Effect of astaxanthin on regulating visual fatigue

Astaxanthin, lutein, and zeaxanthin belong to the same carotenoid family, but astaxanthin plays a role in the central nervous system of the eye and helps to support dynamic focus. A study on Folia Ophthalomogica Japonica pointed out that free radicals can cause inflammation related to continuous visual pressure and ciliary muscle tension, while astaxanthin supplementation can improve eye fatigue by inhibiting free radicals.

In this double-blind randomized placebo-controlled study, computer workers were given 6 mg of astaxanthin or a placebo for 4 weeks. At the end of treatment, 62% of the patients with moderate to severe eye fatigue in the astaxanthin group improved, while only 15% of the patients taking a placebo improved. The results showed that the supplementation of 6 mg of natural astaxanthin daily for four consecutive weeks can reduce eye pain, dryness, fatigue, and blurred vision, and astaxanthin can also play a role in preventing eye fatigue.

Reliable scientific evidence is effective evidence to support the benefits of astaxanthin supplementation on eye health. Only by meeting the eye nutrition needs can we better protect eye health. In addition, in terms of diet, we can eat more fresh fruits and vegetables, which is also conducive to the recovery of dry eye and visual fatigue. Eyes are sensitive and fragile. Only by properly protecting them and making them “work and rest”, can we better feel the colorful world with our eyes.
