What is the weight and thickness tolerance range of the lens? I just can't remember it all day wearing it. I really can't give you a standard degree range for this, because everyone's pupil distance is different and the discount prescription glasses frame size chosen is also different.

Everyone has different levels of sensitivity to the weight of eyeglasses online, for example, they can wear glass lenses for half a year, but if the resin lenses just turn a little yellow, they won't be able to handle it.

When you need to consider this issue, you must have at least one pair of glasses, and based on this, estimate your tolerance.

What does it mean to not feel dizzy? There will be distortion at the edge of the lens! The higher the degree, the more obvious the prism effect, which can cause dizziness! If the degree is too high, the visible range will be very small, so small that it cannot be used as work eyeglasses!

Why is it said to be the most correct choice? It all depends on other materials to complement it. Simply put books that are thinner than it are not as good, while those that are better have defects. The price is cheap and the quantity is sufficient, so there is no need to ask which one is better than it.

Functional glasses, also known as the second pair of glasses (up to the Nth pair of glasses), include anti-blue light, anti-UV, accessory glasses, and so on. Finally, there is the purchasing channel. For example, if you plan to shop for the cheapest eyeglasses online, the general rule is that the more money you save, the higher your knowledge requirements will be.
