How To Wear Contact Lenses? Don't Let Your Eyes ’have Been Stunned’

- Jul 01, 2019-

Everyone who wears the frame glasses knows the pain. Although the world is clear, the bridge of the nose begins to hurt. The rain lens is destroyed. I want to do sports. I am afraid that the glasses will fly in the middle. In winter, when I enter the room from the outside, I will be blurred. ... contact lenses solve all the above problems. A contact lens is a thin lens that is placed directly on the surface of the eye and can be used to correct vision. In 2004, about 125 million people worldwide used contact lenses. By 2010, the average age of people wearing contact lenses was 31 years old, and two-thirds of them were women.

According to different standards, there are many types of contact lenses. According to the different materials of glasses, they can be divided into soft and hard:


Soft contact lenses are made of flexible plastic that allow oxygen to pass through the cornea. This type of contact lens will have a specific replacement cycle, such as daily throwing, monthly throwing, half-year throwing, and annual throwing.


Hard contact lenses, which are more durable, resistant to deposition, are easier to handle, and are less prone to tearing.

Long-wearing type can be soft or hard. After each removal, you should rest at least one night without wearing contact lenses, otherwise it will cause eye damage.


Single-shot, a disposable contact lens, "one-time" refers to single use and disposal, as defined by the FDA. The “Daily Wear” (DW) contact lens was originally designed to be worn for a day and then removed before bedtime. Disposable contact lenses are useful for people who don't wear contact lenses often, or when it's possible or difficult to change contact lenses, such as on vacation.


Wearing contact lenses corrects vision and helps correct focus by correcting ametropia for a clearer vision.


Spherical contact lenses bend the light evenly in all directions (horizontal, vertical, etc.), and such glasses are often used to correct myopia and hyperopia.


The horizontal focus force of the vertical contact lens is different from the vertical focus force, so the astigmatism can be corrected. Some spherical rigid lenses can also correct astigmatism.


The beauty we often refer to is classified as a decorative contact lens in the United States and does not have corrective function. However, like other contact lenses, beauty may also cause complications, including eye irritation, redness, and infection.


Some of the beauty is just to color the iris, highlight the natural color of the iris, and some will completely cover the iris, greatly changing the color of the eye.
