Light sensitivity—also known as photophobia—is a common and often debilitating symptom that can make bright lights, screens, or even daylight feel uncomfortable or painful. It’s frequently associated with migraines, dry eyes, eye strain, or certain neurological conditions. When severe, light sensitivity can interfere with work, daily activities, and overall quality of life.
While managing screen time, using sunglasses, and staying hydrated can help, natural supplements may offer gentle and effective support. Below are two evidence-based supplements that have been shown to support eye and neurological health, helping reduce sensitivity to light over time.
Riboflavin (Vitamin B2)
Riboflavin is a B-vitamin involved in energy metabolism and cellular function. It has been widely studied for its role in reducing the frequency and severity of migraines—a leading cause of light sensitivity. Regular use of riboflavin may help stabilize nerve function and reduce photophobia linked to neurological triggers.
- Mechanism of action: Supports mitochondrial energy production and reduces neuroinflammation
- Dosage or usage tip: Take 400 mg once daily, ideally with food to enhance absorption

Lutein and Zeaxanthin
Lutein and zeaxanthin are powerful carotenoids found in high concentrations in the retina. These antioxidants help protect the eyes from harmful blue light and UV radiation, which can trigger or worsen light sensitivity. Supplementing with these nutrients can support visual comfort and reduce glare discomfort—especially for those who spend extended time on screens or in bright environments.
- Mechanism of action: Filters high-energy light and supports retinal antioxidant defense
- Dosage or usage tip: Take 10 mg lutein and 2 mg zeaxanthin daily, often available in combined eye-health supplements

Summary
If light sensitivity is affecting your comfort and productivity, riboflavin and lutein with zeaxanthin are two evidence-based supplements worth considering. Riboflavin helps address the neurological root of photophobia, especially in migraine sufferers, while lutein and zeaxanthin provide direct support to the eyes by filtering harmful light. Always consult your healthcare provider before starting any new supplement—particularly if your symptoms are sudden or worsening.
