The cliff-like cooling is coming, are everyone's ok mirrors okay?How many people are experiencing the pain of "fragments"?
Broken when taking off the lens, broken when cleaning, broken when falling on the ground, broken inexplicably, broken ...... inexplicablyIt also broke people's hearts to the ground......
So, why is there a high incidence of debris in winter?How can debris be avoided?After reading this article, you will get the answer!
Why is there a high incidence of debris in winter?
In normal times, the OK mirror is not as fragile as everyone thinks. Some lenses can even be pinched and folded in half close to 90 degrees, all intact.
In order to satisfy everyone's curiosity, I specially tested it for everyone:
Dangerous behavior, don't imitate!
Why does such a "tenacious" ok mirror become collectively "fragile" in winter?There are mainly the following reasons:
Low temperatures
Friends in the north may be more sympathetic. Outdoor drainage pipes that are good on weekdays are especially easy to break in winter. This is because the temperature is low in winter, which can easily cause the toughness of the object to weaken and increase the brittleness. This will lead to the risk of breakage**. In addition to the ambient temperature, the temperature of the hand and the temperature of the care solution will affect the lenses.
Uneven force
This is more common when rubbing the lenses or taking the lens from the suction stick. Due to the unskilled kneading technique, or the fingers are frozen, the force is deep and shallow.
When taking the lens from the suction stick, pulling on the lens increases the risk of fragmentation.
Rub gently to avoid scratching the lens with your fingernails.
Lens scratches
In the process of daily care, nail scratching, rough fingers, improper rubbing, etc., will cause the surface of the lens to be covered with scratches of different shades, and when subjected to external force, the deeper scratches will be more likely to break.
How should debris be prevented in winter?
Pay attention to the temperature
Pay attention to the temperature of your hands. Wash your hands with warm water before putting them on to avoid debris caused by stiff fingers and "too much force".
Pay attention to the storage temperature of the care solution. It is recommended to store the care products in an environment of 10-20 degrees Celsius to avoid freezing the care solution and cracking the lenses due to the low temperature.
Pay attention to the storage temperature of the lensesIt is not recommended to carry lenses outside in winter, and keeping them indoors can also avoid the occurrence of fragments.
Pay attention to the force
In this step, just remember"Don't pull hard".Can. This is especially true for those who use the suction stick to remove the lens.
When removing the lens from the suction stick, move the suction stick smoothly away from the horizontal direction of the lens and avoid pulling it straight up and down.
Pay attention to the method of care
First of all, you should build your nails regularly to avoid them being too long and sharp. At the same time, when rubbing the lenses, it is recommended to pay attention to the amount of care solution, and it is recommended to put at least 3-5 drops of care solution on the concave surface of the lens to ensure that the lens is completely moistened before rubbing the lens.
The lubricant added to the multi-purpose care solution can lubricate the lens well and effectively reduce the occurrence of lens scratches
Of course, in addition to these precautions, the material design of the lens itself is also the ultimate indicator of "shatter resistance". Menicon Z Night is made of ZOMA materialWhile ensuring the high oxygen permeability of 163, it also has good lens strength (which can be popularly understood as "shatter resistance").。Comply with the relevant requirements of international ISO and Chinese regulatory agencies to ensure the safe use of lenses.
The high incidence of debris in winter, I hope everyone can easily grasp the essentials of "shatterproof", so that the lenses are safe!
