How long can the effect of Xi'an ophthalmology glasses last?
Ophthalmology is a treatment process to improve vision. For people who use glasses to correct vision problems, they may want to know how long this effect can last. As an advanced city of ophthalmic medicine in China, Xi'an also has many advanced hospitals in the field of ophthalmic glasses. This article will elaborate the effect duration of Xi'an Ophthalmology from four aspects: corneal shaping lens, contact lens, corneal refractive surgery and glasses.
Keratoscope
Corneal shaping lens is a special contact lens for night wear, which can correct myopia by shaping the corneal surface. Clear vision can be obtained without using lenses in the daytime by using corneal shaping lenses. The effect of this lens can usually last for one to two days, but the specific duration will vary from person to person. Some people may begin to feel fuzzy after a few hours, while others may continue throughout the day. In order to maintain the best visual correction effect, it is necessary to wear corneal shaping glasses every day.
For those who want to obtain long-term vision correction, the corneal plastic lens may not be the best choice. However, it is a good choice for those who are not suitable for surgery or who only need short-term vision correction.
contact lenses
Contact lenses are a common vision correction method, which can be used to correct myopia, hyperopia and astigmatism. The duration of contact lenses depends on factors such as the type of lenses used and personal lifestyle. Generally speaking, the effective use time of contact lenses is one day. Use new contact lenses every day to help maintain clear vision and reduce the risk of eye infection.
However, some people use monthly or annual contact lenses, which can be worn for a longer time according to the user's lifestyle. These lenses need regular cleaning and maintenance to ensure their normal use and extend their service life. No matter what type of contact lenses you use, you should go to an eye hospital for regular inspection to ensure the health of your eyes and the stability of your vision.
keratorefractive surgery
Corneal refractive surgery is a kind of surgery to correct vision problems by changing the shape of the cornea with laser technology. There are some well-known ophthalmic hospitals in Xi'an that provide this operation. The effect of vision correction can last for a long time, even permanent.
However, the effect of corneal refractive surgery is still affected by some factors, such as age, corneal stability and postoperative care. Before receiving corneal refractive surgery, the doctor will conduct a detailed examination and evaluation to determine whether the surgery is suitable for the patient, and explain the effect and risk of the surgery.
glasses
Glasses are one of the most common vision correction methods. By wearing appropriate glasses, vision problems such as myopia, hyperopia and astigmatism can be corrected in real time. The effect of glasses is immediate. As long as you wear glasses, you can immediately get clear vision.
The duration of glasses mainly depends on the care and use of glasses. Regular cleaning and maintenance of glasses to avoid excessive wear and accidental damage can extend the service life of glasses. After glasses have been used for a long time, they may also need to be re equipped to correct vision changes.
Summary
Xi'an Eye Hospital provides a variety of vision correction methods, such as corneal plastic lenses, contact lenses, corneal refractive surgery and glasses. Different lens matching methods will have different effect duration. Corneal plastic lenses and contact lenses need to be replaced every day or at regular intervals, and the effect of corneal refractive surgery may be permanent. Glasses can be worn and replaced at any time as required. Personal living habits, corneal stability, postoperative care and other factors will also affect the duration of the effect. Therefore, when selecting ophthalmic lens matching methods, patients should make appropriate choices according to their own needs and the doctor's suggestions.
