Contact lenses are a convenient and effective way to correct vision, offering freedom from glasses and a clear, natural field of view. However, when contacts aren’t worn or cared 
for properly, they can lead to irritation, infection, and even long-term eye damage. At Valley Eyecare Center, we regularly see preventable eye issues caused by simple contact lens mistakes. Knowing what to avoid can help keep your eyes healthy and comfortable.
Sleeping in Contact Lenses
One of the most common—and most harmful—mistakes is sleeping in contact lenses that are not approved for overnight wear. When your eyes are closed, oxygen levels drop. Contacts further limit oxygen reaching the cornea, increasing the risk of infections, inflammation, and corneal ulcers.
Even lenses labeled for extended wear can raise your risk of complications if worn overnight too frequently. If you wake up with red, painful, or blurry eyes after sleeping in contacts, remove them immediately and contact your eye doctor.
Wearing Contacts Longer Than Recommended
Many people stretch their contact lens wear time to save money or out of convenience. Daily lenses are reused, two-week lenses are worn for a month, and monthly lenses go even longer. Over time, lenses accumulate protein deposits, bacteria, and debris that can irritate your eyes and reduce oxygen flow.
Wearing lenses past their recommended schedule increases your risk of dry eye symptoms, allergic reactions, and infections. Following the replacement schedule prescribed by your optometrist is essential for protecting your eye health.
Poor Cleaning and Storage Habits
Improper lens cleaning is another major cause of eye problems. Common mistakes include:
-
Topping off old solution instead of replacing it
-
Rinsing lenses or cases with tap water
-
Failing to clean the lens case regularly
Tap water can contain microorganisms that are dangerous to the eyes, and reused solution loses its disinfecting power. Always clean lenses with fresh, doctor-recommended solution and replace your contact lens case every few months.
Ignoring Eye Discomfort or Redness
Many contact lens wearers push through discomfort, assuming redness, dryness, or irritation is normal. It’s not. These symptoms can be early warning signs of infection, inflammation, or dry eye disease.
If your lenses feel uncomfortable, your vision becomes blurry, or your eyes feel gritty or sensitive to light, remove your contacts and schedule an eye exam. Early treatment can prevent more serious complications and help preserve your vision.
Wearing Contacts When Your Eyes Are Dry
Dry eye disease is common, especially in Phoenix’s dry climate. Contact lenses can worsen dryness by disrupting the tear film, particularly if Meibomian gland dysfunction or eyelid inflammation is present. Wearing contacts when your eyes are already dry can lead to burning, redness, and blurred vision.
At Valley Eyecare Center, we evaluate tear quality, eyelid health, and gland function to determine whether contacts are right for you—or if specialized lenses or dry eye treatments are needed.
Skipping Regular Eye Exams
Even if your vision seems fine, skipping annual eye exams can allow problems to go unnoticed. Contact lens prescriptions are medical prescriptions, and your eyes can change over time. Exams help ensure your lenses still fit properly, provide adequate oxygen, and aren’t causing hidden damage to the cornea.
Regular exams also allow your optometrist to detect early signs of infection, dryness, or contact lens intolerance before symptoms become severe.
