What are the different types of contact lenses astigmatism?

Many people wear contact lenses as an alternative to the glasses to repair their vision. Astigmatism contact lenses differ from other types of contacts due to their irregular shape. They can be soft or rigid and also differ if and how long they can be worn before they must be replaced. While glasses can usually also correct all these problems, many people prefer contacts for several reasons. Some advantages of contact lenses are their durability, ease of use and the fact that they can sometimes correct the vision more efficiently than glasses.

astigmatism is a condition caused by an irregularly shaped cornea. Some of the main characteristics include blurred vision and a distorted view of objects. People with astigmatism usually require toric contact lenses. The toric lens is curved to correspond to the unique shape of the cornea.If the fact that people often experience either myopicity or foresight together with astigmatism, a toric lens usually contains two different Sof a pitch. One of the advantages of contact lenses of astigmatism is that their unique design is usually maintained better than standard lenses. The potential disadvantage is that they are relatively more expensive.

There are basically two types of toric lenses for astigmatism-soft lenses and solid lenses (RGP). Soft contact lenses are made of water and flexible plastics called hydrogels that allow oxygen to achieve cornea. Another option that has recently been available is the silicone hydrogel lens , which allows even more oxygen to reach the cornea due to silicone throughput. While conventional soft lenses tend to match the shape of the eye, so they are less effective in repairing astigmytism, soft toric lenses are specially designed to help improve someone's vision.

On the other hand, they are usually made of a combination of conventional plastic and silicone and are only slightly flexibil. They tend to better maintain their shape on the eye and also allow oxygen to reach the cornea. Although most patients prefer the comfort of soft lenses, some vision experts recommend rigid lenses for what they consider to be a better vision of being corrected.

As soon as someone decides on soft or rigid contact lenses astigmatism, they can choose lenses based on how often they must be replaced. Some types include daily disposable, which are worn for one day and discarded. Other contacts can be left during sleep and overnight. Some can be worn for several days or weeks, except for sleeping and then replaced at regular intervals. The lenses of extended wear can be worn for several days, including overnight. Yet, even ISE should still be removed once a week and regularly replaced. Continuous wear lenses can usually be worn up to 30 days.

It is recommended that someone who wears contact lenses of astigmatism has a proper professional assembly andHe regularly visits his eye doctor to ensure the proper functioning of the contacts. People with mild astigmatism may not need toric lenses at all. Standard lenses can be able to transform the cornea just to repair astigmatism, along with myopia or foresight for which they are also prescribed.
