How do I get contact lenses ?
Contact Lens Assessment
In order to get contact lenses, first need to have a contact lens assessment test.
As the contact lens rest on the eye, it is different to a sight test. In the UK,
an appointment with a qualified contact lens fitter or optometrist is needed.
The cornea shape varies in people and so this is measured and contact lenses are
tried to check the fitting. A special instrument called a slit lamp or Burton lamp
along with an orange dye test may be used to check the health of cornea and the
fitting of contact lenses.
There are many different types of contact lenses available - and the eye care professional
will discuss the options or recommend the ones most suitable, depending on your
eye shape, occupation or needs. Click on types of contact lenses for more info.

the contact lenses yourself. The contact lens fitter may give advice on when to wear
lenses or for how long. Have to build up wearing time so that the eye can get used

whether the contact lenses are fitting properly.

return for contact lens aftercare checks.

Why do I need new spectacles when I buy contact lenses
If choosing contact lenses, it is still important to have adequate glasses to wear.
For example if an eye infection occurs, then contact lenses should not be worn as
they can make the infection worse or the soft lenses might get infected.
It may be a good idea to wear glasses at home to give your eyes a break from contact
lenses like after work, school or socialising.

wear contact lenses or wear during an eye infection.
