Generally, contact lenses are considered safe for eyes when used correctly, with potential risks primarily linked to improper use, such as sleeping in lenses not designed for overnight wear.
Understanding Contact Lenses and Eye Health
Contact lenses are a popular vision correction option worn directly on the eye's surface. Their safety largely depends on proper handling, cleaning, and wear schedule.
The Role of the Cornea
The cornea is a crucial part of your eye. It is the transparent outer layer that acts like a protective shield and helps focus light so you can see clearly. The health of the cornea is vital for good vision.
According to the provided information, contacts rarely harm the cornea. This suggests that, under normal and intended use, contact lenses are not typically detrimental to this essential part of the eye.
Potential Risks Associated with Contact Lens Use
While contacts are generally safe, certain practices can increase the risk of eye problems.
- Sleeping in Contact Lenses: The reference specifically highlights that sleeping in contacts not intended for extended wear can significantly increase the likelihood of:
- A corneal infection
- Even an ulcer on the cornea
This is likely because sleeping with lenses designed for daytime wear reduces oxygen flow to the cornea and can trap bacteria or debris, creating a breeding ground for infection.
How to Minimize Risks
To ensure contact lenses remain good for your eyes, follow best practices:
- Always follow the wear schedule recommended by your eye care professional.
- Never sleep in contact lenses unless they are specifically approved for extended wear and your doctor has advised it.
- Properly clean and store your lenses according to your eye care professional's instructions and the manufacturer's guidelines.
- Replace lenses and storage cases as recommended.
- Wash and dry your hands thoroughly before handling lenses.
- Use only fresh contact lens solution; never reuse old solution or use tap water.
By adhering to proper hygiene and wear guidelines, you can significantly reduce the potential risks associated with contact lens use and help keep your eyes healthy.
