Everyone has seen the specs, but not everyone wears them from morning until evening.
How nice and helpful eyewear is – this is debatable – many are bored with their helplessness without them, others by the inconvenience during sports and other mobile activities, but when your vision depends on them, you must not be capricious. Or maybe you do?
For a long time on the market, there are small and inconspicuous substitutes for glasses – contact lenses. They are divided into two main types – soft and hard. Soft lenses have a much greater application in eye practice because they are physiological.
Their selection should not be done indiscriminately, as it is necessary to adhere to several indicators – radius, diameter, diopter, and the type of material. Last but not least contacts comply with the occupation of the patient. Lenses should not be over worn. In general, the patient must comply with several rules when wearing lenses, and also follow the doctor’s instructions.
In one year of use the lenses need to be properly cared for: disinfected and cleaned by a special solution. The main problem occurs if there was no good maintenance or one of them stop “working” properly.
For the last 5 years the range of parameters of these lenses has grown. The lenses have acquired other qualities – UV protection, corrections astigmatism, huge selection of colors, and lenses with unusual views – Crazy and Wild eyes.
The advantages of lenses compared to glasses are that they provide much better visual acuity and no field restriction. Having in mind the quality and materials which they are produced from, the contact lenses provide a significant comfort. Glasses naturally remain in practice, they also have their place, but contact lenses are preferred mostly by young people, ones with high diopter and those who have a significant difference in vision between both eyes, which cannot be corrected with glasses, as they raise separation of images from both eyes in the cerebral cortex.
What to choose – glasses or contact lenses? Everything depends on the patient’s age, on his/her profession, and are there any medical indications for wearing contact lenses. If the one in need of a means of vision correction is an athlete for example, of course, the contact lenses are better than glasses. Lenses are not recommended for people with certain eye diseases or when their side effects have already occurred – allergic reactions and others. Of course, everyone who uses contact lenses should have a pair of glasses – as a backup.
The reasons for which we give up on glasses and try contact lenses are various. Some people are unsatisfied by their appearance or they try to make their life more convenient. Others are willing to change their look and attract other people’s attention. Whatever the causes are to resort to the lens, the glasses have their advantages. They make us look more intelligent and charming.
