Risks of Wearing Contact Lenses
Contacts lenses are a convenient and popular alternative to eyeglasses for many people. They offer better vision clarity and do not fog up or get in the way during physical activities. However, there are risks associated with wearing contact lenses that should be considered to maintain healthy eyes and prevent complications.
Eye Infections
One of the most significant risks of wearing contact lenses is the chance of developing an eye infection. Improper handling and poor hygiene practices can introduce bacteria or viruses onto the lenses, which can then lead to infections. Infections such as bacterial keratitis can cause the cornea to become inflamed, leading to pain, redness, and even vision loss if left untreated. It is essential to follow hygiene guidelines, such as washing hands before handling lenses and properly cleaning and disinfecting them, to minimize the risk of eye infections.
Corneal Ulcers
Corneal ulcers are open sores on the surface of the cornea, usually caused by infections. While contact lens-related infections can lead to corneal ulcers, they can also arise from other factors, such as extended wear or using lenses past their expiration date. Corneal ulcers can result in symptoms like severe eye redness, pain, sensitivity to light, and blurred vision. Prompt treatment is crucial to prevent complications and potential vision loss.
Allergic Reactions
Some individuals may experience allergic reactions to the materials used in contact lenses or the cleaning solutions. Allergies can lead to symptoms like redness, itching, swelling, and discharge. In severe cases, an allergic reaction can lead to corneal swelling or even a condition known as giant papillary conjunctivitis, which causes irritation and inflammation of the inner lining of the eyelids. If you suspect an allergic reaction, it is best to discontinue use and consult an eye care professional to identify the cause and recommend alternative solutions.
Dry Eyes
Wearing contact lenses can contribute to dry eyes, which is characterized by insufficient lubrication on the surface of the eye. The presence of a lens on the eye can reduce tear evaporation, leading to decreased tear production over time. Dry eyes can cause discomfort, eye redness, blurred vision, and a gritty or burning sensation. It is essential to use lubricating eye drops approved for use with contact lenses and to take regular breaks from wearing them, allowing the eyes to rest and rehydrate.
Corneal Abrasions
A corneal abrasion refers to a scratch or injury on the surface of the cornea. While they can happen for various reasons, wearing contact lenses can increase the risk of corneal abrasions. When a foreign object or dirt gets trapped under a lens, it can cause substantial irritation and potentially scratch the cornea when the lens moves. Corneal abrasions can be painful and may lead to infection if not properly treated. Avoid sleeping in lenses and regularly clean them to reduce the risk of corneal abrasions.
