[Clinical Edge] Can Using Artificial Tears Too Often Make Your Eyes Stop Producing Tears?

 A common concern among people with dry eyes is whether frequent use of artificial tears can make the eyes "dependent" on them or cause the tear glands to stop producing natural tears.

The good news is that current evidence does not support this concern. In general, using artificial tears—even frequently—does not make your tear glands become "lazy."

Do Artificial Tears Reduce Natural Tear Production?

Artificial tears are designed to supplement your natural tear film and keep the surface of the eye comfortable and well-lubricated.

Unlike medications that suppress gland function, artificial tears do not switch off or weaken your tear glands. Their purpose is simply to replace or stabilize the tear film when your eyes are unable to do so adequately.

For most people with dry eye disease, using artificial tears as needed is both safe and appropriate.

Is It Safe to Use Artificial Tears Frequently?

Yes, especially if you are using preservative-free artificial tears.

Many people with moderate to severe dry eye use preservative-free lubricating drops multiple times a day under the guidance of their eye care professional.

However, if you need eye drops very frequently every day, it may indicate that your dry eye requires additional treatment rather than simply more lubrication.

What If Your Eyes Become Dry Again Soon After Using Eye Drops?

If your symptoms return quickly after each application, the problem may involve more than a lack of tears.

Other common causes include:

  • Meibomian gland dysfunction (MGD)
  • Blepharitis (eyelid inflammation)
  • Poor tear quality
  • Ocular surface inflammation
  • Increased tear evaporation

In these situations, treating the underlying cause is often more effective than increasing the number of artificial tear applications.

When Should You Be More Careful?

One important consideration is whether your eye drops contain preservatives.

Artificial tears with preservatives may irritate the ocular surface if used very frequently throughout the day. If you require frequent lubrication, preservative-free formulations are generally preferred.

You should also see an eye care professional if you experience:

  • Persistent or worsening dry eye symptoms
  • Eye pain
  • Significant redness
  • Blurred vision that does not improve
  • Increasing sensitivity to light

These symptoms may indicate a condition that requires evaluation beyond routine dry eye treatment.

Bottom Line

Using artificial tears frequently does not make your tear glands stop working or become dependent on eye drops.

However, if you find yourself needing artificial tears constantly with only short-lasting relief, it's worth discussing your symptoms with an eye care professional. Modern dry eye treatment often involves addressing the underlying cause—not just replacing tears.

Note for international readers: Artificial tears are available worldwide under many different brand names. While formulations vary by country, the general principles discussed here apply to most over-the-counter lubricating eye drops. Preservative-free products are generally preferred for people who need frequent daily use.

The short answer is: In many cases, the market may have already priced it in. Why Does the Market Move Before the News? Stock prices often appear to move because of news.

[Clinical Edge] My New Glasses Make Me Dizzy — Should I Keep Wearing Them?

 Feeling dizzy, uncomfortable, or slightly nauseated after getting new glasses is not unusual. Especially when your prescription changes significantly or your astigmatism correction is different, your eyes and brain may need time to adjust to the new visual information. However, not every uncomfortable feeling is simply an adjustment period. How long does it take to adjust to new glasses? For many people, adaptation takes: A few days Up to 1–2 weeks During this period, it may help to wear your new glasses consistently rather than switching back and forth between old and new glasses. If the prescription change is large, you may start by wearing them for shorter periods and gradually increase the wearing time. When should you have your glasses checked again? You should consider returning to your optician or eye doctor if: Dizziness continues for more than 2 weeks Straight lines or objects look tilted One eye feels significantly different from the other You develop headaches or severe...

[Clinical Edge] Should You Wear Your Glasses During an Amsler Grid Test?

  Yes—if you normally wear reading glasses or near-vision glasses, you should wear them during an Amsler grid test. The goal of the Amsler grid is to detect changes in your central vision , not blurry vision caused by an uncorrected prescription. Performing the test under your usual reading conditions helps you obtain the most reliable results. Why Should You Wear Your Reading Glasses? An Amsler grid is a simple tool used to monitor the health of the macula, the central part of the retina responsible for sharp vision. It helps detect changes such as: Wavy or distorted lines (metamorphopsia) Missing or blurred areas in central vision New blind spots If your near vision is naturally blurry because you are not wearing the glasses you normally use for reading, it can become difficult to tell whether you're seeing a true retinal change or simply an out-of-focus image. For the most accurate results, perform the test the same way you normally read a book or use your smartphone. What If Y...
