaxanthin, nutrients later added to the AREDS2 supplement for macular degeneration. Fish high in omega-3 fatty acids, such as salmon, tuna and halibut, are good for your eyes too. In NIH's AREDS studies, people who ate more leafy greens and fish tended to have a lower risk of advanced macular degeneration, and the trends suggest a Mediterranean-style diet of vegetables, whole grains, fish and olive oil does more to stave it off than the supplement alone. Eating well also lowers the risk of diabetes, which can lead to diabetic retinopathy (damage to the retina from diabetes).
Not for most people in the United States, where vitamin A deficiency is rare because most people get enough from the foods they eat. Carrots supply beta-carotene, which the body turns into vitamin A, and vitamin A is important for normal vision; the most common sign of deficiency is xerophthalmia, an inability to see in low light that can lead to blindness if it isn't treated. Eating a variety of foods covers the daily need, and more is not better: too much preformed vitamin A, usually from supplements or certain medicines, can be harmful. Bring any supplements you take to your exam so the doses can be reviewed.
