Let's start by answering the question: how long has it been since you changed your glasses?
The amount of myopia in adults usually doesn't change much, and many people may wear one pair of glasses until the end of time ......
In fact, this is wrong ！！！！！
Eyeglasses also have a shelf life. If you don't have any special care, you should consider replacing the glasses you wear frequently on a daily basis for 1 to 2 years.
If your world is getting blurry, dark and your eyes are uncomfortable, it's likely that your glasses have 'expired'.
In the course of daily wear, "blurred lenses" or even "worn out lenses" may occur due to improper wear or other factors. Some myopia patients think that "it's just a little blockage of vision, it doesn't matter much", and they don't think it's a big deal.
In fact, "blurred lenses" and "worn lenses" not only make vision unclear, but also fatigue the eyes after wearing for a long time, and even deepen the development of myopia!
What are the effects of blurry spectacle lenses on vision?
✖ Scratches affect vision and may cause visual fatigue in the long term
Lenses are not wear-resistant and become susceptible to scratches during daily use. The ciliary muscle of the eye needs to adjust constantly to try to change the state of blurred vision for objects that cannot be seen clearly. If you can't get relaxation for a long time, it is easy to aggravate eye fatigue, and it will be more difficult to see things.
✖ Affects aesthetics
Scarred lenses not only affect the health of your eyesight, but also your image.
✖ Frequent replacement and cost increase
If your lenses become scratched and worn out, affecting your life, work and studies, you will have to replace them with new lenses. Frequent replacement is not only costly, but also a waste of time.
What are the causes of damaged and blurred lenses?
✖ Poor quality of the lenses
Whether your lenses are easily scratched or not has a lot to do with the quality of your lenses. Nowadays, lenses are coated, so the better the quality of the film layer, the less likely the lenses are to be spent.
✖ Casually placing glasses
Taking off your glasses casually and placing them on the table might cause the lenses to come into contact with the table and create a scratch.
✖ Lens cleaning
Some people may feel that the lens is too dirty or in order to achieve the purpose of "disinfection", used to go to the alcohol wipe lenses, in fact, this method is not desirable, the film layer of the lens is likely to be corroded, resulting in the lens off the film.
✖ High-temperature water cleaning lenses
Don't use high temperature bath water to wash glasses, especially when taking a bath, the lens coating layer is very afraid of high temperature, don't want to scrap the lens, don't try!
How to clean your lenses correctly?
✔ Cleaning lenses correctly
Firstly, rinse with normal temperature water to flush out the small particles attached to the surface, and then use a mirror cloth to absorb the water in one direction. If there is oil, dilute the detergent a little and evenly wipe it onto the lenses, then rinse and vacuum.
If the frames are metal, take care to wipe the frames as well to avoid rust.
✔ Wipe the lenses properly
Wrong treatment such as clothes corner wiping glasses, napkin wiping glasses ...... will lead to wear and tear on the lenses that is not visible to the naked eye, and the lint from the napkin will stick to the lenses, leading to blurring of the lenses.

If the lenses have obvious wear and tear, it is recommended to replace the lenses.
