Purchasing ordinary eyeglasses does not have many restrictions. It goes with Personal inclinations. However, an optometrist review is mandatory before buying of contact lenses. It is the results of the review which will guide the doctor in making a decision on which type will meet your needs. Below is a discussion on factors to consider before buying Sacramento contact lenses.
There are various kinds of these lenses. The hard type is not permeable to oxygen and therefore not recommended generally. There is a soft type too. The decision on which of these two to choose will depend on comfort, health and the clarity of vision desired. Daily wear lens are acclaimed. The extended wear ones can negatively affect the eyes if not removed for prolonged periods.
People whose working hours are not well defined will be suited by prolonged wear contact lens but they should go for regular checkups. The lens are to be removed before they sleep if possible. For those using soft lenses, the disposable type though expensive is commended. They are recommended for athletes because sport activities involve rapid eye movement. Also, in case of injuries the trauma they cause to the eyes is comparatively minimal.
The contact lens are to be cleaned, rinsed and also disinfected on a daily basis. The cleansers used for different lens type differ. For the soft ones, place it on the palm, shake cleanser gently and a drop or two on the lens. Gently rub it using the middle finger until all the dirt has been eliminated. Flip it over and repeat the same on the other side. For the hard type the rubbing is by the thumb and index finger to clean both sides simultaneously. The process takes one to two minutes.
Rinsing is for removal of the cleansing product. If traces are retained, it can damage the eyes. The hard kind is rinsed with water from the tap but bottled distilled saline is used to rinse the soft contact lenses. Follow the cleaning steps in rinsing too.
Disinfection follows rinsing. Hard or the rigid lenses are disinfected by placing them in a storage solution for specially prepared for disinfection. The soft ones require heat disinfection, use of hydrogen peroxide as a disinfectant or chemical disinfection. After from implementing these tasks, the lens require protein removal every week. This is for elimination of the proteins which have accumulated from tears.

There steps to be followed are short and simple too. For the soft lens users sensitive to chemical type of disinfection, a switch to either heat or hydrogen peroxide disinfection can be made.
