Contact Lens Problems That You Should be Aware Of
Wearing contact lens can certainly help you have a better appearance and correct Myopia (nearsightedness), Hyperopia (farsightedness), Astigmatism (distorted vision) and Presbyopia (need for bifocals), but the contact lens problems must bring you a lot of troubles. Traditional soft or rigid (“hard”) extended-wear contact lenses need to be cleaned on a daily basis by using disinfecting solution and cleaner. And protein should be used weekly to remove the protein deposit formed on the lenses. These lens care procedures cost you a lot of time and money to maintain a pair of extended-wear lenses. In some cases, improper cleaning procedures of contact lenses may cause eyes infection and corneal ulcers; and there are cases that cause blindness.

Potential Problems Of Lens Caring Procedures
Contact lenses risks exist in every user. Although traditional soft or rigid contact lens are far more cheaper than the daily disposable ones, do you want to risk your eyes by saving that little money? Even when you do according to what the optometrist instructs you to do, there is still chance of infection. The daily rubbing and rinsing procedures with your fingers can still leaves traces of dirt and germs on the lenses. If the disinfecting solution fails to function, especially for all-in-one solution, germs, bacteria and debris of dusts will stay in the lenses overnight and get into your eyes the next day. The reason that all-in-one solution fails to disinfect well is that it also functions as a lubricant when wearing contact lens, so the solution cannot contact strong disinfection chemical. When using products convenient like this, you are putting your health at risk. Despite the all-in-one solution, there are cases that the production line of some disinfection solution, such as Renu, got infected and consumers contracted severe cornea infection. Therefore, the chance of infection using extended-wear contact lens is potentially high.
Apart from the daily cleaning routine, the weekly removal of protein never guarantees you to be immune from irritation or infection. When protein deposit is formed when tears lubricate your eyes or when the protein build-up leaves traces in the lenses together with the debris of dusts and dirt, you will feel irritation, discomfort, excessive tears, unusual sensitivity to light and swelling due to the debris deposit formed in the lens. Such discomfort can sometimes be unbearable and intolerance, and even cause allergy and do harms to your cornea and eyes.
Potential Hazards of Extended-wear Contact Lens
What’s more, even the contact lenses are cleaned and rinsed every day and all the proper cleaning procedures are carried out, the constant rubbing on lenses will lead to wear off and scratches or nicks are likely to form in lenses. These scratches will definitely harm and hurt your eyes. Therefore, you must change your contact lens every 9 months to ensure the safety and health of your eyes. In some cases, contact lenses are likely to scratch the cornea when the lenses are worn-out and during improper care of lenses. It is more likely to happen when lenses are worn while sleeping.
To avoid these contact lenses risks, daily disposable contact lens is the best solution. However, if you insist on using extended-wear contact lens, remember to have contact lens eye exam. Your doctor or optometrist will advise you how to carry out proper cleaning procedures.
