Many people may think that the so-called medical optometry is nothing more than testing the degree of myopia in the eyes, and using this result to go discount eyeglasses online for glasses fitting, which is much cheaper!

Hey, this guy, I want to tell you that an optometry prescription is a measurement of the refractive state of the eye, but it is not an exclusive prescription for your glasses.

For example, if a tailor needs to measure the leg length before making pants, but before making pants, the tailor will ask about your personal preferences. Some people want the legs to be shorter, exposing the ankles, while others want the pants to be longer, covering the upper. This requires personalized correction based on accurate measurement of customer leg length and customer requirements.

Wearing discountglasses is the same. The result of optometry is like a customer's leg length, but the prescription for glasses is a conclusion made by the optometrist and optometrist based on the customer's usage, age, occupation, and other information, or can be understood as a "life prescription".

I saw an example of the cheapest eyeglasses online, where a customer's optometry sheet was correct and their glasses matched perfectly with the sheet, saying "I can't see clearly.". Later on, it was discovered that this customer was a meteorologist and his work environment was very complex: sometimes he needed to see the numbers clearly on a meter-high instrument panel; Sometimes he had to see the data on the statement that was only half the size of the ID card number.

Finally, the optometrist gave the customer three prescriptions, one specifically for seeing far, one specifically for seeing close, and one for wearing normally. Therefore, optometry and glasses matching are a complete task, and if done separately, it is easy to encounter problems.
