Contact Lens Hygiene Mistakes

Millions of people wear contact lenses every day without issue, but even experienced wearers often have habits that put their eyes at unnecessary risk. Many of the most dangerous contact lens mistakes feel harmless in the moment but can lead to painful, sight-threatening infections.

At Upper West Optical, we make contact lens education a core part of every fitting and annual exam, because safe habits are the foundation of comfortable, healthy lens wear for life.

The Most Dangerous Mistakes

💧

Rinsing With Water

Tap water and even distilled water can contain Acanthamoeba, a microscopic organism that causes a devastating corneal infection. Lenses must only ever be rinsed or stored in approved contact lens solution.

😴

Sleeping in Lenses

Unless specifically approved for extended wear, sleeping in contact lenses dramatically increases the risk of corneal infection by depriving the eye of oxygen and allowing bacteria to proliferate overnight.

🏊

Swimming or Showering

Water, whether in pools, hot tubs, lakes, or the shower, should never come into contact with lenses. Waterborne microorganisms can adhere to lens surfaces and cause serious infections.

Common Everyday Mistakes

💊

Topping Off Solution

Adding fresh solution to old solution in the lens case dilutes the disinfecting agents and allows bacteria to survive. Always empty, rinse, and refill with completely fresh solution every day.

🕐

Wearing Beyond Schedule

Stretching daily disposables to two or three days or monthly lenses past their replacement date allows protein and lipid deposits to accumulate, reducing oxygen transmission and increasing infection risk.

🗑

Neglecting the Case

Lens cases are a leading source of microbial contamination. Cases should be rinsed with fresh solution, air-dried face down on a clean tissue, and replaced every one to three months.

      Safe Contact Lens Habits to Follow Every Day
      Wash hands thoroughly with soap and water before handling lenses
Use only fresh multipurpose or hydrogen peroxide solution, never water
Remove lenses before any water exposure including showers and swimming
Never sleep in lenses unless they are specifically approved for overnight wear
Replace lenses on the schedule recommended by your eye doctor
Clean and air-dry your lens case daily and replace it every one to three months
Never share contact lenses with another person under any circumstances
Remove lenses immediately if your eyes become red, painful, or suddenly blurry

    

Signs of a Potential Contact Lens Infection

🔴

Redness and Pain

Sudden redness, pain, or a burning sensation that does not resolve after removing your lenses warrants same-day evaluation, as it may indicate the start of a corneal infection.

👀

Light Sensitivity

New or significantly worsened sensitivity to light while wearing or after removing lenses can be a sign of corneal inflammation or infection that needs prompt professional attention.

🔬

Blurry Vision

Blurring that does not clear with blinking or after lens removal, especially if accompanied by discomfort, should be evaluated urgently rather than attributed to a simple fitting issue.

Annual Exams Are Part of Safe Lens Wear

Contact lens prescriptions expire for good reason. Annual exams allow your eye doctor to assess the health of your corneas, confirm your lenses still fit correctly, and update your prescription if needed. Even if your vision feels unchanged, the health of the eye surface can shift in ways that only a professional examination can detect.

At Upper West Optical, we provide thorough contact lens evaluations and take time to review hygiene and care protocols with every patient, because informed wearers are safe wearers.
