Hydrogel vs silicone hydrogel lenses

Silicone hydrogel and hydrogel are the two main types of materials used to make contact lenses. As there is often confusion about the two, here’s our short guide on which one could be best for you.

Soft contact lenses are all made from a mouldable plastic material. The composition of these plastics may vary, thus, creating a slightly different sensation and level of comfort depending on the wearer.

Hydrogel and silicone hydrogel lenses are both soft lenses made of plastic material. The material is absorbent and makes the lens soft when hydrated with water or solution, but hardens when dry. Silicone is the name used to describe plastic materials with a gel-like consistency that contain silicone, as well as oxygen, carbon and other elements. It’s an extremely flexible material, which makes it excellent for making not only contact lenses, but many other medical products such as implants and tubing.

Should I wear hydrogel or silicone hydrogel lenses?

It’s perfectly okay to wear either option, and most people get on with standard hydrogel lenses fine. The trick, however, is to try different options and see which one best works for you.

The main advantage that silicone hydrogel has over standard hydrogel, is that silicone hydrogel lenses are highly prosperous and absorbent. They allow up to five times more oxygen to permeate through the contact lens and reach the surface and cornea of the eye in comparison to standard hydrogel contact lenses. If oxygen cannot reach the cornea, it causes a condition referred to as hypoxia. This can lead to blurry vision, red eyes, loss of visual clarity and increase the chances of infections.

Silicone hydrogel lenses offer an increased level of comfort and hydration throughout the day when wearing lenses. For two weekly and monthly contact lenses, silicone hydrogel material helps to ensure that your lenses remain fresh and hydrated throughout their entire wearing cycle.

Silicone hydrogel lenses can be worn more comfortably for longer periods of time. This is especially helpful for those who live actively lifestyles, spend long periods of the day looking at a screen, or who are easily susceptible to dry eyes.

Which silicone hydrogel lenses should I buy?

Most contact lens manufacturers will have at least one silicone hydrogel lens in their range.  FeelGoodContacts.com stocks a wide range of silicone hydrogel lenses for short-sightedness, long-sightedness, toric lenses for astigmatism and multifocals for those who need more than one prescription in their lens and have presbyopia.

1 Day Acuvue TruEye is a fantastic daily silicone hydrogel contact lens for those who require a daily lens. The innovative lens uses Hydraclear technology and allows up to 98% of oxygen to pass through the eye, highly advantageous for those who are prone to dry eyes and irritation. Daily contact lenses wearers may also want to consider Dailies Total 1 by Alcon & Ciba Vison, which contains almost 80% water on the surface of the lens

Those who prefer to wear monthly or two weekly lenses can choose from a range of options including Air Optix Plus HydraGlyde (monthly) or Acuvue Oasys (two weekly). If you have astigmatism and require toric lenses, we highly recommend Biofinity Toric. Alternatively, if you are presbyopic, Air Optix Aqua Multifocal offer the freedom from reading glasses, while offering exceptional comfort.

Are there coloured silicone hydrogel lenses?

Yes, there are coloured silicone hydrogel contact lenses.

Air Optix Colour contact lenses are made with silicone hydrogel. Manufactured by Alcon, this vibrant collection of coloured contact lenses comes in a range of nine different colours and offer both an impressive change in style and complete visual clarity. Alcon & Ciba Vision’s exclusive 3-in-one colour technology ensures a natural, but vibrant appearance, even for those who have darker eyes. Due to the colour pigment restricting the flow of water and oxygen in and out of the eye, coloured contact lenses can sometimes be uncomfortable to wear, however Air Optix Colours silicone hydrogel surface allows water and moisture to move more freely, allowing for a slightly longer wearing time.
