Summary: Contact lenses can come with a series of issues that must be addressed as soon as they are noticed by the wearer.
Wearing contact lenses for an extended period of time can cause changes in the cornea in terms of tear production, oxygen levels, and structure. These changes may lead to irritation, or in severe cases, infection. The good news, however, is that they are not without their respective solutions.
Irritation and Itchy Eyes
Contact lenses have a tendency to trap irritants, such as pollen, smoke, dust, and makeup. Their buildup can lead to itchiness and irritation – and possibly conjunctivitis if it becomes infected. This is why you need to prioritize taking care of your contact lenses. After use, be sure to take them out and clean them according to the manufacturer’s instruction to prevent infections.
Sensitive to Light
Wearing contacts for a prolonged period of time can lead to abrasions and corneal ulcers that make the eye extremely sensitive to light. Although this can occur over time, it’s still noticeable to the point where you should consult with your eye doctor. Other possible causes of abrasions can include dirt, sand, and certain medications.
This can occur when you wear expired or dirty contact lenses. In severe cases, this can be the result of diseases such as macular degeneration, cataracts, or glaucoma. If you fear that the underlying cause of your blurred vision is one of the aforementioned diseases above, it would be wise to speak with a professional immediately to avoid further changes in your vision. The best way to reduce the chances of an infection is to take care of your contact lenses and only use them as directed by your eye doctor.
