Contact Lenses

Perhaps the most advantageous improvements in contact lenses have been the industry introducing contact lenses for astigmatism. There are two specific types of contact lenses for astigmatism, however, the most popular and favorite is the Toric lens.

Astigmatism occurs when the cornea, the front eye surface has an irregularity in its shape. The irregularity works to prevent proper focus of light the retina, in the rear of the eye. The result is generally blurred vision at any distance. This causes the visual condition known as astigmatism, requiring the need for corrective lenses.

Until recently, those suffering from astigmatism had few choices in correction. While contact lenses for astigmatism did exist in the form of the RGP lens, optometrists were not ready to present these to their patience simply because they were believed to work poorly and have a hard fit.

Therefore, because of this belief and the lack of options, those suffering from astigmatism believed they had no choices. However, because manufacturers have continued to improve on technology and make solid advancements to their lenses, today there are several options for those with astigmatism.

For those suffering from slight astigmatism, such as less than 1.00 D, they can generally get away with wearing soft lenses, having little to no problems with clarity. However, for those with less than 2.00 D, but more than 1.00 D, they will need specialized contact lenses for astigmatism. There are two choices, the soft toric or the RGP (Rigid Gas Permeable) lenses.

Typically, because of costs and production, either type of contact lenses for astigmatism are generally worn for a month before being replaced. Let's have a look at the two different types of contact lenses for astigmatism.

Soft Toric Lenses

Toric lenses are soft, disposable, and come available with low correcting powers for astigmatism. These lenses are for those who can still get away with a softer lens, but have a need for at least 0.50 D correction for astigmatism. For many people with astigmatism, this is the choice contact lens, simply because they are soft and pliable for the wearer.

RGP Lenses

RGP lenses, also known as rigid gas permeable lenses, have improved a great deal in the past years. In fact, thanks to high technological equipment and manufacturing knowledge, they have been able to make a great deal of improvement in both quality and fit for contact lenses for astigmatism.

Choosing the right type of contact lenses for your vision needs will require a consultation from your optometrist. Only the two of you can decide which form of correction will best suit your needs, providing you with a high quality and high performing vision correction.
