Toric lenses are designed for people with astigmatism. Astigmatism refers to the shape or curvature of the cornea or lens of your eye. Ideally, your eye should be completely spherical. But if you have astigmatism, your eye is more oval, like the shape of an egg. This prevents light from focusing properly on the retina, causing blurry vision both at a distance and up close.
Toric contact lenses for astigmatism differ from other contact lenses in that they have additional work to do. “Normal” contact lenses, such as sphere, correct only nearsightedness (nearsightedness) or farsightedness (farsightedness). But if you have astigmatism, your vision can be blurry at any distance. To correct this, toric contact lenses place different color blind clip on glasses
powers of prescription lenses in different orientations of the contact lens. This was difficult to do well because the contact lenses move around your eye while you are wearing them. However, modern toric contact lenses have design features that keep the lens in the correct position.ii
Do you need a toric lens?
If you have astigmatism, you may need a toric lens if you wear soft contact lenses to achieve the best possible visual performance.
Fortunately, toric contact lenses have come a long way in recent decades. Today, there are numerous toric soft contact lenses in a wide range of prescriptions to fit all types of eyes, even if you have presbyopia too!
Modern Soft Toric Contact Lenses
Soft toric contact lenses are now available in a variety of materials (such as silicone hydrogel) and replacement schedules (such as daily disposables). You can even get toric contact lenses in multifocal designs (for presbyopia). These remarkable advances in contact lens technology make it easier than ever to stop relying solely on glasses. Of course, you should always have a spare pair of glasses in case of an emergency, but with the right toric lenses you can enjoy most of your time without them.
