Nowadays, most people find it very cheap and convenient to buy glasses online. But did you know that choosing a suitable frame is more crucial than selecting lenses? Even if you buy expensive lenses, frames that don’t fit are a waste of money.

About the recommended choice of glasses size, I believe we have seen many people have done the relevant strategy. Choose the one with or without nosepieces; choose metal glasses or plate glasses. 

But the most crucial thing is not mentioned in most guides. That is the pupil height. Pupil height is the vertical distance from the lower edge of your glasses to the centre of your pupil. Most merchants will set the pupil height at the centre of the lens by default. Those who buy online will need to choose their frame styles carefully.

Is pupil height that important? The answer is yes. Pupil height is essential. An accurate pupil height ensures that your vision stays in the centre of the lens, and the centre of the lens is where your prescription is. If you are out of the centre of the lens, then the prescription will be inaccurate. If you wear your glasses in a low or high position for a long time, you will experience vision fatigue.

So how do you get your eyes to always look out of the centre of the lenses? The answer is to choose the right frame. Choose the appropriate bridge to ensure that the glasses on the bridge of the nose will not easily slide off and the height is accurate. Choose the right length of the temples and width of the frame to ensure that the glasses do not slip forward. Make the glasses as light as possible so they don’t slide down due to weight. If the glasses are without a nose rest, you must choose the correct width of the nose bridge. Too wide will make the glasses position low.
