  • - Some contact lens brands say

  • that it's okay to sleep in them,

  • but as a general rule, it's really not.

  • My name is Dr. Irina Belinsky.

  • I am an eye surgeon specializing

  • in oculoplastics and ocular oncology.

  • Contact lenses are safe,

  • but they're safe if you take care of them appropriately,

  • and part of good contact lens hygiene

  • is not sleeping in your contact lenses.

  • Think of the contact lens as foreign material in your eye.

  • It's sort of like a sponge,

  • and to be comfortable,

  • the contact lens needs to be moist,

  • so, it absorbs moisture from your eye,

  • and it can also trap bacteria,

  • and so, it's very important

  • to take your contact lenses out

  • to clean them periodically.

  • Leaving them in when you sleep can cause an eye infection

  • that can sometimes be really, really bad.

  • A lot of the infections can be mild

  • and go away with antibiotic eye drops,

  • but some infections can be really, really severe,

  • and even if they go away,

  • they can cause scarring

  • of the surface of your eye,

  • which is the cornea,

  • and that scar can cause

  • sort of a permanent change in your vision.

  • Sometimes an infection can be devastating,

  • and it can completely cause the eye

  • to scar to the point that someone might need

  • a corneal transplant or lose vision completely.

  • Really serious blinding kind of infections

  • related to contact lens wear are rare, fortunately.

  • If they were common,

  • then nobody would ever wear contact lenses.

  • So, they are exceedingly rare,

  • and they usually have to do with really,

  • really bad contact lens hygiene.

  • So, good contact lens hygiene has to do with a few things.

  • One, knowing if your contact lens needs

  • to be changed every month or every two weeks

  • and trying to stick to that,

  • even if you have to put a little reminder

  • in your calendar.

  • The more common thing that we see

  • is just contact lens overwear.

  • The cornea gets devoid of oxygen.

  • So, a contact lens does start to break down over time

  • so it doesn't have a smooth surface.

  • It's gonna form micro-breakdown kind of edges,

  • and the contact lens will also dry out.

  • I mean, your eye just doesn't have enough moisture

  • to keep a contact lens in there forever.

  • If you think of the contact lens as a sponge,

  • like the sponge in your kitchen,

  • you have to clean it every so often,

  • and you might even have to replace it every so often,

  • because it just doesn't do the job right anymore.

  • A contact lens can become kind of folded

  • and entrapped in the eye underneath the lid,

  • so, I have seen that

  • where patients come in with chronic red eye,

  • and you look around very carefully

  • and sometimes, and this is also rare,

  • but you can actually extract a contact lens

  • that has probably been there for months.

  • It can happen if you put it in wrong.

  • It can happen if you sleep in it.

  • It can happen if you don't take it out,

  • or if you forget to take it out.

  • Take your contact lenses out.

  • Don't leave them in.

  • Take them out every day.
