How to use contact lens correctly?
Method of wearing the contact lens
Wash your hands before putting on contact lenses, and be careful not to leave long nails, to avoid contamination of the lens by bacteria and nail scratches. Place the contact lens on the tip of your index finger, face-up, and pull your upper and lower eyelids apart with the middle fingers of both hands. Look straight ahead and place the lens gently into the eye (attached to the cornea). Remove the index finger and look down so that the lens is attached to the cornea, and slowly relax the eyelids with the middle fingers of both hands. Blink gently several times (or roll your eyes) to remove bubbles.

Look up, open the upper and lower eyelids with the left index finger and right middle finger.

You can use the index finger first to move the lens down, and then gently pinch the middle and lower edge of the lens with the thumb and index finger belly, and take off the lens.
A periodic review is necessary.
In the process of wearing contact lenses, the eyes may change due to the existence of contact lenses. At the same time, in the process of wearing contact lenses, the lens may be polluted, damaged, and have other changes. This is to check regularly to prevent damage to the eyes. Usually, the recommended review period is one week, one month, three months, half a year, and once every half a year after wearing it.
Check your eyes for abnormal cases.
Do your eyes sting or dry? If so, it is recommended not to wear contact lenses for the time being. Look in the mirror to see both eyes carefully, if it is red and swollen or if is both eyes full of bloodshot? If you do, you can no longer wear contact lenses, and you can go to a professional store for inspection. After putting on the contact lenses, block the left and right eyes respectively to see if the vision of one eye is clear. If the eye vision has decreased or blurred, check if the lens is dirty. If the lens is still the same, you should go to a professional store to find out the reason.
It is not recommended to use contact lenses when they are dry. Because when they are dry, even the nursing vacuole is used, the parameters change. It will affect the comfort of wearing, so it is recommended to replace the new lens. After the nursing liquid is used every time, you should cover the lid tightly. Do not touch the mouth of the bottle with your hand. If expired and unused, it should be discarded and replaced with new nursing fluid. As for your discomfort, you should return to the store for inspection.Contact lenses and glasses should be used interchangeably.
