Isometric cheapest eyeglasses lenses are mainly used to solve the problem of the inability of both eyes to fuse images when patients with anisometropia look far. Regarding the principle of isometric lenses.
Precautions for fitting anisometropia: Many friends who have been fitted with imaging lenses may still experience visual fatigue problems. How to solve the details of visual fatigue problems through imaging lenses to avoid failure.
Firstly, we need to understand why anisometropia can cause visual fatigue. The imaging size of anisometropia is different, and the two eyes cannot merge images. There is no stereoscopic vision; only one eye can see up and the other can see far. Isometric cheapest eyeglasses lenses are mainly used to solve this problem.
Refractive anisometropia is generally accompanied by strabismus. The lens itself has a prism effect, and the improper frame selection is a prism problem.
At the beginning of image fusion, there is a period of adaptation, and the fatigue caused by working both eyes at the same time will gradually improve. How to avoid problems and achieve the best effect with imaging lenses.
Fitting is of utmost importance and the soul of fitting the cheapest eyeglasses lenses. Isometric lenses require binocular correction, astigmatism correction, and precise axial alignment. These are the fundamental principles for fitting both isometric and regular lenses.
The frame should be selected with a nose support, which can be adjusted appropriately. The frame and rim should be selected within 50 ➕ Mid distance between your pupils, the closer it is to your pupil distance, the better the effect when worn.
That is to say, first know your pupillary distance and choose a frame based on it. In addition to providing the degree of foot correction, it is also necessary to have the distance between the pupils of one eye and the height of the pupils.
