<\/span>Introduction<\/strong><\/span><\/h2>\n\n\n\nContact lenses are thin\u00a0artificial lenses, which are\u00a0directly\u00a0placed on the\u00a0front\u00a0surface of the\u00a0eye. They help improve vision in people\u00a0by covering irregularities or surface problems of the cornea 1<\/a>,2<\/a><\/sup>.^{<\/sup>They may\u00a0be a\u00a0convenient\u00a0alternative\u00a0choice\u00a0for spectacles, as they provide\u00a0a wider\u00a0field of vision and appear more natural.\u00a0<\/p>\n\n\n\n}
In recent years, contact lenses have\u00a0gained\u00a0popularity, especially among\u00a0new users, due to increased comfort,\u00a0availability of\u00a0different types,\u00a0and ease\u00a0of use.\u00a0Still,\u00a0many are\u00a0doubtful\u00a0about\u00a0its safety and worried about its side effects.\u00a0\u00a0<\/p>\n\n\n\n
In this article, we will discuss contact lenses in detail, including their types, uses, safety, and side effects. This may help you understand whether contact lenses are suitable for you and clear up common misconceptions about their use.\u00a0<\/p>\n\n\n\n

<\/span>What Are Contact Lenses?<\/strong><\/span><\/h2>\n\n\n\n
Sometimes,\u00a0our\u00a0eyes\u00a0cannot bend and focus the\u00a0light properly\u00a0onto the\u00a0retina\u00a0(the part of the eye which forms images).\u00a0As a result, the image might not form in the right place,\u00a0making it look blurred or out of focus. This is called\u00a0a refractive\u00a0error.\u00a0\u00a0<\/p>\n\n\n\n
As mentioned earlier, contact lenses\u00a0are thin artificial lenses placed directly on the eye surface.\u00a0They\u00a0work by correcting this refractive error,\u00a0which might help the light enter the eye in the right way, making the images appear clear and\u00a0accurate 2<\/a><\/sup>.\u00a0<\/p>\n\n\n\n
Contact lenses\u00a0are\u00a0mainly used\u00a0to correct vision problems such as myopia (short-sightedness), hyperopia (long-sightedness), astigmatism (blurred\/imperfect vision), and presbyopia (difficulty focusing on near objects). There are\u00a0many types of contact\u00a0lens available with\u00a0two\u00a0major types\u00a0being\u00a0hard and soft contact lenses 1<\/a>,2<\/a><\/sup>.<\/p>\n\n\n\n
