How to view temple information? Generally, temple sizes are labeled with frame dimensions, with width being particularly important in determining whether the size of the cheapest eyeglasses online is appropriate.

Glasses are a standard product on eyeglass mart, with parameters indicating the size of the glasses on the legs, nose bridge, or label.

It is recommended to find out the size of the frame that suits oneself through the following methods: check the parameters of the glasses that have been equipped (usually marked on the inside of the temple); Measure the equipped glasses with a ruler to obtain approximate data; Try on and note down the size that suits you.

The center thickness, refractive index, curvature, and thickness of myopic lenses are the same. In theory, the smaller the diameter, the thinner the farsightedness/presbyopia lenses. Therefore, if possible, the smaller the lens diameter, the better.

But lenses do not exist independently, they need to be matched with frames to create suitable glasses for wearing. This involves the question of whether the diameter size can achieve the actual distance between the customer's pupils.

When fitting for farsightedness/presbyopia, it is often necessary to consider, that the eyes close to the human eye require internal rotation, resulting in a smaller distance between the near and far pupils.

The smaller the diameter, the thinner the lens, especially for high-farsightedness/presbyopia glasses. Choosing a more suitable frame allows for a smaller diameter, resulting in thinner and lighter lenses.

Even if a low refractive index lens is chosen, as long as the diameter is small enough, it is still relatively thin and light. Since the lenses have already been selected, the only solution is to customize the lenses, make larger lens diameters, or do a center shift.
