What should I do if my old glasses slide down? The use of anti-slip glass covers is a "magic weapon" specifically designed to prevent glasses from slipping off, making discount prescription glasses not only more beautiful and stable to wear, but also more effective for outdoor sports.

Using anti-slip nose pads, attached to the integrated nose pad, effectively raises the nose pad, reduces the distance between the noses, and prevents the glasses from slipping down; (discountglasses with nose pads can be worn more securely by adjusting the position of the nose pads.).

Using tape or cling film, wrap two circles of tape around the nose bridge of the frame and the curved parts of the legs and ears of the mirror. This method is more convenient and effective.

I have changed to a new pair of glasses and it appears that my vision is distorted. First, I need to check if the prescription for glasses is correct. Usually, if the degree is too high, which is what we call overcorrection, it may cause the straight line to bend.

When prescribing cheap eyeglasses near me, in addition to the degree and axial position of myopia, hyperopia, and astigmatism that are familiar to everyone, attention should also be paid to the indicator of pupillary distance.

Pupil distance refers to the distance between two pupils. When a normal person's eyes are looking at an object, they will form separate images on the retinas of both eyes and then the brain processes these two images to merge them into a complete, three-dimensional object, which is also called binocular monocular function.

The accuracy of pupillary distance measurement will affect the accuracy of prescription glasses. Especially for people with higher degrees, have higher requirements for the accuracy of pupil distance. Once there is a deviation, the prism effect of the lens will make the glasses very unsuitable.
