Two Types of Contacts

Posted by Turtle Contacts on

Contact lenses are made using different types of plastic, but in general, there are two types of contacts: soft and hard contact lenses.

The Soft Contact Lenses

Soft contact lenses are gel-like, thin lenses conform to fit the shape of the eyes. These types of contact lenses tend to more flexible than hard, rigid gas permeable contact lenses which also makes them more comfortable and easier to get used to. Some type of soft contacts are as follows:

Daily wear contact lenses - These lenses are the most popular among contacts user. They are the ones you put on in the morning and remove before going to bed. They should be slept in and when taken care of the proper way, they last for six months up to one year.

Disposable contact lenses -  They are contact lenses designed for short-term use. Depending on their composition, disposable lenses may need to be replaced every day and be thrown away after use. Make sure not to re-use your contact lenses when you know that they are disposable.

Extended wear contact lenses - These type of contacts are designed to let enough oxygen in our cornea even when we are sleeping. They can be used for 7 straight days. Some super permeable contact lenses can be worn for up to 30 days, these lenses though maybe a little bit less comfortable than the 7 days extended contacts ones.

The Gas Permeable Contact Lenses

Gas permeable contacts are generally made of harder plastic materials and do not contain any water. While they are not as flexible and comfortable as the soft contact lenses, rigid gas permeable lenses allow more oxygen to pass through our eyes reducing discomfort and risk of eye irritation.

Rigid gas permeable contact lenses are the type of contacts which are used to create contacts lenses that can correct vision problems such as astigmatism. After some time, people wearing hard contacts can also adopt and be comfortable around them. These contracts tend to be more durable than the soft contact lenses as well, they are not easily damaged or scratched. Rigid contacts do not require frequent replacement and can be used for two to three years.

Type of Contact Lenses

Advantages

Disadvantages

Soft

  • Flexible and more comfortable
  • Extended wear and disposable options available
  • Shorter adjustment period
  • Able to stay in place better, even with vigorous physical activity
  • Less durable
  • Require more frequent replacement
  • Less effective in correcting some vision problems, such as high degree of astigmatism
  • Higher rate of infection

Rigid Gas Permeable

  • Optimal vision correction for many conditions
  • More durable
  • Less frequent replacement needed
  • Allows more oxygen through to the eye
  • Users need time to adjust to the lenses
  • Re-adjustment necessary any time you stop wearing them for an extended period
  • May slip off the centre of your eye more easily;
  • Can lead to discomfort and blurred vision
