Common causes of contact lens discomfort

There are a number of reasons your contact lenses could feel uncomfortable, and in some cases, there may be more than one cause. So, if you’re wondering why your contacts feel weird, here’s a list of some issues your eye doctor may identify.

Incorrect prescription

Sometimes, contact lens discomfort can happen if your prescription isn’t correcting your vision well enough. This may be caused by an inaccurate fit or vision changes, which can happen subtly or slowly over time. This is why if it’s been more than a year since you last renewed your prescription, it could be time to see your eye doctor to make sure it's up to date. 

How to read contact lens prescriptions

Lens fit

While from a distance eyes generally look the same, up close, each eye has a unique curve and shape. When your contact lens doesn’t fit the unique shape of your eye correctly, it may cause discomfort.

Risks of poorly fitting lenses:

  • Air or debris underneath the lens, potentially causing discomfort
  • Improper tear exchange, which could harm the health of your cornea
  • Excessive lens movement that feels uncomfortable or blurs your vision
  • Damage to the surface of your eye

Understanding contact lens fitting

Issue with your lens

While it's not common, lenses can get chipped, cracked, or torn. If a contact lens feels uncomfortable, check it to see if the discomfort could be caused by any of these issues, and if so, replace the lens. Your contact lens may also be inside-out. Remember, before you put on each contact lens, check it to make sure it looks like a bowl with straight edges. If it looks like a saucer with flared edges, it's inside out.  

Dry eye

Your tears serve multiple purposes. They help protect your eyes from microorganisms and debris, lubricate the surface of your eye, help provide clear vision, and nourish the surrounding tissues. Dry eye occurs when the tear film (made up of oil, water, and mucus) either isn’t sufficient, or evaporates too quickly. It may make your eyes feel gritty, irritated, inflamed, watery or cause blurry vision. If you wear contact lenses and experience dryness symptoms, it may exacerbate the discomfort or cause the lenses to feel like they’re sticking to your eyes more.

What may cause it:

  • Environmental factors like low humidity
  • Excessive screen time leading to reduced blinking
  • Aging—tear production may decrease with age
  • Certain medications or diseases
  • Contact lens wear

If you’re experiencing dryness symptoms frequently when you wear contact lenses, let your eye doctor know. They may perform dry eye assessments, recommend a different type of contact lens, and/or recommend another vision correction type altogether.  

Allergies

Allergens like dust, pollen, mold and pet dander can trigger an immune response in your eyes leading to itching, redness, and discomfort. To make matters worse, allergens can stick to contact lenses, causing your eyes to be in constant contact with the irritant. If you struggle with allergies while wearing contact lenses, talk to your eye doctor. They may recommend daily disposables to ensure you start each day with a fresh pair, or if your allergies are severe enough, they may recommend taking a break from contacts during peak allergy seasons.

Hygiene routine issues

Anything that’s not supposed to be on or under your contact lens (really, anything other than contact lens rewetting solution, eye drops approved for use with contact lenses, or multipurpose contact lens solution) can cause irritation, discomfort, and even vision-threatening problems such as infection. That includes:

  • Deposit buildup from failure to follow prescribed cleaning and care routines
  • Makeup accidently smeared on or under your contact lenses
  • Dust, dirt, or debris
  • Eyelashes

Always remember to wash your hands with mild soap and dry them thoroughly with a link-free towel before handling your contacts.

FAQs

Frequently asked questions

Why does my contact lens feel uncomfortable in just one eye?

Only your eye doctor can determine why your contact lens might be uncomfortable in just one eye. They may identify a poor fit, debris trapped underneath, or an underlying condition like dry eye or an issue with your cornea.

Why does my eye hurt when I put on contacts?

Putting on contact lenses should not be painful. Pain when putting contacts on could be caused by damaged lenses, inverted lenses, dry eye, a poor fit, a scratched cornea or something else. If you experience pain when putting in your contacts, take them out and see if they’re inside out or damaged. If damaged, replace them. If they’re inside out, flip them over and try again. If the pain doesn’t go away, reach out to your eye doctor. 

Why does my eye hurt after removing my contacts?

If your eye hurts after removing your contacts, it may be a scratch, irritation, or infection. If you’re experiencing eye pain after removing your contact lenses, contact your eye doctor.

Why do my eyes feel weird after taking contacts off?

Weird can mean many things, so the best person to talk to about this would be your eye doctor. You can try to describe how your eye feels weird and then they can help determine why you feel that way.

Why do my eyes hurt when I wear contact lenses all day?

If your eyes hurt when you wear your lenses for long hours, it’s important to talk to your eye doctor as soon as you can. Contact lenses are meant to be comfortable for all-day use. Potential causes your eye doctor may identify include dryness, deposits, or poor fit.
