Contact lenses are a safe method of ensuring you improve your vision. However, their safety depends on a variety of factors, which this article will discuss.
Your eyes need to breathe, and this translates to ensuring they get enough oxygen. Contact lenses can reduce the oxygen flow to the front of your eyes. The longer you put on your contact lenses, the lower the oxygen that gets to the eyes. Such a limit leads to red veins appearing, warping of the cornea and ultimately, impaired vision. You can ensure you do not suffer from these by wearing your contact lenses for a limited period, usually 10 hours at most. You may also consider silicone hydrogel contact lenses which permit an oxygen flow of up to 5 times more than regular contacts.
Further, cleanliness plays a vital role in the safety of your lenses. Dirty contacts lead to infections since they encourage the growth of bacteria on the outer and inner surfaces of the lenses. Such diseases, one of which is conjunctivitis, lead to discomfort, but if it prevails, it can cause blindness. The best way to ensure your contact lenses are clean is by disinfecting them with contact lens solutions. Your optician can recommend the ideal solution for your lenses. Besides cleaning, poor storage can lead to an accumulation of dirt on the lenses. You should, therefore, disinfect the case of your lenses often and after about three months, consider replacing it. Still, you might be tempted to dilute the cleaning solution, which can reduce its effectiveness and expose you to the risk of infections.
As with any medication where your doctor prescribes a dosage for you to follow, contact lenses also require a specific routine. The optician will advise you on the best methods of storing the contact lenses so that they can remain in top shape for a long while. For instance, you get to know how long to wear the contact lenses, after how long you should replace them, how often to clean the contacts and help you know which products you should use. The more time passes before you replace your contacts, the higher the chances of exposure to infections as the grime prevents oxygen from circulating in your eyes, causing irreparable damage sometimes. Moreover, your optician will recommend the frequency of a contact lens eye exam. Such periodic tests help to keep your eyes safe by detecting any problems that may have arisen in the course of using contact lenses.
