Introduction
Under normal circumstances, black sesame seeds may have a certain auxiliary effect in improving vision, but they cannot directly treat vision problems or significantly enhance visual acuity. This is because refractive errors such as myopia, hyperopia, and astigmatism are mainly caused by structural abnormalities of the eyeball, while other eye conditions like cataracts and glaucoma are distinct eye diseases.
Under normal circumstances, black sesame seeds have a certain auxiliary effect on improving vision, but they cannot directly treat vision problems or significantly enhance visual acuity. The detailed explanation is as follows:
Black sesame seeds are rich in vitamin A, an essential substance for maintaining eye surface health and preventing night blindness, which helps promote the normal function of retinal photoreceptor cells. Meanwhile, black sesame seeds contain certain amounts of lutein and zeaxanthin—two key nutrients found in the macular region of the retina. These components can help filter harmful blue light, reduce free radical damage to the eyes, delay eye fatigue, and slow vision deterioration. Additionally, minerals such as calcium, iron, and zinc contained in black sesame seeds can also support the metabolic processes of ocular tissues, indirectly contributing to eye health.
However, black sesame seeds cannot directly treat vision problems or significantly improve visual acuity. Refractive errors such as myopia, hyperopia, and astigmatism are mainly caused by structural abnormalities of the eyeball. Eye diseases such as cataracts and glaucoma are associated with pathological changes in ocular tissues. These issues require correction or treatment through medical interventions. Black sesame seeds cannot alter the structure of the eyeball or reverse ocular pathology; their role is limited to providing nutritional support to the eyes and assisting in maintaining normal ocular function.
