Eye drops are easy to buy, but some can cause serious harm when used without supervision.
The danger of steroid drops
Steroid eye drops are very effective for some conditions, but without monitoring they can:
- Raise eye pressure and cause glaucoma, which leads to permanent vision loss
- Cause cataract
- Make certain infections, such as herpes and fungal infections, much worse
Never use steroid drops left over from a previous illness or recommended by someone else. Always use them under an eye doctor’s supervision.
Using drops correctly
- Wash your hands
- Tilt your head back and pull down the lower eyelid
- Put one drop into the pocket, without touching the tip to your eye
- Close your eye and press the inner corner for a minute
- Wait at least five minutes before another type of drop
Good habits
- Check the expiry date, and note the date you open the bottle
- Many drops should be thrown away four weeks after opening
- Never share drops
- Ask whether you should remove contact lenses before using drops
- Avoid regular use of redness-relief drops, which can cause rebound redness
