Contact lenses for short-sightedness are spherical lenses with negative powers. They are a medical device, therefore they should always be chosen in a reputable ophthalmic salon. Only on the basis of a thorough eye examination is a specialist able to determine the degree of intensity of the defect, choose the appropriate power of lenses, and also exclude any possible contraindications to wear them.
Shortsightedness, also called myopia, is a visual defect that is the result of an inadequate shape of the eyeball. In short-sighted people, it is too long, so the light rays entering the interior of the eye, focus in front of the retina, instead of on the retina (as in the case of a healthy eye). It is the ophthalmologist who should determine that the reason for the worse vision is short-sightedness. Which contact lenses to choose is the most common question that appears in people who are opting for this method of correction. For the treatment of myopia, spherical contact lenses with negative powers are used, i.e. the so-called minuses.
Medical history
Comprehensive vision examination, extended by the choice of lenses, consists of several stages. The first one is an interview with a patient. Topics most often asked by the doctor include: occupation, visual ailments, current and past diseases, medications used or possible earlier methods of correction of vision defects.
Vision examination
After a medical interview, the specialist undergoes a preliminary examination during which he or she determines, for example, the quality of vision from near and far, as well as intraocular pressure, using specially designed equipment, i.e. a tonometer. During the visit, the patient also undergoes a computer vision examination, necessary to select lenses, because it allows to determine the radius of curvature of the cornea, as well as to accurately measure the refraction of the eye. For precise medical diagnosis of the health condition of the eyes and possible contraindications to wear lenses, it is also necessary to analyze the crevice lamp. The examination determines, among other things, the quality of the tear film, as well as the state of health of the cornea, conjunctiva, eyelids, iris and eye lenses.
Fitting the test lenses
If there are no contraindications to wear lenses, the ophthalmologist shall evaluate the parameters and type of test lenses and apply them in front of the patient. After a certain period of adaptation, the specialist assesses, among other things, the quality of vision, the comfort of use and the fit and centering of the lens.
Types of contact lenses for short-sightedness?
While lens parameters are chosen by an ophthalmologist, the decision about the mode of wearing them depends on the patient's individual preferences. Contact lenses can be worn monthly, meaning one pair of lenses is worn for 30 days and require daily care and cleaning. Day-old lenses are a disposable, more hygienic product that is replaced by a new one every day.
