Is it good to wear contact lenses

Children nowadays become nearsighted since primary school. They are so young, but still wear glasses, which looks particularly funny. So people invented contact lenses. Contact lenses are worn inside the eyes and cannot be seen from the outside. You may think that someone's eyes are normal, but they may also wear contact lenses in their eyes. But is it good to wear contact lenses?

Some people may ask, will contact lenses melt at high temperatures? Can they be worn for a long time? Are there positive and negative contact lenses? Will wearing contact lenses for a long time be harmful to the eyes? Today, through the introduction of this article, you will know everything you want to know, and I hope it can help you next time you buy glasses.

advantage:

1. Real images: Frame glasses can magnify or reduce images more effectively than contact lenses, especially for people with high refractive errors. In other words, the images seen with contact lenses are close to reality. 2. Clear vision: Frame glasses can block part of the field of vision, and the highly concave and convex lenses will act as a prism around them. 3. Comfort: It eliminates the pressure of frame glasses on the bridge of the nose, the friction on the auricle, and the allergy of the frame. 4. Convenience: Especially for actors and athletes, there is no need to worry about breaking their glasses. Fog occurs when the temperature changes rapidly. When you wear contact lenses on rainy days, the lenses will not get wet. 5. Beautiful: Show the natural beauty of the wearer. For example, patients with high myopia can avoid the unsightly appearance caused by the bottle-like lenses of frame glasses. 6. Large refractive errors are difficult to correct with frame glasses, especially for those with high monocular refractive errors. For example, after monocular cataract removal surgery, the only way to correct it is to wear contact lenses.

Contact lenses are attached to the cornea, and various problems may arise during use. Therefore, many ophthalmologists are conservative about the promotion of contact lenses. The problems are roughly as follows:

1. A foreign body sensation may occur when you wear the lens for the first time, do not maintain it properly, or have an eye disease. 2. Improper fitting or improper use may cause corneal damage. 3. Suitable for people with dry eyes and excessive eye discharge. 4. It is not suitable for workers working in bad environment, windy and sandy environment, or in the workplace with volatile acids and alkalis, lots of oil smoke and dust. 5. Practice before wearing glasses. In short, different people have different opinions. Whether to wear contact lenses or frame glasses depends on what you care more about.

The above is a detailed analysis of the advantages and disadvantages of contact lenses, but my personal suggestion is that although contact lenses are very convenient, they also have many disadvantages. The eyes are a particularly fragile organ and cannot withstand even the slightest stimulation. So just in case, it is recommended that you put safety first. If you must wear contact lenses, please be sure to pay attention to safety.
