Osmo Tear DS Eye Drop contains Carboxymethylcellulose 1% w/v, a viscous, water-soluble cellulose derivative used as a lubricant and tear substitute in the management of dry eye syndrome. This ophthalmic solution provides symptomatic relief from irritation, burning, and discomfort associated with dry, irritated eyes due to reduced tear production or environmental factors. Carboxymethylcellulose acts by stabilizing the tear film, enhancing ocular surface hydration, and protecting the corneal epithelium from desiccation and mechanical stress. Osmo Tear DS Eye Drop is indicated for patients experiencing mild to moderate dry eye symptoms, including those with exposure to wind, air conditioning, or prolonged screen use. The formulation is preservative-free or contains minimal preservatives to reduce the risk of ocular surface toxicity during prolonged use. It is compatible with contact lenses, although lenses should be removed prior to instillation and may be reinserted 15 minutes afterward. Dosage typically involves instilling one to two drops into the affected eye(s) as needed, up to several times daily. Patients should avoid contamination of the dropper tip and consult a healthcare professional if symptoms persist or worsen. Osmo Tear DS Eye Drop offers an effective and well-tolerated option for maintaining ocular comfort and tear film integrity in dry eye conditions.
