Everything you need to know about silicone hydrogel contact lenses
What are silicone hydrogel contact lenses?
These contact lenses are made from silicone hydrogel materials that allow more oxygen to pass through to the cornea, helping to reduce the risk of dry eyes, keratitis, and eye infections. They're more breathable than traditional lens materials, helping to keep your eyes healthier, especially during long periods of wear.
Improved oxygen supply to the corneal surface helps prevent hypoxia, a condition caused by lack of oxygen that can lead to redness, irritation or blurred vision. This makes silicone hydrogel lenses ideal for people who wear extended wear contact lenses.
Benefits of silicone hydrogel lenses
High oxygen transmissibility supports long-term eye health.
More comfortable for daily wear or occasional extended wear contact lenses use.
Less build-up of protein deposits compared to regular hydrogel lenses.
Ideal for people with dry eyes, myopia, presbyopia, or astigmatism.
Available in a range of formats, including toric contact lenses, multifocal contact lenses, and daily disposable lenses.
Who should consider them?
Silicone hydrogel contact lenses could be a great option for you, especially if you:
Lead a busy lifestyle and need all-day comfort
Wear your lenses for 12 hours or more each day
Have common vision issues like short-sightedness, age-related near vision blur (presbyopia), or astigmatism
