Distance Glasses
When a patient sees badly , he spells out special glasses for farsightedness.
In the case where the patient has hyperopia (farsightedness) high (above + 3D) or moderate his prescribed bifocals or a pair of glasses for distance (weaker) and near vision (stronger).
The main problems have far-sighted people begin after they turn 40 years old, as to an existing farsightedness and presbyopia adds another (age weakening eye of accommodation).
Note that the glasses hyperopia in children just need to wear because of their refusal to wear leads to all sorts of dire consequences (strabismus, intolerant points).
The first question that arises from the potential patients: what points do we need when if we have farsightedness?
The answer to this question can only get from an experienced ophthalmologist, after carrying out all necessary investigations.
Selection of glasses when hyperopia requires more attention, both from the patient and by the ophthalmologist as incorrect glasses can only worsen the situation and ultimately ruin eyesight. Let us, and we come to the problem seriously.
How to choose glasses hyperopia
Picking up his glasses for farsightedness, you should consider the distance from the eye to the subject under consideration.
Typically, this distance is approximately 33 centimeters.
Nevertheless, there are professions in which this distance is considerably lengthened. For example, the best distance to the musicians to the equal length of about one meter, and typists prefer to work with the texts at a distance of about 70 centimeters.
Points for this work should be made with weaker glasses that physicians should consider in the selection of points.
In such a case can be made several pairs of glasses, however, it is not always easy to deliver to the client.
Many patients prefer to use bifocal (combined) points when they are working. Glass of points consist of two distinct halves: the bottom - for others, and the top - for long distances.
Such glasses can walk continuously while looking at distant objects and nearby images.
