Astigmatism: what it is and how to correct it with contact lenses

Astigmatismo: cos’è e come correggerlo con lenti a contatto

There are 18.7 million people in Italy, of whom 2.4 million are young, who have vision problems and suffer from visual impairments.

According to a Censis report from 2012, 2.8 million people in our country are affected by astigmatism, according to the National Federation of Opticians and Optometrists. What exactly are we referring to when we use the word astigmatism?

What is astigmatism, how to identify it, and how to treat it

L’astigmatismo (dal greco ἀ-, ἀν- a, an, mancanza, privazione; e στιγμή stigmé, punto, cioè “non puntiforme”) è un’ametropia, ossia una patologia oculistica che si presenta quando il sistema oculare non è in grado di formare un’immagine puntiforme di un oggetto puntiforme.

L’astigmatismo è un difetto visivo che si manifesta quando la cornea, ovvero la membrana trasparente che ricopre la parte anteriore dell’occhio, non ha la stessa curvatura in tutti i suoi punti.

Qual è la conseguenza? L’immagine che verrà visualizzata sarà distorta e offuscata; la visione apparirà poco nitida sia da lontano, sia da vicino. La logica conseguenza è non riuscire a mettere bene a fuoco le immagini e arrivare ad affaticare la vista, strofinando spesso le mani sugli occhi.

Tramite la misurazione del potere refrattivo della cornea o una mappatura elettronica della stessa, l’oculista può facilmente individuare la problematica. Se il responso della visità dirà che la misurazione dell’astigmatismo va da 0 a 1 diottrie significa che siamo di fronte a un problema classificato come lieve. Se invece le diottrie superano il valore 2, la problematica è classificata come grave.

Ma come curare quindi l’astigmatismo? Le scelte potenziali sono tre: occhiali correttivi, chirurgia corneale LASIK oppure lenti a contatto. Vediamo in che modo trarre vantaggio dall’utilizzo di quest’ultime.

Contact lenses for astigmatism

Taking good care of your contact lenses is essential for their proper functioning and for the health of your eyes. One example of a good practice for multi-use lenses is to always remember to fill the contact lens case with disinfecting solution. Before placing the lenses in their case, it’s a good idea to put a few drops of cleaning solution on the lens after removing them, ensuring they stay clean and are ready for use in their full efficiency.

It’s also important that the lenses are always fully immersed in the solution. For good hygiene, it’s a good practice to rinse the lens case every day as well.

If you prefer lenses that are not multi-use, no problem—simply purchase disposable contact lenses, which are designed for single-use only.
