Dryer at night, why?

[lollipop]

Hi

Why is it that eyes become dryer at night? This has always puzzled me as there is less blinking going on so you would think the eyes would be less red.

Can anybody advise please?

I have the same problem while sleeping. Is this what you mean? Or do you just mean at night in general.

If it is while sleeping I have lagopthalmos (my eyelids do not stay shut while I am sleeping) therefore the tear film can evaporate during the night and cause worse dry eyes than during the day.

The body naturally reduces tear production at night. When eyes are dry to begin with, this makes for an uncomfortable night and morning.

Becuase your dry eyes are caused by an allergic reaction to the dust mites that live in your mattress, pillow, and bedding.

If my eyes are closed even for an hour it takes a very long time to rewet. Also I have heard things like watching tv you blink less. Possibly just from strain from the day. First thing in the morning is hard and night

GinaJ--

Me, too. Even if I take a nap, I have to put gel in my eyes--they just go bone dry as soon as I fall asleep.

I'd say the evenings are worse if you have heating on. I also find electric lights make my eyes worse.

Did you post this? Only I suffer from dust mites and am now wondering if they are causing my eye problems. (My house has no rooms without carpets which I am sure the mites love.)

Hey! I learned something!

I just learned something! In a 2007 article in Review of Optometry that discusses Recurrent Corneal Erosions, I discovered that both dry eyes at night while sleeping and upon waking in the morning with drier eyes can be explained thusly:

"A small degree of corneal edema is typical in about 4% of the normal population.1 This can be explained largely by two physiological events. First, the active transport pump mechanism of the endothelium slows during sleep, reducing its impact on maintaining corneal deturgescence.

Second, eye closure during sleep retards evaporation of the pre-ocular tear film; this can exacerbate the problem. This effectively decreases tear film osmolarity, diminishing the osmotic effect on the semi-permeable epithelium."

I think that the above in red is why Dwelle helps so many of us to get through the night.

Liz,

That was very interesting. I started sticking this summer on the area where I have the scar from the cyst aspiration. I can't wait to get this dwelle and see how it works for me.

Thanks for posting,

What does "pre-ocular tear film" mean?
