Eye Health & Vision Support

Reviewed by the Nimbera editorial team · Last updated May 2026

Age-related macular degeneration (AMD), dry eye disease, digital eye strain, and declining visual acuity are among the most common vision concerns. Nutritional and antioxidant interventions have been studied extensively in large randomised trials and meta-analyses, with several showing clinically meaningful benefits when used alongside regular ophthalmic care.

When to see a doctor

See an ophthalmologist or optometrist promptly if you experience sudden vision loss, flashes of light, floaters, eye pain, or any rapid change in vision. AMD, glaucoma, diabetic retinopathy, and cataracts require professional diagnosis and monitoring. Natural remedies are adjuncts to - not replacements for - prescribed treatments.

Lutein & Zeaxanthin (AREDS2 Formula)

ingestible
Chew 2022 JAMA Ophthalmology (PMID 35653117) - 10-year follow-up of 3,882 AREDS2 participants showed lutein/zeaxanthin vs no lutein/zeaxanthin reduced progression to late AMD (HR 0.91, 95% CI 0.89-0.99, p=0.03) and carried no lung cancer risk unlike beta-carotene.

Omega-3 Fatty Acids (EPA + DHA)

ingestible
Wang 2023 Journal of Clinical Medicine (PMID 38002640) - systematic review and meta-analysis of 19 RCTs (n=4,246) found omega-3 supplementation significantly improved dry eye symptoms, tear break-up time, Schirmer test scores, corneal fluorescein staining, and osmolarity vs placebo, with greatest benefit at high doses and longer durations.
$20-$55 per month depending on dose and brand; PRN Dry Eye formula runs $55-$70/month

Saffron Extract (Crocus sativus)

ingestible
Broadhead 2019 Graefes Archive for Clinical and Experimental Ophthalmology (PMID 30343354) - double-blind crossover RCT in 100 adults with mild/moderate AMD; 20 mg/day saffron for 3 months modestly improved best-corrected visual acuity and multifocal electroretinogram response density vs placebo.
$20-$40 per month for standardised 20 mg saffron extracts

Astaxanthin

ingestible
Sekikawa 2023 Journal of Clinical Biochemistry and Nutrition (PMID 36777084) - randomised double-blind placebo-controlled parallel trial in 60 healthy adults; 9 mg/day astaxanthin for 6 weeks significantly protected corrected visual acuity in the dominant eye after visual display terminal work in participants aged 40+ (p<0.05).
