When it comes to getting glasses, many people are probably experienced, as myopia has become an important phenomenon among contemporary people on eyeglass mart.

I believe most people's opinions on matching glasses mainly focus on several aspects: which eyewear store to choose? Is it okay to pair eyeglasses online cheap? Which lens is better? Of course, this also includes the choice of frame glasses.

However, today we are going to talk about an easily overlooked issue, which is optometry. When it comes to optometry, many people probably think that it's not a very simple thing, so many people think that it's just a process, everyone has it, just focus on the lens related matters.

In fact, this is a very common misconception in glasses fitting. Compared to lenses, optometry may be more worthy of attention. The important purpose of optometry is to determine the optical parameters of the eye and provide reference suggestions for myopia correction and prevention.

It can be said that optometry is the most important step in fitting discount prescription glasses, providing basic information for the next glasses fitting. If this foundation is not established properly, it may not only lead to inappropriate lenses, but also cause more problems due to neglecting eye health issues.

I believe everyone knows that the main reason for myopia is that the crystalline lens of the eye has deformed, causing our vision to not fall correctly in the designated position. This is commonly known as axial myopia, which is usually corrected through lenses.

However, myopia is not just that simple. Apart from axial myopia, there are other types of myopia. Refraction refers to the myopia caused by changes in refractive factors, where the crystalline lens cannot accurately land in the position of the retina.
