A pair of eyes given by the GOD almighty is the most precious thing of a human being. It becomes our responsibility to take care of it and do not let any thing harm it in any case. The increasing trend of wearing contact lenses has given rise to many companies that manufacture contact lenses and contact lens solutions. If you are lucky and fortunate enough, you can afford to have the expensive lenses and solutions from medical stores. Whereas the people who cannot afford too much, get trapped into the scams of companies that make low quality contact lens solutions and make people fool. This results in severe eye infections and allergies which are quite expensive to cure.
Usually the toxicity of a contact lens solution determines the nature of the solution. It might be the active ingredient of it or the catalyst that speeds up the reaction between the enzymes in your eyes and the solution itself. There are many types of contact lens solutions that can be considered as crucial if not bought from a genuine dealer. They include cleaning, rinsing, disinfecting, multipurpose, rewetting and artificial tear products solutions. The contact lens solution toxicity is related to corneal inflammation. When you wear soft contact lenses in daily wear, you tend to get used to of the lenses and feel as if they are naturally there. If your lenses are not properly washed by a proper contact lens solution then those pretty green eye contacts or the Korean big eye contacts can become a nightmare for you.
The question that many people ask to themselves is, Can I be allergic to my contact lens solution? The answer is positive. If you possess any of the symptoms of eye infection or contact lens’s discomfort then you should immediately withdraw the use of that product and buy something else that is more appropriate and reputed in the market. If you see any of the symptoms in your eyes like red eyes, itching in the eyes, pain, unusual and irregular tearing, decreased vision, discharge like pus from the eyes and most importantly the inability or discomfort that comes in between wearing the contact lenses, you should get a medical advice from a certified ophthalmologist and get yourself examined.
Corneal infiltrative events (CIEs) in soft contact lens daily wear were checked with respect to contact lens solution’s toxicity via various diseases. The conclusion came out to be that the eyes that are suffering from the ill effects of contact lens solution toxicity are often prone to develop corneal infections. Since cornea is a very sensitive part of the eye after conjunctiva, therefore contact lens solutions should be chosen very carefully and intelligently. To prevent yourself from falling into the prey of contact lens solution toxicity, you should take care of your lenses in every manner. Keep them washed and soaked all the time. Let the nozzle of the solution’s bottle not get contaminated. Keep your eyes covered while going in an industrial or slum area. Last but not the least, do not wear such contacts that are harsh on your eyes and irritate you all the time.
Toxicity in Consumer Products
As an assignment for my Sustainable Marketing class, we were asked to choose one of our frequently used personal care products and check the toxicity levels of its ingredients. The product I chose was my soft contact lens solution.
The Effect of Nonpreserved Care Solutions
It has long been established that chemically preserved contact lens solutions have adverse effects on the corneal epithelium,30 31 with a significant correlation between preservative-induced epithelial toxicity and lactate dehydrogenase.
Long-term Retinal Toxicity of Intravitreal Commercially
Ten Dutch-belted rabbits were injected with 4 mg/0.1 mL Kenalog in one eye and 0.1 mL physiologic salt solution (PSS) in the fellow eye. Simultaneous bilateral dark-adapted electroretinography was performed 2 weeks and 12 weeks after injection in 10 and 6 rabbits, respectively. …. A small amount of 2.5% methylcellulose gel was applied to the eye, and a contact lens electrode (JET; LKC Technology, Gaithersburg, MD) was placed in contact with the central corneal area.
