Contact lenses Torics for Astigmatism

Do you have astigmatism? Then toric lenses are for you. Astigmatism is one of the most common visual defects and nowadays there are lenses for nearly all types of astigmatism, whether you aremyopic or hyperopic. Visit your optician and try toric lenses and find a type that suits you and your lifestyle!

Toric biweekly or monthly lenses are very comfortable and easy to get used to through daily use. They are made from a material called Hydrogel and contain 38-75% water. Simply put them in in the morning and take them out at night for cleaning and storage. When you have used them for 2 or 4 weeks (depending on the type you purchase) replace them with a fresh clean pair.

Extended wear lenses

Forget you even have astigmatism with toric extended wear lenses! For up to four weeks at a time, you can wear your contact lenses without changing them. Hydrogel lenses often do not let enough oxygen through for you to be able to wear them longer than a day. If you sleep with normal lenses in, your eye will have a lack of oxygen and can become infected. But now it is possible to sleep with your lenses thanks to the fantastic material Silicon Hydrogel. They let in six times more oxygen to the eye than regular lenses allowing the eye to breathe. Sleeping, partying, traveling and working with them; you can do whatever you want for as long as you want!

Toric daily disposable contact lenses - flexible and comfortable

Toric daily disposable contact lenses are for those who do not want to think about cleaning and storing their lenses. Every day you open up a fresh pair of lenses that you then throw them away in the evening. Do you use glasses? It's always good to have a pair of toric daily disposable contact lenses for special occasions, when you train, use sunglasses or

go to a party and you want to accentuate your makeup.

The cornea is a transparent tissue that covers the front of the eye. Apart from protecting the eye from damage it is responsible for focusing incoming light onto the retina. The retina is in the back of the eye and when light rays hits it they are transformed into electrical signals that are sent to the brain which converts them into a clear image. For this to work properly, the cornea must be perfectly curved, much like half of a football. A person with astigmatism has a cornea that is uneven and more resembles the shape of a rugby ball. When light rays hit, the cornea does not focus them properly on the retina and vision is blurry for both near and far.

Astigmatism is a very common eye defect affecting both children and adults. In fact many people have astigmatism without knowing it! In these cases the refractive error is often so small that you do not need to correct it. If you have more developed astigmatism you may also have the side effects of eye strain, fatigue and headaches. Astigmatism is easily corrected using toric lenses whether you are hyperopic or myopic.

The design of toric contact lenses

Astigmatism is due to an uneven refraction of light from the cornea to the retina. Toric lenses have a different power at the specific angle your eye needs help with. It is therefore important that the lens stays in place and does not slide around. For this to be possible, toric lenses have a built-in weight that reacts to gravity so you don’t need to worry about putting your lens in upside down. If you have toric lenses, you have probably noticed that your vision is blurred after lying down for a while and this is because the gravity acting on the lens has changed with your position.
