Products Information

Silicone Hydrogel Contact Lenses

Designed to be worn for longer periods and deliver a higher level of comfort, silicone hydrogel contact lenses are a contemporary alternative to standard contacts. We stock a wide range of silicone hydrogel contact lenses from big brands such as Acuvue, Proclear and MyDay.

What is Silicone Hydrogel?

Silicone is a flexible plastic that contains silicon, carbon and oxygen with a mixture of other chemicals, while hydrogel is exceptionally useful at retaining high levels of moisture and is commonly used for contact lenses. Contacts made with both of these materials create a powerful lens that can allow up to five times more oxygen to pass through to the eye and also holds on to more moisture.

Silicone hydrogel is more adaptable than standard materials for lenses, as when the lenses are dry, they are firm but quickly become flexible when they are introduced to moisture. Because of these features, lenses made from this material are typically slightly more expensive than standard lenses. However, they do provide a better feel and increased visual clarity, making them a worthwhile investment for lens wearers.

The Benefits of Silicone Hydrogel Contact Lenses

Silicone hydrogel is commonly used in premium lenses as it has a higher breathability rate. When lenses are put in place, they cover the eye which reduces the amount of oxygen that can pass through to the cornea. Over the course of wear, this can cause discomfort and in rare but extreme cases it can cause a condition known as hypoxia.

For regular lens wearers, silicone hydrogel lenses are more comfortable and help to keep the eyes healthy. In particular, for extended wear lenses, this innovative material helps to keep the wearer’s eyes safe and ensures that their eyes don’t become starved of oxygen. Keeping plenty of oxygen passing through to the eyes will help to minimise the risk of infection or irritation from occurring.

Silicone hydrogel also delivers great endurance by holding on to water more effectively. This provides more comfort to the wearer, especially for people with dry eyes, which reduces irritation and discomfort. The moisturising quality of silicone hydrogel is a great feature for monthly lenses as it helps to keep the surface of the lens fully hydrated each time the lenses are put in.

Choosing Silicone Hydrogel Lenses

Everyone’s eyes are different so choosing the right pair of lenses for your needs comes down to personal preference. However, there are some questions to ask yourself before choosing between brands to ensure you find the ideal pair of lenses for your eyes. For example, are you someone who suffers from dry eyes regularly? If so, silicone hydrogel lenses are ideal as they offer greater moisture throughout the day for longer periods than standard lenses.

Likewise, if you wear lenses for long periods of time and use computers or screens often, this material will keep your eyes healthy and comfortable. Speak to your optician if you’re unsure as they can advise you of particular brands to look out for in order to accurately correct your vision problems.

Types of Silicone Hydrogel Contact Lenses

Various vision problems can be corrected using silicone hydrogel lenses, including:

Myopia and Hyperopia – Short and long-sightedness are refractive issues which make it difficult for the individual to see things far into the distance or close up respectively. Contact lenses for these problems need to provide the wearer with excellent clarity and also remain hydrating throughout the day so they don’t become uncomfortable by the end of a long day of wear. Silicone hydrogel lenses such as the 1 Day Acuvue Trueye lenses are some of the best on the market for these visual problems, as they are incredibly comfortable and have the added bonus of providing UV protection as well.

Astigmatism – While a healthy eye is a spherical shape, people with astigmatism have an elongated eye which results in blurred and distorted vision. There are specially designed lenses for this problem, known as toric lenses, which provide a more secure fit and better comfort. PureVision2 lenses for astigmatism ensure the wearer can see clearly in all different light conditions and have high levels of breathability to keep the eyes healthy.

Presbyopia – An age-related condition, presbyopia makes it difficult for people to focus on objects at close ranges, as the muscles in the eye become inflexible. To combat this problem, multifocal lenses are used to allow the individual to see at all ranges clearly without needing glasses in addition to their lenses. Silicone hydrogel multifocal lenses such as the Biofinity lenses combine a variable prescription with excellent moisture retention and clarity for near, far and median distances.

A Choice of Wearing Patterns

In addition to being used for specific visual problems, silicone hydrogel lenses also come in a range of wearing patterns for different needs as well.

Silicone hydrogel daily lenses are the most convenient option and are well-suited to people who don’t wear lenses every day or just wear them for sport. While they are among the more expensive options, they deliver a hygienic solution to the issue of wearing lenses and remove the need for cleaning the lenses each night – after one day of wear, they can simply be thrown away and a new pair put in the next time you want to wear them.

Silicone hydrogel monthlies are better value for money than dailies and are perfect for anyone who wears lenses majority of the time. Each pair lasts up to 30 days of consecutive wear and is cleaned and stored in solution in between wears. They are slightly more hassle than dailies as a strict cleaning regime is required to remove bacteria and protein deposits building up on the surface of the lens. However, they are a cost-effective solution if you wear them on a regular basis and the use of silicone hydrogel helps to keep them comfortable right up until the end of the 30 days.

A happy medium between these two wearing patterns is two-weekly silicone hydrogel lenses. These lenses still require cleaning after each wear, but they last for two weeks instead of just one day and minimise the risk of bacteria building up as they are refreshed more regularly than monthlies.

Silicone hydrogel is well-suited to extended wear lenses too, as they provide better breathability to prevent any damage to the eyes from lack of oxygen. Extended wear lenses are contacts that you can wear consecutively, day and night, for up to a week – this means you can even sleep in them. Providing your optician approves you wearing extended wear lenses, they’re a great solution for people who don’t want the hassle of cleaning and storing their lenses in between each wear.
