Do you know what your daily contact lenses are made of, and what typematerialused? Or why would you care?
Many people don't.
If you're like most people, just choose what your eye doctor recommends. But know this...
Different lens materials can affect eye health in different ways. The key is oxygen flow.
It's up to you: do you want more oxygen for your eyes or less?
Eye doctors typically prescribe daily disposable contact lenses that contain one of two types of soft lens materials:
- silicone hydrogel (Sil-i-kohnhahaha-tipo-jen)
It's important to know thatsilicone hydrogelhas one key advantage over hydrogel when it comes to maintaining eye health: increased oxygen supply to the eyes.
What is a "daily disposable" contact lens?
Daily disposable contact lenses (also called daily disposable lenses) are designed to be worn for one day, not including sleeping time. Wear them during the day, then take them off and throw them away at bedtime. Every day.
Two reasons why people choose daily contact lenses:
- They are the most convenient contact lens option - you can skip the daily cleaning ritual. Just throw away the lenses at the end of one day and replace them with a new pair the next day.
- Proteins and other substances naturally present in tears have less time to accumulate in the lens. Accumulation of deposits decreasesoxygen permeabilityThis may cause eye irritation and a hot or burning sensation.5The buildup of plaque can also make your eyes more susceptible to infection.6
Your eyes need plenty of oxygen to keep them comfortable, white and healthy.Unlike other parts of your body, yourscorneathey have no blood vessels to feed them with oxygen. Instead, they must receive oxygen from their tears and directly from the air to stay comfortable, white and healthy.
Therefore, it is important to know that silicone hydrogel lens material allows more oxygen to flow through the lenses to the eyes than hydrogel. In fact, the silicone hydrogel lens material allows almost as much oxygen to reach your eyes as if you weren't wearing contact lenses.1
When your eyes don't get enough oxygen,hypoxiait can happen.Common symptoms of hypoxia include:
- Eyes red and bloodshot
- corneal swelling
- Blood vessels growing into the cornea
- Blurred vision in more severe cases
If you follow the advice and recommendations of your ophthalmologist, the risk of eye damage from wearing contact lenses is very low.2
However, because hydrogel contact lenses restrict the oxygen supply to the eye, wearing them can cause excessive blood vessel formation (that red, bloodshot look of the eye) after as little as 8 hours.3
It's also important to know that your risk of hypoxia is higher if your eyes naturally need more oxygen or if you need a higher prescription to improve your vision.
For example, if you have a higher degree of nearsightedness, farsightedness or astigmatism, you may need to correct your eyesight with contact lenses that require a thicker construction. Although these types of lenses are very thin, they do not allow as much oxygen through the corneas as lower prescription lenses.
