Your eyes do not live in isolation. They are wired into your brain, your nervous system, your sleep, and your daily habits and that means “better vision” often starts with choices that look nothing like an eye chart. We walk through the food and lifestyle routines Dr. Mark Grossman follows personally as an integrative medical optometrist and acupuncturist with decades of experience in natural eye care. We get specific about diet for eye health and brain health, including why absorption matte...
Astaxanthin is showing up everywhere, from eye health supplements to skin and brain formulas, but most people still can’t answer the basics: what is it, where does it come from, and what does the research actually suggest it can do. We walk through why seniors are at higher risk for macular degeneration, glaucoma, cataracts, and dry eye, then connect those real-world concerns to the bigger drivers behind aging and vision loss: oxidative stress and inflammation. We explain astaxanthin as a ma...
Your eyes are not separate from your brain. Indeed, they are part of the same system. That is why we take nutrition seriously when we talk about protecting vision as you age, especially if you are worried about macular degeneration, glaucoma, cataracts, dry eye, or the slow creep of cognitive decline. We dig into the MIND diet, a research-backed blend of the Mediterranean diet and the DASH diet for blood pressure, and explain why it is so compelling for both brain health and eye health. I br...
We connect the dots between brain health and vision, showing how diet, the gut–brain axis, and key nutrients protect memory and eyesight. We share evidence on Mediterranean and MIND diets, spotlight DHA, B vitamins, curcumin, and offer practical food swaps that lower inflammation. • eyes as brain tissue and early detection via retinal scans • diet’s role in synaptic plasticity and cognition • gut–brain axis signals shaping mood and memory • Mediterranean, green Mediterranean, and MIND diet i...
We explain why vitamin D3 matters for eye health, where research points across dry eye, glaucoma, macular degeneration, diabetic retinopathy, and cataracts, and how to make smart, test-guided choices. We share target intake ranges, personal practices, and a simple plan: don’t guess, test. • vitamin D3 as a hormone shaping inflammation, immunity and oxidative stress • widespread deficiency due to limited sun, diet and indoor life • target serum 25(OH)D levels and common intake ranges for seni...
We explore why cataracts form, what your lens needs to stay clear, and how diet, supplements, and habits can reduce risk and improve outcomes before and after cataract surgery. We also cover dry eye prevention around cataract procedures and how to protect the retina from increased light exposure. • reasons cataracts develop and timing across ages • nutrients that support glutathione and lens proteins • role of carotenoids in filtering blue and UV light • evidence on fruit and vegetable intak...
Dry, gritty, or burning eyes don’t have to be your “new normal.” We take a deep, practical look at hyaluronic acid—what it is, why your eyes love it, and how to use it—to bring real-world relief for dryness, irritation, and even contact lens discomfort. Drawing on decades of integrative eye care, we lay out clear steps for choosing the right eye drop strength, pairing topical relief with smart supplementation, and building meals that support your tear film and the vitreous. We break down the...
Dr. Grossman explores why he believes that glutathione is the eye’s master antioxidant. He discusses how to restore it with food and supplements to protect against cataracts, glaucoma, and macular degeneration. He shares practical tips, synergies with vitamin C, and whole‑body benefits that support lasting vision. • glutathione’s role in lens, retina and cornea protection • how aging, UV and toxins lower glutathione • sulfur‑rich foods and crucifers that rebuild levels • NAC, alpha lipoic ac...
