Optometrist Questions Contact Lenses

What will happen if I sleep with my contact lenses?

For last two nights I accidentally slept with my contact lenses on. I changed them in the morning. What could be its impact on my eyes?

Sleeping with your contact lenses on can cause the eye to be more susceptible to eye infections and red eyes. The lens can dry out on your eyes and adhere to the cornea which could cause a corneal abrasion if removed improperly.
Hello,

Nothing good will happen if your lenses is not designed for extended wear, be sure. If it is, there is still an increased risk of infection, abrasion, corneal ulcer, and corneal clouding, events that can lead to loss of vision. That said, modern extended wear contacts have been tested for a month of continuous wear. You balance the risk/reward,
Take care!

You can get an eye infection unless the brand of your lenses is fda approved for overnight wear.
Assuming the lenses aren’t approved for overnight wear, sleeping or over wearing your lenses can lead to oxygen deprivation, corneal swelling, or eye infections. It’s best to discontinue lens wear for a couple of days and then try again.

This can cause serious infection and ulceration of the fragile corneal surface. Please try to avoid doing this.
For most contact lens wearer who accidentally sleep in their contacts, they may suffer from red and irritated eyes, and in some extreme cases painful eyes due to an eye infection. If the eye infection is not properly treated, then visual impairment may occur. Just don't sleep in your contacts!!!
It could lead to dryness, irritation, and occasionally an infection. If you notice any redness, pain, light sensitivity, or irritation, you should follow up with your eye doctor immediately.
Sleeping in your contact lenses can have notable negative effects on your eyes. Your cornea gets starved for oxygen when you have a contact lens on your eye overnight. This can lead to corneal swelling (and subsequent loss of clarity), prescription changes and even decreased immune response. Those who over-wear their contact lenses, especially over night, are at a greater risk for corneal infections. In a worst-case scenario, this could lead to significant corneal scarring and permanent loss of vision.

Please be safe and always remember to take your contact lenses out prior to going to sleep!

Neovascularization which is development of new blood vessels on the cornea from lack of oxygen transmission to the cornea !

Also giant papillae under the lids

You can also develop corneal abrasions , ulcers
You may experience a corneal abrasion. It is a real teaching moment and an experience when remembered remind you to not do it again.
Sleeping with contact lenses increases your chances of developing eye related complications by 6 times. These include: dry eyes, eye irritation, red eye, eye infection, ulcer, corneal swelling, new blood vessel growth, etc. Sleeping in your contacts lenses is like playing russian roulette: you may get lucky but it's only a matter of time until your eyes react negatively.
Your corneas will swell and you will be 16 times more likely to get a corneal ulcer or keratitis. Your contact won't last as long and additionally, I have some old patients who wore contact lenses excessively who have suffered corneal degenerations and damage to the stem cells of the eye making the regenerative epithelium very rough and of poor optical quality.
