If the new cheapest eyeglasses still feel clear within one week but are uncomfortable and the symptoms have not improved, then these glasses should be overcorrected.

Some people may not have accurate optometry and may not be able to detect astigmatism, so they try to increase their myopia, which can improve clarity but is overcorrected. The reason for being able to see is through the adjustment of the eyes themselves.

It is not difficult to determine whether one is nearsighted or overcorrected, and a red-green visual acuity test can be performed. Did you perform a red and green visual inspection during your optometry? If not, and the new discountglasses look clear but uncomfortable, they may be overcorrected.

If you want the inspection of the red and green visual targets to be accurate, it is best to project red and green light with a polarizing plate or mode box (which is the uniform red and green light), and such red and green light is the effective inspection. A professional examination environment is crucial for the accuracy of optometry.

However, there is a situation that needs to be adapted to: changes in the degree of the new and old glasses, low degree of the old glasses, and the eyes being relaxed for a long time when looking close, while the new discount prescription glasses will exert normal force when looking close.

So changing to new glasses may cause a brief blurry and tiring close-up, which is normal and requires adaptation, and it will gradually improve. This is not the case. The glasses are clear but uncomfortable. Don't adapt, we need to adjust the glasses.
