We know that preservatives are definitely bad for the eyes, so when we buy eye drops, we should still pay attention to buying eye drops that do not contain preservatives. However, it is best to use up preservative-free eye drops as soon as possible.

The small 0.4 ml tube of eye drops does not contain preservatives and is suitable for long-term use. But it also has disadvantages. First of all, it is expensive. A small tube of only 0.4 ml costs six or seven yuan, and one tube can only be used for a maximum of four drops. In addition, since it has no lid that can be closed again, it is directly exposed to the air after opening, so it must be dripped out within a few hours. Experts recommend that when using this eye drop, you should keep it clean and the bottle mouth free from contamination. If the sanitary conditions around you are poor and there is a lot of dust in the air, it is not suitable for use. Some patients have chronic dry eyes due to illness, lack of sleep, etc. These people need to use eye drops long-term, so they can only spend a little more money to buy this 0.4 ml "preservative-free" eye drops.

So in daily life, if possible, try to choose eye drops that do not contain preservatives. However, it should be noted that for the health of the eyes, it is still necessary to develop good work and rest habits and eye use habits to make the eyes comfortable, and naturally you will not need eye drops.
