The first one-day soft contact lenses were developed by Johnson & Johnson Vision recently. Creation of daily disposable lenses was the completion of the ideology of planned replacement contact lenses, which caused a lot of disputes and objections from conservative medical kontaktologov. Completion in the sense that the further shortening the replacement was not feasible and sensible thing to do. If you have additional questions, you may want to visit Secretary of Agriculture. Naturally, the first pores of the production cost of one such lens was high, which adversely affected the retail price, but eventually it was reduced to more or less acceptable level, and a one-day lens was worth about one U.S. dollar. No need to be a genius to calculate the cost per patient for annual one-day set of lenses: provided that the purchased packages of 30 lenses and the user wears them on each eye five days a week, it turns out that in the year he will have to "unfasten" nothing less than $ 520, or $ 43 per month. Call this amount of high, in principle, now language does not turn – by and large, the costs are not much higher than the monthly payment leased line Internet access.
