With farsightedness (hypermetropia), a person sees distant objects well, but his eyes cannot focus on nearby objects. At the same time, it is difficult to write, work at a computer and read, especially in small print.
The main symptom of farsightedness is poor near vision. But besides this, overstrain of the eye muscles, discomfort in the eyes, headaches and even nausea can be felt. As a rule, the visual symptoms of hyperopia are not as obvious as with myopia, and patients may not notice that they have vision problems for a long time. But it's time to go to an ophthalmologist if your eyes get very tired and your head hurts with prolonged eye strain.
Correction of farsightedness will allow you to see well in any conditions and at any distance, reduce the discomfort caused by tension in the eye muscles. Hypermetropia in children should be corrected as soon as possible, since farsightedness detected at an early age can be cured, and the lack of correction can lead to the development of strabismus and amblyopia (weakening of vision in one eye, the so-called "lazy eye").
As a rule, it is caused by a reduced size of the eyeball, due to which the light rays are focused not on the retina, but behind it. Most children are born with farsightedness, which goes away as the eyeball grows. Sometimes she associated with the features of the refractive power of the optical system of the eye.
In addition, there is presbyopia or age-related farsightedness, when people over 45 begin to have difficulty focusing their vision on close objects, for example, when reading. It is believed that this is due to the loss of elasticity of the lens of the eye.
For correction, glasses or contact lenses can be used, which will allow light rays to be directed to the retina to form a clear image.
Contact lenses are the most convenient way to correct hypermetropia. They are worn directly on the eyes and form an integral optical system with them, allowing you to improve your eyesight and see well. The shape allows you to direct light exactly on the retina, for this the center of the lens is made thicker than its edges.
Lenses do not restrict the field of view, do not fog up and do not fall off the nose. You can play sports, dance, work, meet friends in them – it is always good to see, and at the same time no one will guess that you have vision problems.
There are different wearing modes, you can choose the best option for any work and leisure schedule: day mode, < a href="/catalog/linzy-nochnye-nepreryvnogo-nosheniya/">flexible, extended a> and even continuous up to 30 days without removing.
Selection should be carried out by an ophthalmologist. He will check your vision, make sure that contact correction is possible and write out a prescription for lenses, according to which you will buy and order them in the future. The optical power of contact lenses for hyperopia is indicated with a “+” sign with one or two digits separated by a comma.
Remember that any visual and associated discomfort is always a reason to contact an ophthalmologist. Those who already wear glasses or contact lenses should have their eyes checked at least once a year.
You can contact optics salon: you will have your vision checked by a professional ophthalmologist, find out your contact lens parameters, and write a prescription for them. Often in salons that deal with contact correction, there is a fitting service: it will allow you to choose the most comfortable option. At the same time, you will be taught how to remove and put on lenses, how to handle them, and help you choose a solution for storage and accessories.
