Recently, as the number of people who use glasses and contact lenses together or wear circle lenses to look stylish is increasing, contact lens brands have begun to raise prices. Even if you paid a lot of money to purchase contact lenses, you must know how to use them correctly to prevent eye diseases such as cornea damage.

According to the Ministry of Food and Drug Safety on the 26th, a contact lens is a medical device worn directly on the eye and used for the main purpose of correcting vision in cases of myopia or hyperopia.

This includes not only vision correction but also colored contact lenses. Depending on the material, they can be divided into ‘hard contact lenses’ and ‘soft contact lenses’. Hard contact lenses are made of hard materials that cannot absorb moisture, such as glass and acrylic resin, while soft contact lenses are made of soft materials with high moisture content, such as hydrogel (hydrophilic polymer) and silicone hydrogel.

Depending on the purpose of use, contact lenses are classified into vision correction, treatment, and cosmetic purposes (circle lenses). Depending on the usage time, they are divided into daily wear lenses, which are worn only during active periods, and continuous wear lenses, which are worn for more than 1 day, including sleeping time.

The International Organization for Standardization (ISO) sets testing standards for physical and chemical performance and biological safety required for contact lenses. The Ministry of Food and Drug Safety also defines hard contact lenses and soft contact lenses in the ‘medical device standard standard’, which is equivalent to the ISO standard, and is reviewing each item for approval.

In order to use contact lenses in a healthy way, get an accurate examination of your eye health with a doctor or other specialist at an ophthalmology clinic before purchasing them. Also, when purchasing, you should consider the purpose of wearing, wearing time, living environment, etc. During use, clean and maintain thoroughly with a cleaning solution specifically designed for contact lenses, and do not reuse disposable products.

It is essential to clean contact lenses before and after wearing them. Add 2-3 drops of dedicated cleaning solution and gently rub to clean. Replace the lens case at least once every three months. The case is cleaned daily and completely air-dried with the lid open.

Be sure to check the expiration date of your lens care solution. Saline solution without preservatives is prone to bacterial growth, so use it within one week after opening.

Also, it is best not to wear contact lenses for too long. When worn for a long time, the cornea may swell due to insufficient oxygen supply to the cornea, and it is prone to bacterial infection or wounds.

Lenses should not be used interchangeably. Bacterial infections can cause various eye diseases such as corneal damage and eye ulcers. Due to the risk of various bacterial infections, you should not wear it while playing in the water.

The material of soft contact lenses is soft and easy to tear, and products with low oxygen permeability can cause redness and corneal edema when worn for a long period of time, and the moisture absorption characteristics of the contact lenses themselves can cause dry eyes.

Additionally, when engaging in water sports such as swimming, the risk of bacterial infection due to external contaminated water may increase.

Hard contact lenses require time to get used to because they have a higher foreign body sensation compared to soft contact lenses, but once you get used to them, you can feel comfortable even if you wear them for a long time. In general, tear circulation and oxygen supply are better than soft contact lenses, so there is less chance of developing corneal or conjunctival diseases. However, caution is required as there is a risk of contact lenses falling off or being lost when exercising.
