Contact lenses or contact lenses are one of the most used options in the world to correct refractive defects such as myopia, farsightedness and astigmatism. Many people prefer to wear contact lenses because, unlike glasses, they have more campor visual and they can see much better. 

En Área Oftalmológica Avanzada We explain what the different types of contact lenses are and what each of them is recommended for.

What are contact lenses? 

contact lenses

Contact lenses are a type of thin, curved lens that fits over the ocular surface and that covers the cornea. The lenses are usually transparent, but sometimes they have a little print on them. color for easy handling and identification. 

Colored contact lenses are for one purpose only aesthetic and its elaboration is totally different from that of contact lenses to correct refractive errors. 

Types of contact lenses 

Currently there are three type contact lenses:

Soft

Soft contact lenses are the most commonly used and are recommended for people with refractive errors with moderate graduations. They are called soft because they are made to be more perfect y flexible, and thus can be used for several hours. 

Soft contact lenses for occasional or temporary use are ideal for those who want to combine the use of glasses and the use of contact lenses. Among the variety of soft contact lenses we find: daily, biweekly, monthly and prolonged use

semi-rigid

They are lenses that in their central area are made of rigid gas-permeable material, but the outer ring is soft. They are recommended for patients with a curvature of the irregular cornea, an abnormality caused by a disease such as keratoconus

Rigid

Rigid lenses are recommended for people with astigmatism who need a harder lens that adapts better to the eye or patients with pathologies that cause irregularity in the cornea. 

What defects do contact lenses correct?

Contact lenses are used to correct the following refractive errors:

Astigmatism

This defect causes blurred vision, caused by an abnormal curvature of the cornea. Contact lenses for astigmatism are divergent design y o-ring to help correct the eye. 

Farsightedness

contact lenses for farsightedness they do not change position once placed in the eye, this offers a more stable vision. The material of these lenses is much more delicate than the rest. 

Myopia

All the contact lenses for myopia control sound divergent design, that is, the thickness decreases from the edge to the center so that when light rays are perceived they separate from each other. contact lenses for myopia they modify the shape of objects that may appear smaller than in reality. 

Presbyopia

All the multifocal lenses or bifocal lenses allow to correct presbyopia thanks to the fact that they have two graduations in the same lens, whether to focus images at short, medium or long distance. The lenses for presbyopia can be rigid o soft
