Something to point out - Some people find contact lenses really easy to get stated with, and some don't. When I first tried them years ago it took several visits to the optician to practise. That in mind, if you are a bit anxious about it and think you might struggle, it would be worth going to an independent optician, ideally one who charges for the consultation, as they ought to then take your time with you. Many of the chains will do a free contact lens consultation, but as you are not paying for this time they can try and rush you out.
The contact lens manufacturers do free trial packs so there's no need to worry about the cost of your first pack of lenses.
