Contact Lenses

Jonathan Partridge Optometrists are an Acuvue Centre of Excellence.

A contact lens assessment and fitting service is available after an initial examination, using state of the art technology to establish your eyes health and suitability to wear contact lenses.

Contact Lens Types

There are a number of different types of contact lenses currently available, each with their own unique features. To avoid confusion we've included a brief description of the different kinds, so you're equipped with some basic background information.

When you come for your initial assessment appointment we will use the very latest corneal mapping technology to assess your needs and together we will select the most suitable lens type for you.

Hard contact lenses

These are the original contact lenses, made from a rigid Perspex material. Whilst being very durable, these contact lenses do not allow essential oxygen to pass through to the surface of the eye. Hard contact lenses have now been largely replaced by "gas permeable" lenses. Occasionally, they are still used for specialist purposes.

Rigid Gas Permeable (RGP) lenses

These lenses are made from semi-rigid materials, which allow more oxygen to pass through to the surface of the eye, making them much healthier to wear. RGPs only cover part of the cornea. As these contact lenses float on your tears there is some movement whilst blinking, it therefore takes slightly longer to get used them. However once settled they prove to be very comfortable. RGPs are suitable for most prescriptions, but more so for patients who have astigmatism, where they can give better standards of vision. RGPs are easy to handle, clean and very durable.

Soft contact lenses

Soft contact lenses are made from pliable gel-like materials, which commonly contain between 38% and 75% water, allowing oxygen to pass more freely to the eye. Your tears help maintain the softness and flexibility of the contact lens making them more comfortable to wear and adaptation is much quicker than with RGPs. Since soft contact lenses contain water, they can become contaminated, and therefore it is essential to follow the correct cleaning and disinfecting procedure.

Multifocal contact lenses

All the baby boomers are at the age where reading difficulties can be expected.

Many of these patients have been happily wear contact lenses for distance for many years and are now having to wear reading glasses over the top of their lenses to help with close work.

With the advent of the next generation of multifocal lenses existing patients can survive glasses free for most of the time.

These lenses are also great for patients experiencing reading difficulties for the first time and provide a whole new sense of freedom from glasses.

Disposable contact lenses

Traditionally, soft lenses have been replaced on an annual basis. Modern consensus is that this is unhealthy and not cost effective. Increasingly sophisticated material technology has led to the development of high quality soft contact lenses designed to be replaced more frequently and that are more and more breathable and obviously more comfortable. The combination of regular replacement and high oxygen transmission makes these contact lenses extremely healthy and comfortable to wear. Disposable contact lenses can be replaced every day, weekly, twice a month or once a month. Currently disposable contact lenses are available for the correction of all common vision correction needs including shortsightedness, longsightedness, astigmatism and the need for reading glasses.

Toric contact lenses

These are specially designed lenses to correct astigmatism. In years gone by these were difficult to measure, design and fit but this is no longer the case and we can opt for RGP, soft or disposable soft toric lenses to achieve exceptional vision.

Contact lenses for children

Many optometrists and opticians simply will not fit children with lenses. Our experience is that children manage lenses very well gaining immensely in confidence and outlook over their peers. This is especially true if they are playing sport or on stage. We do not put a lower age limit on lens wear, preferring to look at each individual child and family on a case by case basis.

Coloured lenses

You can now have tinted/coloured contact lenses, which can enhance or change the natural colour of your eyes without affecting what you see. These contact lenses, which are as comfortable as other contact lenses, are available in most prescriptions and in a variety of replacement frequencies.

Extended wear contact lenses

The latest advances in contact lens technology have led to the development of new types of disposable soft contact lens that can be worn overnight, albeit with increased risk which needs to be managed carefully. These contact lenses are made from SILICONE-HYDROGEL, some can even been worn continuously for up to 30 days.
