The lacrimal system is the eye’s tear production and drainage network. It keeps the surface moist, clear, and comfortable while washing away dust and germs.
How tears are made and drained
Tears are produced by the main lacrimal gland and smaller accessory glands. After washing the eye surface, they drain through tiny openings in the eyelids into the nose.
- Blinking spreads fresh tears evenly across the cornea.
- Puncta at the inner corners act like plugholes for drainage.
- Tears pass through canaliculi into the tear sac.
- From the sac, they flow down the nasolacrimal duct into the nose.
- Blockages can cause watering, infections, or sticky discharge.
Keeping the lacrimal system healthy
Small problems in this system can create big discomfort day to day. Early assessment helps avoid repeated infections or long-term watering.
- Report persistent watery eyes, pain, or swelling near the nose promptly.
- Lid hygiene and lubricating drops often improve mild symptoms.
- Simple procedures can open narrowed puncta or ducts.
- Surgery may be needed to bypass complete blockages.
- Protecting eyes from smoke, dust, and wind supports healthy tear flow.
