Water content: the moisture content of contact lenses. Because contact lenses can be made directly into the eyes, they must contain moisture to make contact lenses moisturized and accessible without irritation. Usually, contact lenses that contain more than 50% moisture are called contact lenses that have a high moisture content and contact lenses that contain less than 50% moisture are called low water content. The moisture content of contact lenses is related to how long they can keep your eyes comfortable. Therefore, water content is essential to finding contact lenses that fit you.
Then, Is it good contact lenses when the number of water content in contact lenses is high?
Not exactly. A high number of water content may or may not suit you. There are several variables when you choose a contact lens (base curve, contact lens diameter, oxygen permeability, water content, etc.) but water content determines how long the contact lens will stay in your eyes without any discomfort. The high water content of contact lenses means that they want to stay moist. Because contact lenses contain a lot of water, they are also good for wearing. But in other words, it also means that it takes a lot of water from the eye. Therefore, the higher the moisture content, the better the initial feeling of use of the eyes and the less inconvenience at the beginning of use.
Instead, people who lack tears get dry faster when they use it for a long time. Appropriate use time for contact lenses with high water content counts is about 8 hours. Conversely, contact lenses with low water content may be slightly uncomfortable to initial wear, but they may be less dry to wear for longer periods of time because they take away less moisture from the eyes during prolonged use. However, it is not absolute because it can be caused by the thickness of the contact lens, the fitting condition of the contact lens’ eyes, and the material of the contact lens.
Which contact lenses are high in water content?
Daily contact lenses usually have a high number of water content, and Bi-weekly or Monthly contact lenses have low water content. As mentioned above, low water content numbers can take away less moisture from the eyes, which can be worn longer, and have a cost advantage. However, contact lenses that are used for more than two weeks can be thicker and more uncomfortable to wear than Daily contact lenses. I recommend daily contact lenses to be replaced as much as possible because they can cause cornea deformation in the event of side effects (although the variables will vary from person to person).

Contact lenses are an innovative medical device that allows people who cannot see clearly without glasses to see clearly and clearly without glasses. Let’s see how this very thin medical device can be used more safely. In this article, we will learn about “10 Things you need to know about using contact lenses.” I’m writing to tell people who are currently using contact lenses or who will be using contact lenses in the future. The person who is writing this is an optician of Korea. I also have been using contact lenses for more than 10 years. Now, I’m going to tell you that my experience and my knowledge as an eye health expert have come out. So let’s get started.
1. Always use contact lenses in a clean environment.
Make a clean environment before using contact lenses. Wash your hands clean and wipe with a clean wet towel first, then use contact lenses while your hands are dry. As with contact lenses, always keep your hands clean when removing contact lenses also. If contact lenses are worn and removed using other tools, they should also be clean and disinfected periodically. And if you keep using contact lens cases without disinfection, you’re exposed to harmful bacteria. This can cause secondary infections as a result of microscopic corneal wounds in the eye. Always keep the contact lens case clean and replace it with a new one if it is badly contaminated. Cleanliness for the health of the eyes is not enough to be emphasized 100 times. Make sure to use contact lenses in a clean environment.
2. If you feel any abnormality with the contact lens, remove it immediately.
Contact lens wearers may have experienced once the discomfort of dust from the contact lenses when they enter your eyes together. Then remove the contact lens from the eye, remove the dust with lens preservative, and try again to avoid discomfort. However, if you continue to feel uncomfortable when wearing contact lenses, you should remove them immediately to prevent other damage. Occasionally, contact lenses may have been slightly distorted by long fingernails and damaged, or contact lenses from the product process may be defective. In such cases, remove the lens immediately to protect your eyes. If you keep wearing it, it can damage your cornea.
3. Restrict usage time – It is recommended to wear it within 8 hours.
While you wear contact lenses, contact lenses are on the surface of your eyes. Whenever you blink, the cells in the outermost cornea cause friction with Restrict usage time – It is recommended to wear it within 8 hours. the contact lenses. If tears that act as a lubricant to the eyes are not secreted properly, it can also cause cornea injury. Sometimes your eyes will feel uncomfortable if you are in a situation where your eyes are short of tears and if it persists, it can hurt your cornea. This can cause inflammation of the eyes, so it is recommended that you select contact lenses to suit your situation and limit your use time. We recommend that you wear it within 8 hours. (The specification of contact lenses that can affect usage time is the water content.)
4. Use only contact lens preservative solution for the preservation of contact lenses.
From the moment you wear contact lenses, there can be various harmful bacteria and other sediments such as protein. If you don’t take care of them, they can cause complications. If you keep your contact lenses in tap water, saline, etc. on a temporary basis, your eyes can be exposed to serious danger.
The contact lenses must be preserved in a contact lens preservation solution. Preserved contact lenses can be contaminated if they are preserved in the preservative for a long time. Contaminated lenses should be discarded because they can cause eye problems. If you want long-term retention, you must replace the contact lens preservative at least once every three days. And it’s a very dangerous idea if you think a contact lens preservative is available for long periods of time.
All contact lens preservatives must be exhausted within one month of release. The contact lens retention solution is not available for long periods of time as germs breed in the contact lens retention solution after opening. As a result, it can cause secondary infections in the eyes. So you don’t have to buy too much contact lens retention per unit.
5. Avoid direct contact water with the eyes when wearing contact lenses.
Contact lens users live their daily lives in contact lenses. So when you wash your face or swim in particular, water comes directly into your eyes. Attention is required at this time. Our eyes have a tear circulation. Moisturizing material is released from the eyes and acts as a moisturizer.
If you think about this role, you’ll see that when the water hits the eye directly, it’s washed away to the moisturizing layer of the eye. Friction can damage the cornea as the eyes become very dry at the moment. The habit of removing contact lenses especially after washing is not good.
If you attempt to forcibly remove contact lenses that do not fall from the eye, there may be serious damage to the cornea. Remove the lens and wash your face before washing And if you swim in contact lenses, it can cause eye disease. In a swimming pool, water is almost inevitably in contact with contact lenses, and the water in the pool is likely to be contaminated as well Don’t use water glasses or contact lenses in the pool.
6. Avoid cheap contact lenses and low-cost color contacts.
Through social networks and websites, many people are selling low-cost contact lenses. It’s easy to get and it’s cheap, so it’s usually easy for younger consumers to buy. But this requires attention because it can bring great disaster to your eyes, regardless of your age. As opticians responsible for the health of people’s eyes, we tell people never to buy cheap contact lenses.
The reason is that the quality or material of the product is absolutely not good. The normal contact lens manufacturing process (especially in Korea) has been subjected to very difficult inspection criteria, completing a clean and safe product within an automated manufacturing process. In the process, bad or good products are classified and only the best products are provided to the customer. The loss in the process makes the price slightly higher, but it can maintain good quality. However, cheaper contact lenses from China can be very simple or even non-existent in the inspection process. Usually made of low-cost materials with low oxygen penetration.
Especially for low-cost color contact lenses, bad dye contact with the eyes can cause allergies or cornea injuries, and secondary infections can lead to necrosis and maximum blindness. So we’re setting the bar and arguing that absolutely these very cheap, very harmful products should be taken out of the market.
All color contact lenses sold at Pixel-eye.com are made from FDA approved ingredients and are sold exclusively through rigorous quality inspection. These are products that have improved wear and safety by using a sandwich technique so that the dye will never come into contact with the eyes. Your eyes are always precious. Don’t use contact lenses that are too cheap.
7. Select the contact lenses that suit you.
The availability of contact lenses and eye discomfort are closely related to water content. (What is the water content of contact lenses?) I’ll give you an example of two products from a company. In this chapter, we will talk about water content that affects the feeling of wearing. Let’s compare Clalen iris Bi-weekly contacts and Clalen iris Daily contacts from Clalen, a leading Korean contact lens brand. Which people should use Bi-weekly between these two products and which people should use daily products?
Clalen iris Bi-weekly products have lower water content than Clalen iris Daily products. Contact lenses with low water content may not feel good for the first time, but as time goes by, eye moisture is not taken away and can be used for a little longer. Daily contact lenses, on the other hand, contain a lot of moisture and are good for first-time use in moist conditions. However, the moisture in the eyes decreases as time goes by because it takes away more water from the eyes.
If you find a product that has a moisturizing and good feeling within 8 hours, recommend Daily products with high water content, whereas if you want to use a longer contact lens, recommend a Bi-weekly contact lens or Monthly contact lens with low water content. Instead, Bi-weekly contact lenses or Monthly contact lenses may not feel comfortable early in use. If you are uncomfortable, use Daily contact lenses with high water content and reduce usage time.
8. Meet your ophthalmologist and test your eyes to see if your contact lenses are right for you.
As I said earlier, our eyes blink and cycle through tears. When you blink, water, oil, and other substances, such as proteins, come out of the tear glands and form a protective layer on the skin of your eyes. The barrier prevents dry eyes and keeps them moist. But there are people who don’t have this capability. When you use contact lenses, people who lack these features easily feel uncomfortable when they are full of eyes or when they use contact lenses. Therefore, you should meet your eye doctor or optician to test your contact lenses to see if they are suitable for you and to get a prescription for your contact lenses.
9. Blink your eyes.
We sometimes forget to blink when we see digital devices or focus on one place. However, this habit makes the eyes drier. It is necessary to blink your eyes on purpose once every three seconds to keep them dry. This stimulates the tear glands, applying tears evenly to the eyes, allowing them to retain longer protective barriers that prevent dryness.
10. If you have a lot of eye fatigue, reduce contact lens use time and use your eye glasses in parallel.
Excessive use of contact lenses for long periods of time can cause eye problems. As a typical example, corneitis, conjunctivitis, etc. can cause problems. To reduce these side effects, contact lenses should be reduced and glasses should be used in parallel. Use glasses whenever possible when you get home after outdoor activities. Occasionally, you should wear contact lenses when sleeping and remove contact lenses when sleeping. Oxygen transmission in the eyes may decrease, causing side effects of corneal edema. For the sake of the health of your eyes, we recommend that you use it in parallel with your glasses.
This is 10 Things you need to know about using contact lenses. You should be as careful as you can because once your eyes are damaged, it is very difficult to recover. I hope you will be familiar with safe use and keep your eyes healthy.
