Winshine Tear Eye Drop contains Carboxymethylcellulose 1% w/v as its active ingredient, formulated to provide effective relief from dry, irritated eyes. Carboxymethylcellulose is a hydrophilic polymer that acts as a lubricant and artificial tear, mimicking the natural tear film to enhance ocular surface moisture and comfort. This ophthalmic solution is indicated for the symptomatic treatment of dry eye syndrome, ocular surface dryness, and irritation caused by environmental factors such as wind, dust, or prolonged screen exposure. By forming a protective, viscous layer over the corneal and conjunctival epithelium, Winshine Tear Eye Drop helps to reduce friction during blinking, prevent further epithelial damage, and promote healing. The formulation is isotonic and preservative-free, minimizing the risk of ocular irritation or hypersensitivity reactions, making it suitable for frequent use. It is recommended to instill one or two drops in the affected eye(s) as needed, typically up to four times daily, or as directed by a healthcare professional. Patients should avoid contamination of the dropper tip and discontinue use if persistent redness, pain, or visual disturbances occur. Winshine Tear Eye Drop is a safe and effective option for managing dry eye symptoms and maintaining ocular surface health.
