Long-term contact lens use is generally safe, when used properly, but it does carry significant **risks and potential complications**, especially with poor hygiene or overuse.

Eye Infections: 

- **Most serious risk**—can lead to **corneal ulcers** and even **vision loss**
- Caused by bacteria, fungi, or amoebas (e.g., *Acanthamoeba keratitis*)
- Risk increases with **overnight wear**, **poor cleaning habits**, or **extended wear lenses**

Reduce oxygen supply: 

- Contacts reduce the amount of oxygen reaching the cornea
- Over time, this can lead to **corneal swelling**, **blood vessel growth into the cornea**, or **corneal thinning**

Dry Eye Syndrome 

- Contacts can disrupt the tear film, causing chronic dryness, irritation, and blurry vision
- Long-term wearers often experience worsening symptoms over time

Corneal Abrasion: 

- Contacts can scratch the surface of the eye if inserted incorrectly or if debris gets under the lens
- Even minor abrasions can increase the risk of infection

Contact Lens Intolerance 

- Some users develop intolerance over time—eyes become red, irritated, or unable to wear lenses for more than short periods
- This can result from long-term inflammation or immune response

Other Risks: 

- **Giant Papillary Conjunctivitis (GPC)**: an allergic reaction on the inner eyelids from lens wear
- **Poor night vision or halos** if lenses don’t sit properly
- **Lens overwear**: wearing lenses longer than recommended shortens their lifespan and increases risk
