Hydrogen Peroxide and Contact Lens
On hydrogen peroxide and contact lenses
In recent times, the use of contact lenses has become more and more widespread. However, the way of cleaning and maintenance is related to the health of the eyes and cannot be ignored. Among them, the role of hydrogen peroxide in contact lenses is particularly critical.
Hydrogen peroxide, the chemical name hydrogen peroxide, has strong oxidizing properties. It is used for contact lens care and can effectively kill many germs. Because of its oxidative properties, it can destroy the structure and function of microorganisms, achieving the effect of disinfection and sterilization. However, its strong oxidation also affects the material of contact lenses.
Contact lenses are made of various materials, including hydrophilic hydrogels and breathable silicone hydrogels. Contact with hydrogen peroxide may cause the material to age and become brittle. Soaking contact lenses with hydrogen peroxide for a long time may reduce their oxygen permeability, which affects the comfort of wearing and eye health. For example, some hydrogel contact lenses, after long-term action of hydrogen peroxide, may have subtle cracks on the surface, causing the lens to be easily damaged, and may affect the transmission of nutrients in tears, hindering corneal support.
If you want to use hydrogen peroxide to care for contact lenses, you must follow the specifications. Common care solutions contain special formulas that can neutralize the strong oxidation of hydrogen peroxide. When using, contact lenses should be soaked in a care solution containing hydrogen peroxide for a specific period of time to fully disinfect them. After neutralization, the residual hydrogen peroxide can be removed before wearing. If not completely neutralized, residual hydrogen peroxide into the eyes can cause eye tingling, redness and swelling, or even damage to the corneal epithelium.
In short, hydrogen peroxide in contact lens care has the advantages of disinfection and sterilization, but also has the disadvantages of affecting the material. Users should be reasonable and operate according to the correct method to ensure the service life of contact lenses and eye health.
