How To Neutralize Hydrogen Peroxide Contact Solution
How to neutralize hydrogen peroxide contact lens care solution
Hydrogen peroxide contact lens care solution is widely used because of its strong bactericidal ability, but it must be neutralized before use to avoid harm to the eyes. The following is a detailed introduction to the method of neutralizing hydrogen peroxide contact lens care solution for you:
1. Use a special neutralization device
1. ** Device composition and principle **: A common device specially used to neutralize hydrogen peroxide care solution on the market is usually composed of a specially designed lens case and a built-in neutralization sheet or neutralization column. Take a neutralization column containing platinum catalyst as an example. Its principle is to use platinum as a catalyst to accelerate the reaction of hydrogen peroxide decomposition into water and oxygen. When the treatment solution containing hydrogen peroxide is poured into the mirror case with such a neutralization column, the hydrogen peroxide reacts rapidly under the action of the catalyst: $2H_ {2} O_ {2}\ stackrel {platinum catalyst }{=\!=\!=} 2H_ {2} O + O_ {2}\ uparrow $, thereby achieving neutralization.
2. ** Operation steps **: First, make sure the lens case is clean, and put the contact lenses into the lens card slot of the lens case. Then, pour an appropriate amount of hydrogen peroxide treatment solution into the mirror case and cover the lid. Wait for the specified time, usually 6 to 8 hours, during which the hydrogen peroxide is gradually neutralized under the action of the neutralization device. After the time has arrived, the treatment solution can be safely used for soaking contact lenses.
2. Use a specific neutralizing agent
1. ** Type of neutralizing agent **: Some brands will provide special neutralizing agents. These neutralizing agents are mostly solutions containing specific chemical components, which can neutralize with hydrogen peroxide, so that the treatment solution can achieve a safe pH and chemical properties.
2. ** How to use **: In the container containing the hydrogen peroxide treatment solution and contact lenses, drop an appropriate amount of neutralizing agent according to the instructions in the product manual. After dripping, gently shake the container to fully mix the neutralizing agent with the treatment solution. Let stand for a period of time, usually after a few minutes, to complete the neutralization process. Before use, the pH test strip can be used to check the pH of the treatment solution to ensure that it is within the suitable range for the eyes (usually pH value is between 7.0 - 7.4).
When neutralizing the hydrogen peroxide contact lens treatment solution, be sure to strictly follow the product instructions. If the operation is improper, the incomplete hydrogen peroxide may irritate the eyes, causing eye discomfort, redness and swelling or even damage. Only when the neutralization steps are completed correctly can the treatment solution be used safely to care for contact lenses and protect eye health.
