Eye Health: Most Effective Dietary Supplements

Eye health can be defined as a condition where all structures of the eye, including the cornea, lens, retina, optic nerve, and eye muscles, function in a coordinated manner to provide clear and comfortable vision. It also involves the absence of pathologies or abnormalities affecting these structures. Good eye health is based on several parameters: 2 Quality of vision: The ability to perceive objects clearly (visual acuity), without blurriness or distortion, under various lighting conditions. • Integrity of eye structures: The absence of lesions, inflammations, or abnormalities in the outer layers (cornea and sclera) or internal layers (retina, macula, lens). • Normal intraocular pressure: A balance of fluids inside the eye, preventing risks of glaucoma. • Adequate ocular blood circulation: Ensuring the delivery of the necessary nutrients and oxygen to maintain retinal function. • Visual comfort: The absence of pain, irritation, dryness, or eye fatigue, even after prolonged visual efforts. • Functional capabilities: Binocular coordination (eye alignment), normal pupillary response, and accommodation abilities allowing clear vision at different distances. • Color and contrast perception: The ability to distinguish shades and details, essential for functional vision in daily life.

Eye Diseases and Risks

Eye diseases and risks associated with eye health are numerous and can severely impair vision if not detected and managed in time. Among the most common pathologies are cataracts, a progressive clouding of the lens leading to blurred vision and increased light sensitivity. Glaucoma, characterized by increased intraocular pressure, can damage the optic nerve and cause irreversible peripheral vision loss. Age-related macular degeneration (AMD) affects the central retina, reducing the ability to see fine details, while diabetic retinopathy, caused by damage to retinal vessels, is a common complication of diabetes. Dry eye syndrome, often associated with excessive screen use, causes chronic irritations and discomfort. Among risk factors, age, smoking, excessive UV exposure, hypertension, and systemic diseases like diabetes are leading causes.
