Wearing contact lenses can have both positive and negative effects on eye health. While contact lenses can provide a wider field of view, a natural look, and less interference during physical activities, they also require more care and can cause eye infections if not cleaned properly[1][2]. Here are some of the negative effects of wearing contact lenses on eye health over time, based on the search results:
– Oxygen deprivation: Contact lenses cover the cornea of the eye, which can reduce the amount of oxygen that reaches the eyes. Wearing contact lenses for too long can deprive the eyes of oxygen, which can lead to pain, blurred vision, and other problems[2][3][4].
– Dry eyes: Contact lenses can absorb the natural tears in the eyes, leading to dry eyes. This can cause discomfort, itchiness, and redness[2][5][4].
– Eye infections: Wearing contact lenses can increase the risk of eye infections, especially if they are not cleaned properly or washed with unclean hands. Serious eye infections can lead to blindness and affect up to one out of every 500 contact lens users per year[1][6][7].
– Corneal abrasions: Contact lenses can scratch the surface of the cornea, leading to corneal abrasions. This can cause pain, sensitivity to light, and blurred vision[8].
– Changes in corneal thickness and shape: Long-term use of contact lenses can lead to changes in the thickness and shape of the cornea, which can cause vision problems and even vision loss[2][9][10][4].
– Formation of microcysts: Contact lenses can cause the formation of microcysts on the cornea, which can lead to decreased corneal sensitivity and vision problems[2].
– Decreased corneal sensitivity: Contact lenses can decrease the sensitivity of the cornea, which can make it harder to detect eye problems[2].
– Vision loss: Long-term use of contact lenses can lead to vision loss due to corneal damage[2][10][4].
It’s important to note that these negative effects are not guaranteed to occur and can be prevented with proper care and hygiene. Contact lens wearers should follow their eye care provider’s instructions on how to properly wear, clean, and store their lenses to lower their chances of an eye infection[1]. Additionally, it’s important to consult with an eye doctor to determine which option is best for your specific needs.
