Yes, saliva can be good for the eyes in certain situations, specifically as a lubricant.
How Saliva Can Help Eyes
While it might seem unusual, saliva has properties that allow it to act as a temporary lubricant for the eyes. According to a reference, "Human Saliva can be used...for lubricating eyes." This suggests that in a pinch, saliva can help alleviate dryness and discomfort.
Benefits of Saliva as an Eye Lubricant
- Temporary Relief: When experiencing dry eyes and without access to artificial tears, saliva can offer immediate, albeit temporary, relief.
- Natural Source: Saliva is a naturally occurring body fluid, readily available.
- Lubricating Properties: Its composition allows it to moisten the eye's surface.
Important Considerations
Although saliva can act as a lubricant, there are crucial factors to consider:
- Not Sterile: Saliva is not sterile and can contain bacteria that may cause eye infections.
- Short-Term Solution: It is not a replacement for artificial tears or professional medical advice.
- Potential Irritation: Saliva's composition differs from tears, and might cause irritation for some individuals.
When to Use and When Not To
| Situation | Is Saliva Suitable? |
|---|---|
| Emergency, no other options available | Yes, for temporary relief |
| Dry eyes, on a regular basis | No |
| Eye infection or injury | No |
Conclusion
Saliva can be used as a temporary eye lubricant in emergency situations where no better alternatives are available. However, due to hygiene concerns and potential for irritation, it is not a recommended regular solution for dry eyes. Always seek professional medical advice for chronic eye conditions or infections.
