1. Soft Contact Lenses
Soft contact lenses are the most popular amongst the majority these days. It is made of flexible plastic that allows oxygen to pass through the cornea. It is more comfortable and easily adjusted compared to rigid gas permeable lenses. Nowadays, they are made of silicone-hydrogels to provide more oxygen flow.
2. Rigid Gas Permeable (RGP) Contact Lenses
Rigid gas permeable contact lenses (RGPs) take some time for a wearer to get used to due to its rigid nature. However, they are more durable and resistant to deposit buildup, and generally give a clearer, crisper vision. They tend to be less expensive over the life of the lens since they last longer than soft contact lenses.
3. Extended Wear Contact Lenses
Extended wear contact lenses are usually soft contact lenses. They are meant to be worn overnight or continuously wear ranging from one to six nights up to 30 days. Your eye care professional will first evaluate your tolerance level and he/she will determine the suitable duration to wear.
4. Disposable (Replacement Schedule) Contact Lenses
People obviously treasure convenience; therefore it comes as no surprise that the most popular contact lenses are the disposables. They need not be cleaned and disinfected as compared to regular ones, hence the advantage of complete convenience.
