Are Contact Lenses Bad For Your Eyes?

Contact Lenses Calgary

When cared for properly, contact lenses are a comfortable and convenient method of vision correction and offer many advantages over traditional eyeglasses.

However, contact lenses are medical devices and failure to wear, clean and store them as directed by your eye doctor can increase your risk of developing certain eye problems such as dry eye and corneal ulcers.

Factors contributing to this include:

  • Poor hygiene
  • Over-extended contact lens wear
  • Environmental factors
  • Reduced tear exchange under the lens

If you wear contact lenses, be sure to book regular eye exams and keep to the contact lens replacement schedule recommended by your eye doctor to ensure long-term corneal health.

Importance of Contact Lens Fittings

Before deciding to wear contact lenses, it’s important to schedule a contact lens fitting with your eye doctor as they will be able to determine which type of lens (including curve, thickness and diameter) best suits your specific vision needs.

Poorly fitted contact lenses can lead to potentially serious ocular problems including:

  • Scratched cornea
  • Dry eyes
  • Sensitivity to light
  • Reduced visual acuity
  • Vision discomfort including itching, redness, stinging and burning

During this eye exam, our Lethbridge eye doctors will take the time to go over proper care instructions including how to clean, handle and store your lenses.


Tips For Proper Contact Lens Care

While contact lenses are usually a safe and effective form of vision correction, they are not entirely risk-free - especially if they are not cared for properly.

No matter what type of lens you opt for, adhering to the recommended care and replacement schedule is essential for long-term eye health.

Tips on How To Protect Your Vision While Wearing Contact Lenses

  1. ALWAYS wash your hands before handling your contact lenses. Use soap and water and dry them with a lint-free towel.
  2. Minimize any exposure to water. Be sure to remove your contact lenses before taking a shower or swimming.
  3. NEVER rinse your contact lenses with water (tap or sterile)
  4. Rinse your contact lens case with solution and NOT with water. Leave it open to dry.
  5. Be sure to follow the specific lens cleaning and storage guidelines as prescribed by your eye doctor.
  6. Replace your contact lens case every 3 months
  7. NEVER use saliva to wet your contact lenses. This is not a sterile solution.

Taking Care Of Your Eyes When Wearing Contact Lenses

Taking good care of your eyes and scheduling regular eye exams is very important when wearing contact lenses. Failure to do so can lead to serious eye health problems such as infections and, in some cases, vision loss.

Tips on Eye Health Care For Contact Lens Wearers

  • If you are experiencing any vision discomfort such as redness, itching, light sensitivity or discharge, remove your contact lenses and contact your eye doctor as soon as possible.
  • Stop smoking. Contact lens wearers who smoke tend to experience more eye health problems than patients who don’t.
  • Schedule regular eye exams. Contact lens wearers should visit their eye doctor at least once a year.
  • These eye exams are also good opportunities for reinforcing proper contact lens care and for ensuring that your prescription is updated.
