I happen to be blind as a bat: - 4 myopic to be exact. After fifteen years of wearing monthly contacts (and buying litres of disinfecting solution) I finally took a leap of faith towards daily contact lenses and I have not regretted it.
Dailies - disposable contact lenses - are not only very convenient for travelling but they are also more hygienic (no danger of protein deposits) and are generally a "healthier" option. I work in an office and my eyes are sensitive to air-conditioning, what sometimes used to result in conjuctivitis.
For years I was put off by their price, but now I am happy to report that a pair of contacts costs 1 EUR/day. I order at: http://www.lensonline.be/, 90 contact lenses cost 45,50 EUR with delivery (Cibavision).
