This lens type is replaced between every two to four weeks and is one of the most popular available. They are often the most economical option for wearers and can be found in a wide range of colours, models and specifications.
These lenses are easy to handle. They are inserted in the mornings, extracted in the evenings, and cleaned on a nightly basis. They must be placed in a dedicated receptacle filled with lens fluid overnight.
Currently, there are monthly lenses available for the vast majority of individuals suffering from sight difficulties, including those affected by astigmatism (assuming the problem is not severe). The cost of lenses is dependent upon availability in stock and the particular type of lens on order; this may vary on a daily basis.
