A glass of strawberry juice will not erase screen fatigue, yet it does offer something more tangible than wellness folklore. Packed with vitamin C, it feeds the same antioxidant machinery that ophthalmologists describe when they talk about oxidative stress in the eye, a process that gradually damages lipids, proteins and DNA in delicate ocular tissues.
Vitamin C acts as a water‑soluble antioxidant, donating electrons to neutralize reactive oxygen species in the tear film, cornea and retina. This reaction helps stabilize cellular membranes and supports collagen synthesis in the sclera and cornea. In biochemical terms it participates in redox cycling and can regenerate other antioxidants such as vitamin E, maintaining a broader antioxidant network rather than working as a lone hero nutrient.
That does not mean strawberry juice functions as an instant eyedrop for digital strain. Eye fatigue still depends on factors such as accommodation load, blink rate and ambient lighting. Nutrition researchers instead frame vitamin C intake as one input among many that influence cumulative oxidative damage, a bit like marginal effects in an economic model rather than a single decisive intervention. Within a diet that already includes carotenoids like lutein and zeaxanthin, vitamin C from strawberries can modestly reinforce ocular defense, but it cannot replace regular breaks, good lighting and clinical care.
