Contact lenses are loved and used by many people. It is a convenient and effective way to correct vision, but there are potential long-term consequences and risks associated with their use.

Dry Eyes

Chronic contact lens wear can reduce the production of tears and lead to dry eye symptoms.

Corneal Health Issues

There have been many advancements to improve the way contact lenses provide oxygen, but misuse and overwear can lead to a lack of oxygen and unwanted blood vessels forming on the cornea. The longer you wear contact lenses, the more noncompliant you become with hygiene and lens care, increasing the risk for corneal abrasions and ulcers.

Lens Related Complications

Long-term lens wear can sometimes alter the shape of the cornea, potentially affecting vision stability or requiring adjustments to your prescription. This happens due to a lack of oxygen to the cornea combined with uneven pressure from lenses, such as the use of weighted astigmatism-correcting lenses.

Preventative Measures and Management

  • Regular eye tests: To manage eye health and ensure proper fit and vision for your contact lenses.
  • Proper hygiene and handling of lenses.
  • Avoid overwearing: Don’t wear lenses longer than 12 hours a day and replace your lenses as they are scheduled to. Giving your eyes regular breaks from wear, especially when you notice discomfort, allows for the cornea to heal and restore itself.

By being vigilant about these aspects and maintaining regular consultations with your eye care professional, you can help mitigate the long-term risks associated with contact lenses and maintain healthy vision.
