Correct monocular myopia and don’t give up healthy eyes

Abstract: when correcting monocular myopia, we should pay attention to the preparation of one eye flat lens. In general glasses shops, when correcting monocular myopia, only one eye of myopia is paid attention to, and only a qualified flat lens with the same color and brand is casually installed on the healthy eye., Due to the correction of myopia, the glasses are matched according to the lowest degree of the best vision, and in principle, the standard is 1.0. The eyesight of emmetropia is 1.0, 1.5 and 2.0, that is, normal eyesight, standard eyesight and super standard eyesight. While correcting monocular myopia, we should also carefully check the near and far vision of healthy eyes. If the far vision of the healthy eye is 1.0, the correction of one eye vision for myopia shall not be greater than 1.0. If the vision of the healthy eye is 1.5 or 2.0, the correction of one eye for myopia can be slightly greater than 1.0. Neither let the corrected visual acuity exceed the healthy visual acuity, nor let the visual acuity difference between the two eyes be too large, otherwise it will be restrained by the healthy eye and can not achieve the ideal visual effect., When correcting monocular myopia, attention should also be paid to the preparation of one eye flat lens. In general glasses shops, when correcting monocular myopia, only one eye of myopia is paid attention to, and only a qualified flat lens with the same color and brand is casually installed for the healthy eye. However, this approach is not ideal. Because the qualified flat lens still has a relative top focus in the national standard GB10810-1996 spectacle lens & plusmn; Tolerance of 0.08d ‘and slight prismatic tolerance. When used in conjunction with monocular refractive correction, the requirements should be more stringent than ordinary flat lenses. Since the wearing time of corrective glasses is longer than that of ordinary flat goggles, in order to achieve a more ideal and comfortable effect, we can also make a reasonable choice of these tolerances and use them to make more accurate balance correction in clinical practice. Here are two examples: Example 1: for example, the near vision of the patient’s right eye is 1.5, the far vision is -2.50ds = 1.0, the near vision of the left eye is 1.5, and the far vision is normal 1.0. This shows that there is myopia of -0.25d in the left eye. Although it is not corrected, qualified lenses within 0.00 to -0.08d can be selected from flat lenses, and qualified lenses within 0.00 to + 0.08d can not be selected. This can reduce artificial myopia within 0.08d. If the measured lens has slight prismatic degree, the bottom tip line should be installed in the horizontal direction outward from the base, which will make the wearer feel more comfortable., Example 2: for example, the near visual acuity of the patient’s right eye is 1.5, the far visual acuity is -2.50ds = 1.0, the near visual acuity of the patient’s left eye is 1.5, and the far visual acuity is 2.0. This shows that the left eye vision is very standard. When selecting the left eye lens, select the qualified flat lens of 0.00 to + 0.08d instead of the qualified flat lens of 0.00 to -0.08d. In this way, artificial hyperopia within 0.08d can be avoided when looking far, and the adjustment within 0.08d can be reduced when looking close. Since the tolerance of myopia lens in the national standard gb1081-1996 spectacle lens is ± 0.12d, while the right eye -2.50d myopia lens is selected, the qualified lens between -2.50d and -2.62 can also be selected, and the qualified myopia lens between -2.38d and -2.50d is not selected. In this way, the corrected vision of the right eye can be slightly greater than 1.0, so as to reduce the distance between the two eyes. On the contrary, the distance between the two eyes will be too large and lose balance., Due to the correction of myopia,

is equipped with glasses according to the lowest degree of the best visual acuity. In principle, it is up to 1.0 as the standard. The eyesight of emmetropia is 1.0, 1.5 and 2.0, that is, normal eyesight, standard eyesight and super standard eyesight. While correcting monocular myopia, we should also carefully check the near and far vision of healthy eyes. If the far vision of the healthy eye is 1.0, the correction of one eye vision for myopia shall not be greater than 1.0. If the vision of the healthy eye is 1.5 or 2.0, the correction of one eye for myopia can be slightly greater than 1.0. Neither let the corrected visual acuity exceed the healthy visual acuity, nor let the visual acuity difference between the two eyes be too large, otherwise it will be restrained by the healthy eye and can not achieve the ideal visual effect.
