Bifocal Contact Lenses for Astigmatism

Contact lenses are most commonly used in the field of vision correction and healing. Contact lenses are used for treating or reducing effects of various eye problems and vision insufficiency issues. There are various types of contact lenses that are prescribed to treat various eye problems. One of the common eye problems that are cured with help of contact lenses is, astigmatism. Astigmatism is a medical condition which is related with irregular shape of the cornea that leads to vision problems. There are various types of astigmatism contacts that you can use. Presbyopia, on the other hand, which is an age related eye disorder demands special type of contact lenses. Till a few years ago, a person who suffering from both, astigmatism and presbyopia had to wear astigmatism contacts and specs. However, things have changed now, and you can opt for bifocal contact lenses for astigmatism and presbyopia. Let's get to know more about it.

Condition of Astigmatism and Presbyopia

Before finding more information about presbyopia and astigmatism contacts, let's find out more about both these medical conditions. Many people suffer from astigmatism, which is a corneal medical condition that causes irregular shape of the cornea. Due to this irregular shape, regular contact lenses are useless for such people and hence, they need to choose toric contact lenses that are of two main types, namely, soft toric contact lenses and rigid gas permeable (RGP) contact lenses. You can also find colored contacts that correct vision and also provide a cosmetic appeal to your eyes. Presbyopia, which is a monovision problem, is a condition in which a person suffers blurred vision for closer objects, which is a common occurrence after the age of 40 years. To get relief from this vision problem, a patient needs to wear near vision specs or contact lenses.

They also have a great option available in the form of bifocal contact lenses, that are also known as multifocal contact lenses. These lenses have two focal points and are useful for both far away and nearer objects. There are two types of bifocal contact lenses, namely, alternating or translating vision bifocal lenses and simultaneous vision bifocal lenses. The simultaneous vision lenses have alternating concentric rings that prove helpful for myopia as well as hypermetropia. The translating vision lenses on the other hand have the faraway focal point set right at the top of the lens. It means, when a person wearing them looks in upward/forward direction, he 'activates' the distance power and when he looks downwards he sees nearer objects more clearly. These are not disposable contact lenses and they are not available without prescription as well.

The Best Lenses

When an astigmatic person suffers with presbyopia, he either has to opt for bifocal eyeglasses or bifocal toric contact lenses for astigmatism. You will find both hard (RGP) and soft bifocal contacts for astigmatism. However, you need to understand that bifocal translating vision lenses are often RGP lenses and the bifocal simultaneous vision lenses are soft lenses. But you will not find disposable contact lenses with bifocal and toric properties. Bifocal toric contact lenses for astigmatism are specially designed lenses, with slight modification in the existing design of toric lenses. Originally, toric lenses are heavier at the bottom, which stops their rotation inside the eye. However, toric bifocal lenses with RGP power are suitable to cure severe type of astigmatism and they also avoid rotation which causes problems in clear vision. Soft lenses are used for the treatment of minor type of astigmatism. Another type of contact lenses that are prescribed for astigmatism and presbyopia patients are aspheric contact lenses. These contact lenses are suitable for patients of borderline astigmatism and presbyopia.

There are various popular brands that sell prescribed contact lenses for astigmatism and presbyopia. You will definitely get good deals in such brands. Some popular brands for bifocal toric lenses are Ciba Vision, Acuvue, Coopervision, etc. The best thing that you can do is, go through toric contact lenses reviews as well as bifocal contact lenses reviews.
