If the near eye position is within the normal range, adults can decide according to their needs, and kids eyeglasses online and adolescents cannot lower it.

Look up at the implicit tilt of the eyes that exceeds the normal range, and looking up can reduce the degree. Look closely at the external oblique angle that exceeds the normal range, and look closely without reducing the degree.

Based on the AC/A value, it can be roughly determined that:

The AC/A value is within the normal range of 3-5, and adults can reduce it appropriately according to their needs. Children and adolescents should maintain normal myopia function and delay the increase of myopia kids eyeglasses online degree by not reducing the degree of myopia.

If the AC/A value is less than 3, it indicates that the regulatory set is relatively weak. Do not lower the degree when looking closely, but increase the mediation stimulus, fully mobilize the set, and reduce the possibility of implicit bias.

An AC/A value greater than 5 indicates that the mediation set is excited, which can reduce the degree, weaken the mediation stimulus, slow down the set, and reduce the possibility of implicit skewness.

Of course, in addition to the detailed analysis based on the visual function mentioned above, we also need to refer to the changes in the old and new glasses, individual adaptability, and other factors to assist in determining whether it is suitable to reduce the discount prescription glasses degree of view up close. The degree increased by 300 degrees, and although the opening of the near eye position was very loose, I still appropriately reduced it a little bit, otherwise, I couldn't wear it.
