For long term glasses wearers, why do they still need to go to the optician’s?

Those who are wearing correctional glasses often neglect the fact that they need to go to the optician’s regularly. According to the specifications and requirements, glasses wearers, especially teenagers and middle and old age glasses wearers who are over 40 years old, should get optometry on a regular basis.
First of all, let’s start with teenagers. Teenagers are still at the age of puberty so the refraction of eyes is still changing continuously. This process presents a kind of trend which the positive diopter is gradually decreasing while the negative diopter continuously increasing.

Perhaps this time the degree of glasses that have been through the optometry is very accurate, however, after a period, as the refraction of eyes changes, overcorrection will appear in presbyopic cases while under-correction in myopic cases. Neither of these two cases will do any good to the correction of eyes.

In order to correct ametropia, the changes of the refraction of eyes should go through dynamic monitoring, which can be realized by going to the optometrist regularly.

Now let’s move on to the middle and old age glasses wearers who are over 40 years old. The accommodation strength of their eyes will decline physically because of the age. This decline will have greater influence especially on people between 40 to 50 years old and those who read a lot.

Therefore in order to keep a good mood and status both in life and work, it is very necessary to wear proper myopia glasses. However, myopia glasses should be changed as the accommodation strength of eyes are declining continuously. Thus regular optometry is essential to get a new pair of proper glasses.


Overall, teenager and middle and old age glasses wearers should go through optometry regularly. However, how often should one go to the optician’s? offers the following advice to glasses wearers according to the pattern of physical changes of human body:

1. Teenager glasses wearers: once a year.

2. People who are over 40 years old: every two years

3. People who are 25 to 40 years old: the interval can be longer, every three years is fine.

Above three is the general rules of regular optometry for glasses wearers.

It’s of great benefit to observe the dynamic changes of our eyes’ refraction status. Meanwhile, it provides an important reference to the correction of ametropia and the upgrading of proper glasses.
