What Type of Contact Lenses Are Best For Astigmatism?

Contact Lenses are thin translucent lenses placed just above the cornea on the eye’s surface. They are convenient and comfortable because they offer a great deal of control when changing the focus of vision. There are four classes of contact lenses: Soft, Transfocal, Particulate, and Rigid. Soft contact lenses contain less than 0.2% soft protein and have a watertight seal with the external shell. Transfocal contact lenses have a plastic tube within them and have two different prescriptions inside, the patient slides his or her finger under the plastic tube to get the correct lens prescription, then puts his or her finger back into the tube to take the lens out.

Contact Lenses are used for a variety of reasons, such as to correct vision, like eyeglasses, or to enhance vision, like bifocals. They are also worn by people who have had surgery to replace one or more of their eyes, like those with a detached retina or corneal ablation. Some contact lenses are disposable, but many people prefer to wear a pair year-round, and then switch to a new pair every six months. These types of contact lenses are called bifocals. Rigid contact lenses are usually prescribed for short-term use and are the most popular type of contact lenses.


Contact Lenses for Astigmatism

If you have astigmatism, you may want to try a pair of disposable lenses. However, if you have severe astigmatism, you will most likely be interested in a pair of gas-permeable lenses. Gas-permeable contact lenses have no wick, so they do not produce any air bubbles, so there is no problem with bacteria transferring from your hands to your eyes and no problems with smudges on your glasses. You just put the disposable lenses in your eyes before bed and remove them in the morning. A great benefit of these lenses is that they have a longer life expectancy than other forms of contact lenses.


Prescription Contact Lenses

If you have frequent eye infections, or your vision has been deteriorating for some time, your optometrist may recommend that you start using contact lenses. Prescription lenses can help correct problems with astigmatism, nearsightedness, farsightedness, or astigmatism altogether. However, you must have them cleaned at least once a month and you will probably have to return for follow-up visits. To find out what kind of lens is best for you, your optometrist will do a test to see which one has the lowest astigmatism correction rate.



Sometimes, people with keratitis have red, itchy, flaky skin in the corner of their eyes. If you notice this happening, your optometrist will likely prescribe antibiotics for your condition. These drugs will help to reduce the number of bacteria on the skin that causes the inflammation, making your eyes feel much better. You should also practice proper eye care when it comes to your contact lenses since keeping them clean and properly maintained can prevent problems from developing.


Gas Permeable Contact Lenses

If you need lenses that offer a higher level of water permeability than standard gas permeable lenses do, then you will probably want to try gas permeable lenses. This type of lens contains a small amount of gas-permeable fluid that allows a smaller amount of oxygen to pass through the cornea. Because you cannot see any air bubbles through a gas-permeable contact lens, they are great at eliminating most of the visual irregularities that occur with corneal ulcers and the like. However, they do not solve the actual problem of drying out the cornea and preventing moisture from reaching the eye. For this, you will likely want to use a traditional, non-permeable lens.
