Biomedics Toric Contact Lenses

For people with astigmatism, a biomedics toric lens can correct the condition. Loosely defined, astigmatism is an error in the refraction of light within the eye. This error creates a visual disturbance. Astigmatism is usually caused by a misshaped cornea or lens (the area behind the cornea.) It is the most common vision problem and not very serious but can be corrected with a Biomedics toric lens.

There are several ways to treat it, including using biomedics toric lenses, glasses or refractive surgery. If it is never treated, the patient may experience eyestrain, headaches or blurred vision.Toric lenses are made in two types: soft lenses or RGP (Rigid Gas Permeable). It used to be that people with astigmatism could not wear lenses, but that is no longer the case. However, fitting toric lenses to your eyes does take some extra effort, because they are created with curvatures from two different angles for correcting both astigmatism and myopia (nearsightedness) or hyperopia (farsightedness). They are also manufactured so that they don’t slip around on your eye or rotate when you blink. As a result of staying put on the eye, the toric lenses provide crisper, clearer vision.

Toric lenses by companies such as Biomedics cost more than regular, spherical lenses, and having them fitted to your eye will also be more expensive than most contact lens fittings. But if you have astigmatism, it is well worth it. You can purchase Biomedics toric lens in several colors and types: disposable, frequent use, daily wear and non-disposable. Your ophthalmologist will tell you which type is the best for your particular condition. If your astigmatism is minor, you may be able to wear standard spherical lenses after all.

Not so long ago, people with eyes shaped more like footballs instead of like soccer balls were told they could not wear contacts because of their corrective needs. Advances in contact lens technology have now made it possible for people with astigmatism to break free from the hassle of glasses, and to even enjoy soft contact lenses, colored contacts, and multi-focal contacts. Biomedics toric contacts make it possible for even the most oddly shaped eye to enjoy total correction and total comfort. Produced by Ocular Sciences, Biomedics toric contacts combine comfort and versatility to deliver visual acuity to even the most severely astigmatic eyes.

Made from the same material as other contact lenses, toric lenses depart from the norm in how they are curved. Since correcting astigmatism means accounting for an unusual bending of the eye, in addition to correcting either nearsightedness or farsightedness, toric lenses are aspheric and created with curvatures at different angles. Sometimes they have different thickness along their edges to act as weights that help keep the lens from shifting about on your eye as you blink.

Toric contacts are available in a variety of formats: frequent replacement, disposable, and even daily disposable lenses. What’s more, you can even get colored toric lenses that can give you the blue, green, even brown eyes you always wanted. There are even multifocal Biomedics toric contacts that can correct for presbyopia, the condition that typically affects aging eyes and translates into difficulty focusing on objects when they are up close.
