Answer:

Prolonged computer use demands continuous eye adjustment, often leading to dryness, fatigue, glare, or blurred vision by the end of the day. Many individuals develop a habit of using daily eye drops to rinse their eyes and relieve fatigue, even without a clear medical condition. However, eye drops should always be used according to a specialist's instructions.

Extended exposure to blue light risks retinal damage, accelerates macular degeneration, causes dry eyes, corneal inflammation, and increases the risk of myopia. Blue light can also induce oxidative stress, disrupting DHA structures and impairing photoreceptor function. The eyes must constantly adjust, leading to dryness, fatigue, and reduced visual clarity. These damages occur in deep eye structures, while eye drops only act on the ocular surface, thus not addressing the root cause of vision impairment.

For soothing eyes after computer work or rinsing away dust, a 0.9% sodium chloride solution (physiological saline) is a relatively safe choice. This solution offers temporary comfort but is not an eye supplement; it does not improve vision or protect the retina or macula.

To ensure long-term vision protection, individuals who work extensively with computers should take regular eye breaks, adjust their workspace lighting appropriately, limit continuous close-up viewing, and nourish their eyes internally with a balanced diet. Nutrients such as lutein, zeaxanthin, omega-3, and B vitamins help protect optic nerve cells and support better eye adjustment.

You can supplement with natural nutrients like broccophane (extracted from broccoli) to boost thioredoxin (antioxidant proteins) and protect retinal pigment epithelial cells and the lens. This essence helps reduce dry and tired eyes, supporting the prevention and slowing the progression of refractive errors such as myopia, hyperopia, and astigmatism. If you experience persistent symptoms like pain, irritation, blurred vision, or prolonged vision loss, you should consult an eye specialist for appropriate advice and treatment.
