What Are The Common Causes Of Dry Eyes?

In this article, you will learn about the common causes of dry eyes. Dry eyes can be uncomfortable and irritating, impacting your daily life. By understanding the factors that contribute to dry eyes, you can better manage and prevent this condition. So, let’s dive into the common causes and how you can alleviate dry eye symptoms for better eye health and comfort. What Are The Common Causes Of Dry Eyes?

Have you ever experienced the uncomfortable sensation of dry, gritty eyes? If so, you’re not alone. Dry eyes are a common condition that can affect anyone, regardless of age or gender. But what exactly causes this irritating condition? In this article, we’ll explore the most common causes of dry eyes and provide you with valuable information on how to manage and treat this condition effectively.

Environmental Factors

One of the most common causes of dry eyes is exposure to environmental factors. Things like dry, windy weather, high altitudes, and air conditioning can all contribute to evaporating tears too quickly, leading to dry eyes. If you live in a dry climate or work in an air-conditioned office, you may be more prone to experiencing dry eye symptoms.


  • Use a humidifier in your home or office to add moisture to the air.
  • Wear wrap-around sunglasses to protect your eyes from wind and dust.
  • Take breaks from staring at screens to reduce eye strain.


As we age, our bodies undergo various changes, including changes to our eyes. One common age-related change is a decrease in tear production. This decrease can lead to dry eyes, as our eyes may not have enough tears to stay properly lubricated. If you’re over the age of 50 and experiencing dry eye symptoms, aging may be the cause.


  • Use artificial tear drops to lubricate your eyes throughout the day.
  • Drink plenty of water to stay hydrated, which can help maintain tear production.
  • Consider using a humidifier in your bedroom to prevent dry eyes while sleeping.

Medical Conditions

Certain medical conditions can also contribute to the development of dry eyes. Conditions like Sjogren’s syndrome, rheumatoid arthritis, and diabetes can all affect tear production and quality, leading to dry eye symptoms. If you have a chronic health condition, it’s important to be aware of the potential impact it may have on your eye health.


  • Work closely with your healthcare provider to manage your medical condition effectively.
  • Inform your eye doctor about any underlying health conditions you have.
  • Follow your prescribed treatment plan to prevent complications that could worsen your dry eye symptoms.


Believe it or not, some medications may actually cause or exacerbate dry eye symptoms. Medications like antihistamines, decongestants, and certain antidepressants can all interfere with tear production and quality, leading to dry, irritated eyes. If you’re taking a medication that you suspect may be causing your dry eyes, speak with your healthcare provider about potential alternatives.


  • Ask your healthcare provider if there are alternative medications that may have fewer side effects on your eyes.
  • Consider using lubricating eye drops to alleviate dryness caused by medications.
  • Inform your eye doctor of all the medications you’re taking to determine if they may be contributing to your dry eye symptoms.

Hormonal Changes

Hormonal changes, such as those experienced during pregnancy, menopause, or while taking oral contraceptives, can also impact tear production and quality. These changes can lead to dry eyes as a result of hormonal fluctuations. If you’re experiencing dry eye symptoms during a period of hormonal change, hormones may be the underlying cause.


  • Stay well-hydrated to help compensate for any decrease in tear production.
  • Use artificial tears to alleviate dry eye symptoms.
  • Consider speaking with your healthcare provider about potential hormone therapy options.

Eyelid Problems

Issues with the eyelids, such as eyelid inflammation (blepharitis) or dysfunction of the oil glands in the eyelids (meibomian gland dysfunction), can also contribute to dry eyes. When the eyelids don’t function properly, the tears produced may not spread evenly across the surface of the eye, resulting in dryness and irritation.


  • Practice good eyelid hygiene to prevent or manage blepharitis.
  • Use warm compresses and lid massages to help unclog blocked oil glands.
  • Consider using tear supplements or prescription medications to alleviate dry eye symptoms.

Lifestyle Factors

Your lifestyle habits can also play a role in the development of dry eyes. Factors like smoking, excessive screen time, and poor diet can all impact eye health and contribute to dry eye symptoms. Making positive changes to your lifestyle can help improve your eye health and reduce dry eye symptoms.


  • Quit smoking to protect your eyes from harmful chemicals and pollutants.
  • Follow the 20-20-20 rule: Every 20 minutes, look at something 20 feet away for at least 20 seconds.
  • Eat a balanced diet rich in omega-3 fatty acids and vitamins A, C, and E to support eye health.


If you suffer from allergies, you may be more prone to experiencing dry eyes. Allergens like pollen, dust, and pet dander can trigger irritation and inflammation in the eyes, leading to dryness and discomfort. Managing your allergies effectively can help reduce the frequency and severity of dry eye symptoms.


  • Use allergy medications or eye drops to alleviate allergy symptoms.
  • Keep windows closed during high pollen seasons to prevent allergens from entering your home.
  • Consider using an air purifier to reduce indoor allergens that may trigger dry eyes.

Contact Lens Wear

If you wear contact lenses, you may be at a higher risk of developing dry eyes. Contact lenses can reduce the amount of oxygen that reaches your eyes and interfere with the natural tear film, leading to dryness and discomfort. If you wear contact lenses and experience dry eye symptoms, make sure to take proper care of your lenses and follow your eye doctor’s recommendations.


  • Follow a proper contact lens care routine to minimize the risk of dry eyes.
  • Consider wearing glasses instead of contact lenses on days when your eyes feel particularly dry.
  • Use rewetting drops designed for contact lens wearers to alleviate dryness and discomfort.

Treatment Options

If you’re experiencing dry eye symptoms, it’s essential to seek treatment to alleviate your discomfort and protect your eye health. There are various treatment options available, depending on the underlying cause of your dry eyes. Your eye doctor may recommend one or more of the following treatments:

Artificial Tears

Artificial tears are lubricating eye drops that can help moisten the eyes and alleviate dryness. These drops are available over the counter and come in various formulations to suit different types of dry eye symptoms. You can use artificial tears as needed throughout the day to keep your eyes comfortable and hydrated.

Prescription Eye Drops

In some cases, your eye doctor may prescribe medicated eye drops to help manage inflammation, increase tear production, or improve tear quality. These prescription eye drops are designed to target specific issues that may be contributing to your dry eyes, providing you with more targeted relief than over-the-counter remedies.

Punctal Plugs

Punctal plugs are tiny, biocompatible devices that are inserted into the tear ducts to block drainage and keep the tears on the surface of the eyes longer. By preventing tears from draining too quickly, punctal plugs can help alleviate dry eye symptoms and improve tear retention. Your eye doctor can determine if punctal plugs are the right treatment option for you.

LipiFlow Treatment

LipiFlow is a therapeutic procedure that uses heat and gentle pressure to unclog blocked oil glands in the eyelids. By restoring proper gland function, LipiFlow can help improve the quality of the tears produced and reduce dry eye symptoms. If you have meibomian gland dysfunction, LipiFlow treatment may be an effective option for managing your dry eyes.

Lifestyle Modifications

Making positive changes to your lifestyle can also help improve your dry eye symptoms. By staying hydrated, eating a healthy diet, practicing good eye hygiene, and protecting your eyes from environmental factors, you can support your eye health and reduce discomfort associated with dry eyes. Your eye doctor can provide you with personalized recommendations to help you manage your dry eyes effectively.


In conclusion, dry eyes can be caused by a variety of factors, including environmental conditions, aging, medical conditions, medications, hormonal changes, eyelid problems, lifestyle factors, allergies, and contact lens wear. By identifying the underlying cause of your dry eyes and seeking appropriate treatment, you can alleviate your symptoms and protect your eye health. If you’re experiencing dry eye symptoms, consult with your eye doctor to determine the best course of action for managing your condition. Remember, taking care of your eyes is essential for maintaining your overall quality of life.
