Some people think it looks better with glasses, and the glasses may even be a fashion accessory, but other people avoid wearing glasses, and contact lenses are the ideal solution, managing to give up their glasses without having to intervene surgery.
Problems of vision
Problems of vision are encountered in a fairly large number of people, whether they were born at birth or with the passage of time. Regardless of the age at which you find yourself suffering from an ocular disorder, it is absolutely necessary to correct your vision with the appropriate diopter.
If you have been wearing eyeglasses for a while, and now you want to try contact lenses, a new ophthalmic / optometric control is required, as the diopter you wear on eyeglasses may be different from lenses contact.
This is due to the vertex distance (the distance between the lens and the eyeball). If in the case of contact lenses, the distance is non-existent, being applied directly to the eye, for eyeglasses, the distance between them and the eye is about 12 millimeters. This means that diopters will also be different. Generally, people with a diopter of between 0 and -3 in sight glasses also have contact lenses of the same diopter, with the difference being the case for those with larger diopters.
But because each case is particular, when choosing to switch from eyeglasses to contact lenses, it is necessary to consult an ophthalmologist / optometrist. He can tell exactly what type of lens you fit, according to the specific needs of your eyes. Not all contact lenses fit you and you need to keep in mind some details to make the best choice:
- Contact lenses can correct myopia, hypermetropia, astigmatism or the combination of the three diseases;
- Contact lenses have to match your eyes, they are on the market in hundreds of combinations of diameter and curvature;
- Before choosing your contact lenses, you need to know if you wear them at all times (even at night) or if you want to wear them only during the day or just for certain events. For each of these options, another type of lens, made from different materials, must be chosen.
