For most people, getting the first set or pair of contact lenses feels like an upgrade, especially if you were used to eyeglasses. According to St. Louis Eye Doctors- Crown Vision, perhaps that’s because most people believe dealing with contact lenses is much easier than having to wear eyeglasses. All you have to do is pop them in and are good to go! They are designed to fit rather easily onto the surface of the eye so that you can perform a wide range of tasks without having to deal with the discomfort or inconvenience that can be caused by glasses. You can travel and exercise without having to worry about your glasses falling off or being broken. However, contact lenses may not be the perfect solution because they can also cause problems if not worn correctly. Below are some of the common side effects associated with wearing contact lenses.
Many people who wear contact lenses experience dry eyes because they lower the amount of tears reaching the cornea, as they absorb a large number of tears to remain soft. The insufficient tears brought about by the lenses may cause dry eye syndrome, which is sometimes characterized by a burning sensation, redness, and itchiness. Too much drying could cause scarring of the cornea, an extremely painful experience. Those experiencing chronic eye dryness are advised to use eye drops for sufficient lubrication of the eyes, which can provide a high degree of relief.
Blockage of Oxygen Supply
The eyes also need some oxygen supply to remain healthy. However, contact lenses rest directly on the surface of the eye, thereby covering the entire cornea and decreasing the quantity of oxygen that reach the wearer’s eye. For healthy eyes, you need a sufficient supply of oxygen. However, you may opt for silicone hydrogel lenses that transmit oxygen better than the conventional ones. Also, they are better in the long run if you are looking for eye contacts that are friendly to the eyes. In general, you should not wear them for long hours without taking them off.
Since they sit directly on the eye, the possibility of eye damage is high. They are likely to scratch the cornea and cause some form of corneal abrasion, especially if not fitted correctly or if the eyes are not adequately lubricated with tears. Going to sleep with the contact lenses on can also increase the risk of corneal abrasion because the lenses trap dirt and sand particles that rub them against the cornea. The abrasions also provide an opening for bacteria and other disease-causing pathogens to seep through, causing a range of eye infections and possible loss of vision.
Irritation when Used with Medication
Certain medications, such as birth control pills, may cause eye irritation and chronic eye dryness when they come into contact with contact lenses. Changes may occur in the tear film, which is affected by imbalance. The imbalance may, in turn, cause burning of the eyes, excessive tearing, and the feeling as if there is a gritty foreign body in the eyes. Therefore, you may want to avoid using contact lenses when taking contraceptive pills.
While most people wear contacts without any issue at all, but knowing the more common problems associated with contact lens wearing can help you decide if they are right for you.
