Quick answer

Glaucoma drops lower eye pressure to protect the optic nerve. They only work if used every day, often long term. Put one drop in the correct eye at the times prescribed. Press the inner corner of the eye for one minute after some drops to reduce absorption into the body.

## Why daily use matters

Glaucoma often has no symptoms until vision is permanently lost. Drops slow or stop further damage but cannot restore sight already lost. Skipping doses lets pressure rise again. Set phone reminders or link drops to daily routines such as brushing teeth.

## Technique tips

Good technique helps the drop stay in the eye and limits side effects.

- One drop only — a second drop mostly runs away
- After some drops, close the eye and press the tear duct at the inner corner for sixty seconds
- Wait five minutes between different drop types
- Remove soft contact lenses first if your clinic advises

## Side effects to mention

Redness and stinging are common at first. Report breathing changes, slow pulse, eyelash growth, darkening of the iris or skin around the eye, or sore, red, sticky eyes. Your team may switch drops rather than stopping without a plan.

## If you miss doses or run out

Take the next dose when due — do not double up unless advised. Order repeat prescriptions before bottles run empty. Tell your clinic if side effects or cost make daily use difficult; alternatives exist.

## Frequently asked questions

### Can I stop glaucoma drops if my vision feels fine?

No. Good vision today does not mean the optic nerve is safe. Stopping drops without medical advice risks silent vision loss.

### Why press the inner corner after drops?

It reduces how much medicine drains into the nose and bloodstream, which can lessen side effects and keep more drop in the eye.

### What if one bottle runs out before the other?

Contact your pharmacy or clinic for a repeat. Do not share drops between eyes if only one eye is treated unless instructed.

Your next step

## Take this to your appointment

Write down what has changed, when it started, your current medicines and the questions you want answered. Take these to your eye-care appointment.

Sudden loss of sight, severe eye pain or a dark curtain across vision needs immediate assessment. Do not wait to complete a worksheet.
