Lubina Eye Drop contains Carboxymethylcellulose 0.5% w/v, a sterile, preservative-free ophthalmic solution designed to provide effective relief from dry, irritated eyes. Carboxymethylcellulose is a hydrophilic polymer that acts as a lubricant and artificial tear by mimicking the natural tear film, thereby enhancing ocular surface moisture and comfort. Lubina Eye Drop is indicated for the symptomatic treatment of dry eye syndrome, including cases caused by environmental factors such as wind, sun exposure, and prolonged use of digital devices, as well as contact lens-related dryness. The formulation helps to stabilize the tear film, reduce ocular surface friction, and promote healing of minor corneal epithelial damage. It is suitable for frequent use due to its non-preservative nature, minimizing the risk of preservative-induced ocular surface toxicity. Lubina Eye Drop is contraindicated in patients with known hypersensitivity to Carboxymethylcellulose or any other component of the formulation. Patients should avoid contamination of the dropper tip to prevent infection. If symptoms persist or worsen, consultation with an eye care professional is recommended. Lubina Eye Drop provides a safe and effective option for managing dry eye symptoms, improving patient comfort and visual function.
