To be prescribed contact lenses you need to have had a full eye test within the last 12 months. If you're new to Conlons you can bring a copy of your prescription from your old opticians. If it's over 12 months we'll include a free eye test with our optometrist before your free contact lens consultation and trial with our contact lens optician. Once we know your prescription we can give you the right contact lens advice.

Long sight (hypermetropia)
If you are long sighted (hypermetropic) the spheres in your prescription will be positive (+) and if you have little or no astigmatism then you will be ideal for the most popular daily disposable and monthly disposable lenses. You will benefit from clear all round vision at all times, and your eyes won't appear magnified as they may do at the moment with your glasses on. If your glasses are heavy and uncomfortable lenses will be ideal.
Short sight (myopia)
If the spheres in your prescription are negative (-) then you are short sighted (myopic). Because you will probably be able to see well close up, you will be perfect for lenses as you will be able to see to handle them without your glasses. Most short sighted people see better with lenses compared to glasses as well as finding them more convenient for outdoors, sports or socialising. They are also cheaper than a nice pair of glasses.
Astigmatism
If you have a cylinder and axis in your prescription then you are astigmatic. Don't worry, astigmatism simply means you are unable to focus clearly at any distance because your eye is a different shape in one direction compared to the other – a bit like the side of a rugby ball. Astigmatism usually occurs with long or short sight and is easily fixed with glasses. Low astigmatism can be masked with standard spherical contact lenses. Larger amounts are easily corrected by special toric lenses.
Presbyopia (extra help for close work)
If you have an "Add” you are presbyopic. Over the years the lens inside your eye loses flexibility so the muscles can't focus it easily. In our forties we all need extra help with the fine print over and above any distance prescription we may (or may not) wear. The answer is reading glasses or varifocals and now multifocal contact lenses have made freedom from glasses a reality for everyone, even those with astigmatism too.
