The lenses are sometimes so comfortable that many people forget to remove them before sleeping. There are also times when you may often sleep late or tired to remove your contacts. Is sleeping with your lenses really very dangerous? If so, what are the long-term risks to the eyes?
Most contact lens wearers are unaware of how sleeping with the lenses in can permanently harm them or cause infections. There are countless reasons why we get different kinds of eye infections from wearing contact lenses.
Oxygen is very vital for the cornea. It is transmitted to the eye through a very delicate blood vessel by diffusing oxygen through the tears. Lack of oxygen can cause irritation.
Wearing contact lenses daily can interfere with or even stop the flow of oxygen into the eyes. They are only worn within the allotted time. Lack of oxygen will attract different types of bacteria, fungi and even viruses which will certainly be harmful to the eyes. This can lead to corneal diseases like corneal ulcer.
You sleep with your contact lenses in?
Wearing contact lenses while sleeping is dangerous and can lead to severe dryness of the eyes. If the lenses get dry, they can be difficult to remove in the morning.
The main risk of sleeping with contact lenses in is to develop inflammation of the cornea, exactly the transparent part that covers the pupil and iris. This type of infection is mainly of bacterial origin and more rarely amoebic or fungal.
To avoid all types of infection, you should always wash your hands with soap before touching your lenses and remove them before sleeping. Try to stay away from water, which carries bacteria, and remove your lenses before showering and always clean them with specific lens cleaning products. Remember to empty the solution from your lens case after use and, in general, always use a fresh cleaning solution, as used solution loses its antibacterial power. Remember to renew your case every 2-3 months and change lenses as often as prescribed.
