Considering silicone hydrogel contact lenses?
Thanks to its enhanced breathability, silicone hydrogel is quickly becoming a favoured material in the soft contact lens industry. By allowing more oxygen to flow into the eyes, these silicone hydrogel lenses prevent serious corneal disorders like hypoxia and corneal neovascularisation. Indeed, because their oxygen permeability is so strong, silicone hydrogel contacts are sometimes approved for overnight wear.
In addition to their breathability, silicone hydrogel contacts are far better at retaining water than typical soft lenses. This makes them an ideal choice for people who struggle with conditions like dry eye syndrome.
People who struggle with eye allergies or dry eyes should ask their optometrist for his/her opinion on silicone hydrogel contacts. You could also learn more about these lenses by visiting our silicone hydrogel line on this link.
Silicone hydrogel is a soft material that was first launched on the contact lenses market in the late 1990s. Today, contact lenses made from this material are the most popular choice amongst those in need of vision correction and options are available to cater for a variety of vision problems, including myopia and hypermetropia, as well as astigmatism.
What Is Silcone Hydrogel?
Hydrogel - a soft plastic that contains water - has been used in the manufacture of contacts since the 1970s and was a favourite choice due to its comfortable quality. With the addition of silicone in 1999, the lenses became more gas permeable, meaning that oxygen could pass through them and ensure better health of the cornea underneath.
Today, there are around 20 different types of formulations. The main difference being length of time they can be worn - some are only suitable for overnight wear, while others can be left in for up to 30 days.
The benefits of silicone hydrogel contact lenses
Before hydrogel was in common use, contact lenses were usually hard lenses that were not gas permeable. Next came soft contact lenses that allowed a limited amount of oxygen to get to your eyes, which limited wearing times and could cause redness.
Silicone hydrogel is a 'next generation' material - a very soft material that is extremely comfortable to wear and lets the most amount of oxygen to the eyes compared to any other contact lens material. The result - healthy eyes!
Unlike earlier types of contact lenses, most new wearers need no time to get used to them, as they can hardly be felt once inserted. The soft nature of these contacts also means that they generally stay in place better than their rigid lens predecessors.
