I’ve heard that contact lenses won’t allow my eyes to breathe – is this true or is it a myth?
For healthy eyes a certain amount of oxygen needs to reach the cornea and therefore has to pass through your contact lenses. The amount needed differs if you wear your contact lenses just throughout the day or if you want to sleep in your contacts. Your optometrist will recommend the most appropriate contact lens, which suits your needs and your lifestyle. If you follow the recommendation of your optometrist, you can be confident that your eyes will not lack oxygen to breathe. However, although the contact lens material itself is critical for the sufficient supply of oxygen to the cornea, oxygen supply depends on more factors. For example lens care is a very important criteria. Any deposit on the surface of the contact lens will block off oxygen going through the lens. That’s why cleaning and dis-infection is so important for eye health. Combined with short replacement cycles proper contact lens care will let you enjoy your lenses to its full potential.
