What actually helps with blurry vision
Reduced visual sharpness or clarity, difficulty focusing on objects at various distances, which may be related to nutritional deficiencies or eye strain.
Vitamin A is a structural component of rhodopsin, the light-sensitive photoreceptor pigment in rod cells. It maintains corneal epithelial integrity, supports conjunctival goblet cell mucin production, and is essential for dark adaptation and visual acuity.
Dose: 2500–5000 IU
DHA comprises 60% of the polyunsaturated fatty acids in the retina. It is essential for photoreceptor membrane fluidity, retinal signaling, and neuroprotection of retinal ganglion cells. Omega-3s also support healthy tear film and reduce dry eye.
Dose: 1000–2000 mg
Zinc is essential for retinal dehydrogenase activity (converting retinol to retinal for vision), melanin synthesis in the RPE, and antioxidant protection of photoreceptors. The macula contains the highest zinc concentration of any tissue.
Dose: 15–30 mg
Accumulates in macular tissue as carotenoid, reduces eye fatigue, protects retinal cells from photooxidative damage.
Dose: 6–12 mg
Increases macular pigment density, filters high-energy blue light, provides retinal neuroprotection against oxidative damage.
Dose: 10–20 mg
Improves retinal blood flow and provides antioxidant protection to photoreceptors and retinal ganglion cells.
Dose: 120–160 mg
