If you have special visual needs or are unwilling to go for daily disposables, contact lenses that can be replaced every two weeks are a good choice. These lenses are available from a host of contact lens manufacturers and are designed to suit varied needs of users. There are advantages and disadvantages of using this type of lens. Here are some things you might have to consider.
The 2 week wears are usually prescribed to those who have astigmatism and other visual defects in addition to it. This makes the contact lenses costly at the outset and manufacturing customized contacts add to the cost.
This prompts most people to go in for contacts that can be worn for an extended period and does not need replacement frequently. Extended wear is a very good option for those who like to keep their lenses on and sleep in them at night.
This is especially the case for those who are incapacitated without contact lenses. The extended wear contacts do need through cleaning to prevent an eye infection. You will also have to remove the protein debris that builds regularly on the contact lenses.
Nowadays most manufacturers have lenses for astigmatic in daily disposable schedules as well. For those who have presbyopia, an eye condition that is associated with normal aging and requires reading glasses, multifocal lenses would be an excellent option.
This has distinct advantages over the 1-2 week disposable lenses. You can use and throw them without any fear of an eye infection and you will also save up the money that would have to be spent on lens solutions and other cleansing products. The best person to advice you on this would be your eye care practitioner. You must have a thorough consultation and discuss your needs with him or her to get the contact lenses that will suit you the best.
