Contact Lenses //

Contact Lens Consultation​
​The initial assessment for contact lenses starts with a full eye examination to ensure your eyes are healthy.  During your consultation for contact lenses we will carry out specific tests and measurements that are contact lens related. These include:

  • Keratometry, which measures the shape of the cornea

  • Diameter of the cornea

  • Distance between the lids

  • Pupil size

  • A type of microscope called a slit-lamp biomicroscope is used to examine the lids and lashes, tears and cornea (the front surface of the eye that a contact lens floats on).

At Donner Optometrists, during the Handling & Hygiene session we take the time to ensure that you know how to apply and remove your contact lenses and how to look after them.

 

All contact lens wearers need to be seen at least once a year.

Types of Contact Lenses
​Most people now opt for daily disposable soft lenses, which are the most convenient.  Alternatively, monthly or 2-weekly disposable lenses are available to almost every prescription and require just a simple rub and rinse plus an overnight soak in contact lens solution to keep them clean and hygienic.  Daily disposables require no solution at all as they are thrown away at the end of the day.  Monthly lenses cost from just £10 a month, with solutions from £3 per month. Daily disposables cost approximately £1 a pair.

Astigmatism

Most people have a certain amount of astigmatism - a slight distortion of the shape of the eye - but often not enough to affect vision.  For people with significant astigmatism, "toric" soft lenses are used to correct it. These are available in all lens types, even daily disposables.

Presbyopia

As people get older they generally need a different prescription for reading compared with distance. One simple option is just to wear reading glasses over the lenses. However, multifocal contact lenses use specialist optical technology to deliver both distance and near vision. Finally in some cases ‘monovision’ can be used: this is where one eye is focussed for distance and the other for reading.

Dry Eyes

Some people have given up wearing lenses because they became dry and uncomfortable after a while.  Newer lens materials can give longer comfortable wearing times so that your eyes can feel fresh throughout the day long into the evening, and with silicone hydrogel lenses, the optimum oxygen delivery to the eye is maintained for long wearing times.
