To view the eye as a self-contained system is inherently myopic. A retinal hemorrhage may signal uncontrolled diabetes or a pale optic disc may hint at compressive pathology. Seemingly small findings can be the earliest indicators of underlying systemic pathologies. Therefore, preserving vision is as much about treating the eye as it is about supporting the body to which it belongs.
Patients understand this connection, and interest in natural therapies continues to grow.1 As healthcare providers, lifestyle medicine is seldom emphasized in our education and, therefore, in our discussions with patients. This lack of exposure can impede a patient’s ability to adopt healthy behaviors that prevent disease.2
With the rise in popularity of social media platforms comes the ease with which health-related misinformation can spread.3 Influencers may endorse dietary supplements while withholding risk-related information that manufacturers are legally required to provide.4 As a result, it is increasingly important that eyecare professionals be equipped to address patient questions with evidence-based information.
Overview of holistic health practices relevant to eyecare
Nutritional supplements and superfoods
Omega-3 fatty acids
Several meta-analyses have suggested that omega-3 intake enhances meibum quality and stabilizes the tear-film lipid layer, potentially decreasing evaporative loss in dry eye disease (DED).5,6-7
However, evidence remains mixed. The DREAM trial, a year-long study of more than 500 patients receiving 3,000mg of omega-3 daily, found no significant difference compared with an olive oil placebo.8
It is worth noting that participants in the olive oil placebo arm of the DREAM trial consumed a 1,000mg capsule that was roughly equivalent to 1 teaspoon of olive oil.8 Consequently, omega-3 supplementation may be useful for patients who do not heavily use olive oil.
Clinical takeaway: Omega-3 supplementation may benefit some patients, but clinicians should be transparent about the variability of responses.6,7,8
Turmeric (curcumin)
Curcumin, the active compound in turmeric, is widely touted for its broad anti-inflammatory and antioxidant properties.9 Early studies on its utility in managing diabetic retinopathy, age-related macular degeneration (AMD), uveitis, and DED show promise.10-11
However, curcumin is poorly absorbed by the body alone, so many commercial products use bioavailability enhancers, such as piperine, a component of black pepper. Piperine can slow down the metabolism of other medications, raising potential interaction concerns.12-13
High-dose turmeric may also exert anticoagulant effects and should be avoided in patients taking blood thinners or with underlying liver disease.14
Lutein/Zeaxanthin
Oxidative stress plays a central role in AMD.15 This damage is mitigated by antioxidants, both endogenous and those derived through diet.
Lutein and zeaxanthin are macular pigments that filter short-wavelength light and can counteract the harmful effects of oxidative stress. Although they cannot be synthesized endogenously, supplementation increases macular pigment optical density (MPOD), thereby improving contrast sensitivity and reducing disability glare.16-17 Both pigments can be found in leafy green vegetables.18
Saffron
Saffron supplementation has been shown to improve retinal sensitivity in a small trial of patients with early AMD.19 A follow-up study found that these improvements in macular function were sustained over 3 months, with the mean Snellen visual acuity improving by 2 lines compared to baseline values.20
Probiotics and prebiotics
The gut microbiome is a complex ecosystem of microorganisms that, when balanced, is essential for nutrient absorption, protection against pathogens, and regulation of immune function.
The concept of a gut-retina axis links dysbiosis (microbial imbalance) to inflammatory ocular conditions, including AMD and uveitis.21-23
Probiotics (live microorganisms) and prebiotics (compounds that promote microbial growth) are proposed to modulate systemic inflammation and immune regulation while improving nutrient absorption.24,25
While maintaining gut health is reasonable from a systemic perspective, direct interventional evidence for ocular disease modification remains limited.
Vitamin D
Low serum vitamin D levels are associated with increased DED severity and tear film instability.26-28 Deficiency risk is higher in individuals with limited sun exposure, darker skin pigmentation, and older age.27
Caution: Vitamin D supplementation should be monitored as excessive intake above 100 micrograms daily in adults can result in hypercalcemia and systemic complications.29

Herbal and natural topical therapies
Castor oil for dry eye
Ricinoleic acid in castor oil may stabilize the tear film lipid layer and reduce evaporation. One study found that castor oil eye drops produced symptomatic improvement and stable tear composition for up to 4 hours after instillation.30,31
It is a reasonable option for patients seeking preservative-free, plant-derived dry eye management, provided they use ophthalmic-grade formulations.31
Tea tree oil for Demodex blepharitis
Tea tree oil has been incorporated into lid hygiene products for its ability to disrupt the cell membranes of Demodex mites.32-35 These mites reside within hair and eyelash follicles. Their presence, along with inflammatory debris such as digestive enzymes and eggs, contributes to blepharitis.36
Caution: Undiluted tea tree oil can be toxic to the ocular surface.37 Patients should be warned against self-mixing concentrated products and recommended commercially prepared products.
Manuka honey
Manuka honey contains methylglyoxal (MGO), which confers broad-spectrum antimicrobial activity without the high risk of resistance often associated with antibiotics.38
Topical manuka honey preparations, such as Optimel, are already commercially available and have shown benefit for blepharitis, meibomian gland dysfunction (MGD), and DED.39,40
Lifestyle medicine and mind-body practices
Stress reduction practices
We often assess ocular conditions based on their physical presentation; however, symptoms such as pain and discomfort can vary with the patient’s tolerance and mental state.41
Emerging evidence suggests that mind-body therapies, such as yoga and meditation, may reduce perceived dry eye symptoms and lower intraocular pressure (IOP).41-43
One trial reported an average reduction in IOP of approximately 2.25mmHg over 6 weeks compared with controls.42,43 While not a replacement for conventional treatment, stress reduction can ease some of the mental burden that patients may carry with their eye condition.
Acupuncture
Small studies have reported short-term reductions in IOP following acupuncture.44,45 Another trial found improved subjective dry eye symptoms without corresponding improvements in tear film quality.46
Currently, there is little evidence to support acupuncture as a treatment option in ocular health despite its utility in managing other conditions.
Sleep habits
The relationship between sleep and ocular surface health appears bidirectional. Chronic dry eye is associated with more frequent sleep disturbances, while poor sleep quality can impair lacrimal gland function and tear production.41
Sleep disorders, like sleep apnea and insomnia, have also been linked to increased risk of glaucoma and elevated IOP.47 However, evidence suggests that these harmful effects can be reduced with greater sleep duration.48
Warm compress and lid massage
Warm compress therapy remains a popular management tool for MGD, as controlled heat facilitates meibum liquefaction and expression.49
Medical-grade devices like Blephasteam are designed to deliver consistent therapeutic temperatures and may outperform improvised home methods, which often fail to reach or maintain effective heat levels.49,50

Environmental changes and biohacking practices
Digital detox and screen habits
Unregulated screen use is associated with circadian rhythm disturbance, DED, and myopia progression in children.51
In addition to limiting screen time, the 20-20-20 rule (looking at an object 20 feet away for 20 seconds every 20 minutes) remains a simple, low-risk behavioral strategy to reduce accommodative strain.52 Encouraging complete blinking during screen use may further improve ocular surface stability.53
Infrared/red light therapy
Photobiomodulation (PBM) uses near-infrared light to activate cellular metabolic pathways, potentially enhancing mitochondrial function and reducing oxidative stress.54 Because oxidative stress is linked to AMD, PBM is gaining attention as a new treatment and has recently received FDA authorization for dry AMD.55
In one study, a proportion of patients with early-intermediate AMD showed improvements in visual acuity and drusen stabilization.54 A larger study, EUROLIGHT, is underway, collecting data from 500 to 1,000 patients across all stages of AMD.56
Cold plunging and sauna use
Sauna exposure induces vasodilation, whereas cold plunging triggers vasoconstriction.57 Contrast therapy, which combines the two, may produce a synergistic effect to improve vascular function and cardiovascular markers.58
Although more research is required on how these therapies directly affect ocular health, their systemic health benefits may, in turn, improve the ocular component of conditions such as diabetes and cardiovascular disease
Intermittent fasting
Intermittent fasting has been associated with weight loss, improved insulin sensitivity, and reduced cholesterol levels.59-62 Improved glycemic control and reduced systemic inflammation may indirectly influence the risk of diabetic and vascular retinopathies. However, ocular-specific data are minimal.
Furthermore, fasting regimens should be approached cautiously in patients with type 1 diabetes or those at risk of hypoglycemia.61

Precautions, contraindications, and red flags for wellness practices
While many holistic therapies are natural, this does not automatically mean they are safe:63
- Supplement interactions:
- Both turmeric and omega-3 can enhance anticoagulant effects. Those taking blood thinners should use caution when considering supplementation.64,65
- Excess vitamin D supplementation can induce hypercalcemia.29
- Delayed presentation: Patients may attempt to self-treat ocular symptoms with holistic approaches or trending therapies before seeking clinical advice.
- In progressive conditions such as AMD or glaucoma, delays in intervention can be sight-threatening. Patients under management should be educated on red-flag symptoms that warrant urgent medical attention.
- Non-sterile or homemade ocular products: Patients may be unaware that the same organic compound can be beneficial or toxic to ocular health, depending on formulation and concentration.
- For example, undiluted tea tree oil is toxic to the ocular surface,37 and food-grade castor oil and manuka honey are unsafe for ocular use.31,38
How clinicians should approach patient conversations around wellness practices
The goal should be to promote collaboration rather than to debunk. When a patient raises the topic of supplementation or lifestyle changes for ocular health, they should be referred to evidence-based treatments.
The following is a simple framework for discussing the impact of lifestyle medicine or changes on eye health:
- Ask: What the patient hopes to achieve. If their goal is symptom relief, disease modification, or prevention.
- Validate: The patient’s concern and interest in pursuing adjunctive treatment.
- Educate: Whether interventions have high, mixed, or speculative levels of evidence and whether they could interact with existing medication or treatments.
Many lifestyle measures, such as improving sleep and diet, are systemically beneficial and should be encouraged.
5 key takeaways
- Some holistic interventions have supportive data; others remain early-stage or speculative.
- “Natural” therapies can interact with medications and carry systemic risks.
- Ophthalmic-grade sterility matters for any topical product.
- Delayed presentation due to reliance on alternative therapy is a genuine clinical risk.
- The clinician’s role is to contextualize, not dismiss, patient interest.
