Contact lenses, like everything related to vision, require careful regular care. Without the use of special tools, lenses can become hard, overdried. Their term of use will be significantly reduced, and, in addition, the use of a “dry” lens may cause symptoms of eye irritation.
It is equally important to timely clean lenses, disinfect, remove dusty and protein contaminants. To clean the contact lens safely and gently, use a special peroxide solution.
What is peroxide solution for contact lenses
A cleaning and disinfecting peroxide solution for lenses is a substance that can gently, without mechanical cleaning, remove protein deposits and dirt on eye lenses and almost completely destroy harmful bacteria, viruses, and fungal formations.
To date, all peroxide solutions can be divided into two categories:
- One-stage, allowing to carry out the cleaning procedure in one action, where in order to neutralize hydrogen peroxide, a medical alloy disk containing platinum is used.
- Two-stage, requiring an additional cleaning procedure: first, the lenses are soaked in a disinfectant solution, and after disinfection, they are treated with neutralizing and rinsing solutions.
One of the most popular single-stage systems, One Step Lens Peroxide Solution, is manufactured by Sauflon, the world's leading vision correction company. The peroxide system, whose name literally means "one step", is the result of many years of research in the field of medical optics. Cleaning with this system performs several lens cleaning tasks at the same time: cleaning, moisturizing, lubricating, sterilizing and short-term storage. Due to its ease of use and high antibacterial properties, the One Step peroxide system is in great demand among customers who have already chosen it for the care of eye lenses.
The composition of the solution. What's in the One Step Contact Lens Cleaning Kit
A sterile peroxide solution for lenses always contains an active substance - hydrogen peroxide. It acts as a cleaning and disinfectant. The composition of the One Step system includes: 3% hydrogen peroxide with a buffering agent, poloxamer.
The One Step Peroxide System Kit includes:
- One Step Lens Peroxide Solution - 360 ml or 100 ml.
- Instructions for use of the solution for one-stage cleaning and disinfection of lenses.
- A container in which a platinum-containing metal alloy disk is integrated.
Important! For the cleaning process, you only need to use the catalytic disk container included in the One Step kit. In addition, the container is not recommended to be used after the solution in the bottle is over.
Method of using peroxide solution
One-step step-by-step cleaning of contact lenses with the One Step peroxide system is quite simple:
- Contact lenses are placed in the lens holder of the container.
- A lens peroxide solution is poured into the container to the mark.
- The container is closed by a lid.
- The lenses are left in the container with the solution for a period of six to eight hours until the complete neutralization of hydrogen peroxide.
Important! The main feature of peroxide solutions - the application process should be carried out in strict accordance with the instructions. A non-neutralized solution of hydrogen peroxide can slightly burn the cornea of the eyes and cause discomfort. Therefore, it is so important to keep the lenses in solution for at least six hours. If you do not observe this rule and remove the lenses from the solution ahead of time, the peroxide included in the composition will not be neutralized.
You can not use peroxide solution for lenses with dyes. Processing colored contact lenses with this method can lead to the destruction and leaching of the coloring matter.
Peroxide solution is not intended for long-term storage of lenses. After 24 hours, contact lenses are recommended to be moved to a solution designed specifically for storing lenses. If the lenses have been lying in the peroxide solution for longer - you need to disinfect them again.
Peroxide solution is not intended to moisturize the cornea directly. It is also strictly forbidden to use it as a rinse solution.
