Lens Care&Info
Geo Circle Lens Authentication
All the lenses that we sell are authentic and straight from the Korea manufacturer. GEO Medical launched their Anti-Fake System to prevent people from buying fake lenses made from China. Once you receive your lenses, locate the sticker and scratch it to see the 20 digit code. Put your 20 digit code here: http://www.fw1860.com/en/ to verify that the lenses you receive from us are in fact 100% genuine and safe to wear! How to Take care of Your Contact Lenses Contact lenses should be cleansed, rinsed and disinfected every day and none of the three steps can be missed. 1. | Cleaning: Different cleansers should be used for different types of lenses. For soft contact lenses, put the lens in your palm, shake the cleanser and add one or two drops onto the lens. Rub it gently with your middle finger to remove the dirt. After cleaning one side of the lens, turn it over and clean the other side. It takes 1-2 minutes to clean one lens. For hard contact lenses, apply the cleanser, hold the lens and rub it with your index finger and thumb so that both sides of the lens can be cleansed simultaneously. | 2. | Rinsing: The purpose of rinsing lenses is to thoroughly wash away the cleanser, which is detrimental to the eye. You can use tap water to rinse hard contact lenses or rigid gas permeable lenses. Soft contact lenses must be rinsed with bottled sterile saline, not home-made saline or tap water. For rinsing, put the cleansed lens on your palm, add some tap water or sterile saline onto the lens and rub it with your middle finger to wash away the cleanser. | 3. | Disinfecting: After cleaning, the lenses should be put in a storage solution for disinfection. It is relatively simple to disinfect hard contact lenses or rigid gas permeable lenses as you only need to place them in the storage solution. However, disinfecting soft contact lenses is more complex and below are three methods: - Heat disinfection: Put the cleansed and rinsed lenses into the lens case, add some sterile saline into the case before heating it to 80 degrees Celsius for 15 minutes. The disinfection procedure is then complete. The lenses can be used after cooling down. The advantages of this method are that it is effective and no eye allergy or discomfort will be caused as only sterile saline is used in the process. The disadvantage is that the heat may cause damage to the lenses and shorten their life span. Usually, the lenses have to be replaced within a year.
- Hydrogen peroxide disinfection: Put the cleansed and rinsed lenses into hydrogen peroxide solution for disinfection. As hydrogen peroxide is detrimental to the eye, the lenses disinfected by hydrogen peroxide solution have to go through a neutralization process before wearing. There are many ways for neutralization, such as to take the lenses out of the hydrogen peroxide solution and put them into a neutralizing solution. Or you can put a neutralizing pill or a neutralizing metal ring into the hydrogen peroxide solution with the lenses. The whole disinfection and neutralization process can last from tens of minutes to several hours. The advantage is that eye allergy can be avoided if the hydrogen peroxide is completely neutralized. The disadvantage lies in the complexity of the process, which includes disinfection and neutralization, and neither of them can be omitted. What’s more, the lenses must never be used before the neutralization process is completed.
- Chemical disinfection: Put the cleansed and rinsed lenses into a disinfection solution where its chemical components can disinfect the lenses. The process generally takes 4 to 6 hours. The advantages are its simplicity and the fact that the lenses can be worn immediately after being taken out of the solution if necessary. The disadvantage is that the chemical components can diffuse into the lenses. While wearing the lenses, the chemicals may cause discomfort to people who are sensitive to them.

| Removing Protein: Apart from daily cleansing, rinsing and disinfecting, soft contact lenses and rigid gas permeable lenses also require protein removal on a weekly basis. Firstly, dissolve a protein-removing pill in sterile saline before putting the cleansed and rinsed lenses into the protein removing solution for 20 to 40 minutes. The lenses should then be taken out for cleaning and rinsing again before disinfecting. The purpose of using the protein remover is to remove the buildup of protein from tears. This is particularly important for those who have chosen heat disinfection, where the protein removing process must be conducted weekly. The reason is that heat can denature the transparent protein previously deposited on the lenses, forming another kind of opaque protein and resulting in a permanent damage to the lenses. |
