1. Hydrogel: ordinary material, cheap, less comfortable. People who think their eyes are healthy can try it, but it is not recommended.

2. Silicone hydrogel: It has high moisturizing properties and is suitable for people with dry eyes, but the lenses are relatively thick and are not suitable for sensitive eyes or those who seek high comfort.

3. Non-ionic: The most comfortable. The lenses are thinner and softer because of the addition of non-ionic, and are not easy to precipitate protein. It is highly recommended for fairies who pursue comfort. Of course, the price is relatively high.

1. Start wearing from the right eye: The problem of not being able to wear contact lenses often occurs among beginners. It is recommended that beginners start wearing contact lenses from the right eye when wearing them for the first time. People usually use their right hand more, which makes it more convenient to wear them. Also, starting from the right eye will not easily cause confusion about the degree.

2. Try to use your fingers when wearing them for the first time: You can use your fingers or contact lens sticks to wear contact lenses, but it is recommended that people who are wearing contact lenses for the first time or who cannot wear contact lenses should choose to use their fingers. After all, fingers are your own body organs and they are easier to operate. Contact lens sticks are relatively complicated to use and can easily cause the contact lenses to flip in direction, making them more difficult to wear into the eyes.

3. Carefully confirm the front and back of the contact lenses: Before wearing them, carefully confirm the front and back of the contact lenses. If the direction is wrong, it is very likely that you will not be able to wear them. The specific way to distinguish them is to use tweezers to clamp the contact lenses on your fingers and observe their shape. If they are like a round bowl, it means they are on the front. On the contrary, if the shape of the contact lenses is like a plate with the opening on top opening to all sides, it means they are on the back.
