Meta-analysis of RCTs supports carotenoids for AMD
Why it may be relevant
Lutein and zeaxanthin are the macula's own pigments, and supplementing them is among the best-studied ways to support long-term central vision if you are concerned about age-related macular degeneration (AMD).
A systematic review and network meta-analysis of randomised trials found carotenoid supplementation reduced the risk of progressing to late AMD and supported visual acuity; the benefit is clearest for people who already have AMD and is not a guarantee against future eye disease.
Dose or use 10–20 mg lutein and 2 mg zeaxanthin daily with a fat-containing meal.
Key study Systematic review and network meta-analysis (2022, PMID 34995151): Efficacy of different nutrients in age-related macular degeneration: A systematic review and network meta-analysis.
EvidenceSupported by controlled trialsTime to resultsTypically 8–16 weeks
Caution: Smokers should avoid high-dose beta-carotene combinations; consult a doctor.
If you want to protect long-term central vision, saffron has been tested directly in people with early age-related macular degeneration (AMD), the main threat to the macula.
A randomised, placebo-controlled crossover trial found oral saffron modestly improved retinal function and visual acuity in mild-to-moderate AMD; the effects were small and it is not a substitute for standard eye care or monitoring.
Dose or use 20 mg standardised saffron extract daily with food, the dose used in clinical studies; consult your eye doctor first if you already have AMD.

A systematic review and meta-analysis examined omega-3s as a possible preventive strategy for age-related macular degeneration, which fits a long-term vision-support goal, though findings across studies are mixed.
Some studies suggest EPA/DHA may support retinal health and healthy inflammation balance, but large clinical trials have shown mixed results for eye-specific benefits.
Dose or use 1,000–2,000 mg combined EPA/DHA daily with food.

RCT review suggests possible dry eye symptom relief
Why it may be relevant
A systematic review and meta-analysis of RCTs found auricular acupressure specifically beneficial for dry eye disease.
Some clinical research suggests that pressure on ear points may ease dry eye discomfort non-invasively, though the underlying trials are small and results are preliminary.
Dose or use Press firmly 2–3 min on auricular (ear) eye-reflex points, both sides, 1–2x daily.

Caution: Avoid broken or irritated skin on the ear.
An RCT tested laughter exercise directly against standard eye drops for ocular surface discomfort, making it uniquely relevant to dry eye relief.
Supported by clinical research suggesting laughter exercises may ease dry eye discomfort, possibly through increased tear production and stress reduction.
Dose or use Practise structured laughter exercises (deep, sustained 'ha-ha' laughter in short sets) for a few minutes several times a day, as used in the trial; no equipment needed.
Key study RCT (2024, PMID 39260878): Effect of laughter exercise versus 0.1% sodium hyaluronic acid on ocular surface discomfort in dry eye disease: non-inferiority randomised controlled trial.
EvidenceSupported by smaller clinical studiesTime to resultsTypically 2–4 weeks
Caution: Check with your healthcare provider before starting, especially if you are pregnant or breastfeeding, take prescription medication, or manage a chronic condition.
An evidence map of randomised trials included warm moxibustion among the therapies studied for dry eye disease, so it may be worth exploring if your eyes feel dry and gritty.
Has been studied for dry eye as part of acupuncture-and-moxibustion research; a clear benefit to tear function has not yet been established.
Dose or use Have warm moxibustion applied by a trained acupuncture-and-moxibustion practitioner, and ask them how many sessions and how often suit you. Never apply heat near the eyes yourself.

Caution: Must be performed by a trained practitioner; avoid near the eyes without professional supervision.
A double-masked randomised trial tested a probiotic for the gut-eye axis in people with dry eye disease, so it may help if your dryness comes with inflammation.
Supported by a controlled trial suggesting that modulating gut bacteria may help reduce dry eye inflammation; the exact strain that works best is not established.
Dose or use Follow product labeling; consult a healthcare practitioner.

Traditionally used for eye comfort
Why it may be relevant
If your eyes feel dry and irritated, acupuncture is a traditional therapy some people turn to for eye comfort and to ease tension around the eyes.
Used in traditional practice for eye-related complaints; a specific benefit for dry eye disease has not been confirmed in controlled clinical trials.
Dose or use Work with a qualified, licensed practitioner; ask them how many sessions and how often are right for you.

If tired, strained eyes from screens are your main issue, astaxanthin is a carotenoid antioxidant that concentrates in eye tissue and has been tested specifically for digital eye strain.
A randomised, double-blind, placebo-controlled trial found daily astaxanthin reduced computer-vision-syndrome symptoms and visual fatigue; that trial was in screen-heavy children, so results in adults may differ.
Dose or use 4-12 mg daily with a fat-containing meal.

If screens leave your eyes tired and strained, bilberry extract has been tested in adults doing computer (VDT) work, where the eye's focusing muscle tends to fatigue.
A randomised, placebo-controlled trial found 12 weeks of standardised bilberry extract improved an objective measure of the focusing muscle's recovery after screen work; this reflects focusing function rather than proven relief of how your eyes feel.
Dose or use 120–240 mg of standardised extract (25% anthocyanins) daily.

Neck point for eye strain and tension
Why it may be relevant
If screens leave you with tired eyes and tension headaches, GB20 sits at the base of the skull, right where that tension tends to collect.
Traditionally used to relieve tension and improve circulation to the eyes; the library notes it may reduce eye fatigue and vision strain, especially from digital use.
Dose or use Press the hollows on either side of the neck, just below the base of the skull, for 1-2 minutes with steady pressure; repeat as needed.

Omega-3 Fatty Acid Deficiency (EPA & DHA)
Evidence grade not assigned · Traditional use long-standing
Low omega-3 linked to dry eyes
Why it may be relevant
If dryness and irritation are your main issue, low EPA/DHA is a testable root cause; omega-3s help keep the ocular surface lubricated and calm.
EPA/DHA insufficiency is tied to dry, inflamed surfaces and dry skin, so restoring healthy levels can support tear quality.
Dose or use Consider an omega-3 index test, and increase oily fish or an EPA/DHA supplement to correct any shortfall.

Vitamin A Deficiency
Evidence grade not assigned · Traditional use long-standing
Classic deficiency behind dry eyes
Why it may be relevant
If your eyes feel dry and gritty, low vitamin A is a genuine root cause worth ruling out; dry eyes and night blindness are its hallmark signs.
Vitamin A is essential for the tear film and eye surface, so correcting a true deficiency can relieve dryness; a severe lack can progress to xerophthalmia.
Dose or use Ask your doctor to check your vitamin A status before supplementing, and treat any deficiency under guidance.
Key study Vitamin A deficiency is a recognised cause of dry eyes and night blindness; consider testing to see whether it applies to you.
