maybe good idea for avoiding redeye at the swimming pool too. |
|
|
The fluid on the surface of a mammalian eye is complex and consists of several layers. There is a risk that even normal saline, in contact for an extended time, might cause disturbance to the system and result in serious problems. |
|
|
With the eyelids closed, this might not be so much of an issue. |
|
|
When the eyelids are open, the cornea relies on oxygen permeation to keep it alive, hence the development of gas-permeable contact lenses. If the saline became deoxygenated, this might have negative consequences. |

We are not saying that this is a bad idea; just that they eye is a complex and delicate structure ioerating in a carefully controlled ecosystem all of its own, and great care is needed to avoid damage. |
