The types of contact lenses available
Different Types of Contact Lenses
With the development of a range of different contact lens types, it can be hard to figure out which one is right for you. There is no concise answer as to which type is better, but there are varieties that may be better suited to your lifestyle. Following is some information that can help you decide what type to get.
The first aspect to consider is that all contact lenses can only be worn for a limited amount of time. Daily disposable contact lenses last only one day, while rigid gas permeable (or RPG) lenses last over a year. However, there is currently no contact lens type that can last forever. Another unique trait of daily disposable lenses is that they require no maintenance. As a rule of thumb, you should note that the longer you can wear the lenses, the more maintenance and care they require.
Another way to loosely categorize contacts is by seeing if they are Hard or Soft, with some contact lenses being a hybrid of the two. Soft contact lenses are much more common, are pliable, and need to be constantly hydrated. These contact lenses are more easily put in and taken out, and considered more comfortable than Hard lenses. Soft lenses are also not worn for long period of time, so there is a smaller chance that they will be infected. One of the most popular types of Soft lenses is the silicone hydrogel contact lenses.
Daily Contact Lenses
These contact lenses may only be worn once, which comes with both benefits and consequences. Since they are changed daily, you don't have to worry about disinfecting or storing them overnight. This low maintenance aspect also makes them great for people who only wear contacts for special activities, such as sports or nights out. Dailies are also considered the safest type of contact lens since there is no bacterial build up that can lead to infection or eye problems. However, they can be more expensive and you must be sure to replace them every day.
Monthly Contact Lenses
Weekly/Bi-weekly and monthly contact lenses are also often made of soft materials. These contact lenses must be removed at night, sanitized and stored in solution before use the next day. Extended wear contact lenses are a rather new product that can be worn for extended periods of time, even allowing wearers to sleep in them. This type of contact lens is made with silicone hydrogel technology. Silicone hydrogel technology allows more permeability to the eye, which lessens the chance of health risks associated with wearing contact lenses for an extended period of time.
Hard Contact Lenses
Hard contact lenses are not as common and are more often used by people with complex vision problems such as stigmatism, irregular corneas, and more. These lenses can be worn for years if cared for properly, but are harder to fit and generally less comfortable. Therefore, when choosing lenses, it's important to consider the trade-off between the comfort and convenience of soft lenses and the long lasting properties of hard lenses.
