Different types of Contact Lenses

 

Everyone has a choice and if you just happened to choose contact lenses, that’s a good choice. Most people don’t want to go with glasses as it sits on the face, or LASIK surgery.

 

Types of contacts

Contact lenses differ from one another based on  materials. There are 5 types of contact lenses and based on this knowledge, you can choose the one that fits you best.

 

1.      Silicone Hydrogel lenses

These are the most popular types of lenses. They are made of a type of innovative soft lens material that allows oxygen to pass through them. The oxygen then reaches the front surface of the eye.

 

2.      Hybrid contact lenses

These lenses are designed in such a way that provides better comfort than soft silicone lenses. They are surrounded by a layer of hydrogel or silicone hydrogel material and have a rigid permeable central zone.

 

3.      PMMA lenses

These rigid lenses look like GP lenses but differ because they’re made of plastic that doesn’t permit oxygen. PMMA were usually prescribed years ago but GP lenses took over.

 

4.      Gas permeable lenses.

A.K.A GP or RGP lenses are rigid contact lenses that stay on the eye maintaining shape. This enables them to correct astigmatism or other refractive errors. GP lenses are made of highly oxygen-permeable materials. It takes a little time getting used to them but once that happens, you might find them better than soft lenses.

 

5.      Soft lenses

They are made from Hydrogels, they are something like gel-water containing plastics. They are very thin and easily stay on the eye making them extremely comfortable.

 

There comes disposable lenses too like Acuvue1 Day Moist, biofinity six pack monthly, etc. Once you get used to lenses you will know how easy it is with them. If you experience discomfort or something else, visit a doctor.
