According to Dr. Noah Klein, many patients come to his office complaining of eye redness and eye irritation when wearing their contact lenses. Although they have bought new contact lenses, however the same problem still strike. The problem is with the contact lens solution themselves. Even though there are many high quality lens solution, this won't solve the real problems. Here, everything will be explained.
Acanthamoeba
This type of bacteria is actually a free-living amoeba which will cause permanent blindness of the cornea of the eyes. Most contact lens wearers are at a high risk of being exposed to this bacteria due to insufficient cleaning of their contact lenses. Because of this, Hydrogen Peroxide (H2O2), is mainly and commonly used as a microbial disinfectant as it is the most effective. Most wearers were encouraged and advised to have their solutions hydrogen peroxide based and preservative free saline as well.
Saline
The saline in the solution is designed to clean the lens by removing dirt, external chemicals and residue. Its function is mainly for the storage and cleanliness of the lens before inserting into the eye.
Hydrogen peroxide
Hydrogen peroxide works to remove unwanted buildup of external substances while the contact lens are in storage. It extracts bacteria such as Acanthamoeba and other external elements that are known to cause eye infections like Conjunctivitis.
Chemicals vs. Tear ducts
Our tear ducts naturally produces protein. For contact lens wearer, proteins released by the tear ducts attaches itself to the contact and can cause dryness. In such cases, an enzyme cleaner/ protein remover is used. Hence, eye drop bottles. Other solutions would be temporary or permanently using tear duct plugs. These can prevent the dryness and allowing the eye to retain more moisture. Temporary plugs are made of collagen and permanent, silicone. Both can be removed if necessary.
