Treatment ranges from artificial tears to prescription medications
Most people can manage dry eyes with simple lifestyle changes and proper treatment
Overview
Dry eyes, also called dry eye syndrome or keratoconjunctivitis sicca, happens when your eyes don't make enough tears or when your tears evaporate too quickly. This common condition affects millions of people worldwide and can make daily activities uncomfortable. About one in every five adults deals with dry eyes at some point in their lives.
Your tears are more complex than they seem. They have three layers: oil, water, and mucus. Each layer protects and nourishes your eye's surface. When any layer is missing or not working properly, you develop dry eyes. The condition becomes more common as you age, especially after 50. Your tears also fight infections and keep your eyes clear, so having healthy tears is really important.
Women experience dry eyes more often than men, particularly after menopause. While dry eyes rarely cause serious vision problems, they can significantly impact your quality of life and make simple tasks like reading or using a computer challenging. The good news is that understanding dry eyes helps you find the right treatment for your situation.
Symptoms & Signs
Dry eye symptoms can vary from person to person and may come and go throughout the day. Many people notice their symptoms are worse in certain environments or during specific activities. Symptoms can be mild or severe, and they may affect one eye or both eyes.
Primary Symptoms
Burning or stinging sensation - Your eyes may feel like they're on fire, especially in dry or windy conditions
Scratchy or gritty feeling - It feels like sand or small particles are stuck in your eyes
Excessive tearing - Your eyes may water more as they try to compensate for dryness
Blurred vision - Your vision may become unclear, especially when reading or using screens
When to Seek Care
Contact your healthcare provider if you experience persistent eye pain, sudden vision changes, or discharge from your eyes. These symptoms might indicate a more serious condition that needs immediate attention. You should also seek care if over-the-counter treatments don't help after several weeks. If your eyes feel red and irritated all the time, even with treatment, tell your doctor right away.
When to Seek Immediate Care
Get emergency medical help if you have severe eye pain, sudden vision loss, or signs of infection like thick discharge or fever.
Causes & Risk Factors
Understanding what causes dry eyes can help you prevent and manage the condition. Many factors can disrupt your tear production or cause tears to evaporate too quickly. Dry eyes happen when something stops your eyes from making enough tears or keeping tears on the surface.
Medications are a common cause of dry eyes. Antihistamines, decongestants, blood pressure medications, and antidepressants can all reduce tear production. Hormonal changes, especially during menopause, also play a significant role. Environmental factors like wind, smoke, and dry air can make symptoms worse. Indoor heating and air conditioning can also dry out your eyes quickly. Stye vs Pink Eye: What's Causing Eye Irritation? discusses various eye conditions that can cause similar symptoms.
Medical conditions can also contribute to dry eyes. Autoimmune diseases like Sjögren's syndrome, rheumatoid arthritis, and lupus commonly affect tear production. Diabetes, thyroid disorders, and vitamin A deficiency can also lead to dry eyes. Eye surgery, including LASIK, may temporarily or permanently reduce tear production. Some people develop dry eyes after spending many hours looking at computer screens without taking breaks.
Age
Risk increases significantly after age 50, affecting over 30% of older adults

Diagnosis
Getting the right diagnosis is important because many eye conditions can cause similar symptoms. Your doctor will carefully examine your eyes and ask about your symptoms to determine if you have dry eyes. They'll make sure dry eyes are really the problem before starting treatment.
Medical History & Physical Examination
Your doctor will ask about your symptoms, when they occur, and what makes them better or worse. They'll also review your medications and medical history. During the physical exam, they'll look at your eyelids, check how often you blink, and examine the surface of your eyes under magnification. Understanding Styes: Causes, Symptoms, and Treatment Options explains how doctors examine eye conditions. Your doctor might ask how much time you spend on screens and about your work environment.
Diagnostic Testing
Schirmer test - Measures tear production by placing paper strips under your lower eyelids
Tear breakup time test - Checks how quickly tears evaporate from your eye surface
Fluorescein staining - Uses special dye to highlight damaged areas on your cornea
Treatment Options
The goal of dry eye treatment is to restore normal tear function and reduce symptoms. Most people find relief with a combination of treatments tailored to their specific needs. Treatment works best when you start early and stick with it consistently.
Conservative Treatments
Artificial tears - Over-the-counter eye drops that replace missing moisture and can be used as often as needed
Warm compresses - Apply for 10-15 minutes daily to help oil glands in your eyelids work better
Eyelid hygiene - Gentle cleaning of your eyelid margins removes debris and improves gland function
Environmental modifications - Use a humidifier, avoid direct air flow, and take breaks from screens
Many people start with these simple treatments and see good results. Using artificial tears before your symptoms get bad is more helpful than waiting until your eyes hurt. Warm compresses are especially useful because they help unclog the tiny oil glands in your eyelids that make tears better.
Advanced Treatments
Prescription eye drops - Cyclosporine (Restasis) or lifitegrast (Xiidra) reduce inflammation and increase tear production
Punctal plugs - Tiny devices inserted into tear ducts to prevent tears from draining away too quickly
Intense pulsed light therapy - Uses light pulses to improve oil gland function in your eyelids
Advanced treatments work when basic treatments aren't enough. Your doctor will decide which treatment is right for you based on how bad your dry eyes are. These treatments often take a few weeks to start helping you feel better.
Living with the Condition
Managing dry eyes is an ongoing process that requires attention to your daily habits and environment. With the right approach, most people can significantly reduce their symptoms and maintain comfortable vision. Living well with dry eyes means making small changes that add up to big improvements.
Daily Management Strategies
Take regular breaks from screens using the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds. This helps you blink more completely and gives your eyes a rest. Stay hydrated by drinking plenty of water throughout the day. Can Telehealth Help With Pink Eye? discusses how technology can help manage eye conditions while being mindful of screen time. You should also blink slowly and completely throughout the day, as many people don't blink enough when looking at screens.
Keep artificial tears with you and use them before your eyes feel dry. This prevents symptoms rather than just treating them. Protect your eyes from wind and sun with wraparound sunglasses when outdoors. Remove contact lenses if your eyes feel too dry, and talk to your doctor about switching to different lenses or glasses.
Exercise & Movement
Regular exercise improves blood circulation, which can benefit your tear glands. However, protect your eyes during outdoor activities, especially in windy or dusty conditions. Swimming in chlorinated pools may worsen dry eye symptoms, so consider wearing swim goggles. Yoga and stretching exercises can also help relax your face and eyes.
Prevention
Preventing dry eyes starts with understanding what makes them worse for you. Everyone's triggers are different, so pay attention to when your symptoms appear. Making small changes now can prevent dry eyes from becoming a bigger problem later.
Manage your environment - Use a humidifier in dry indoor spaces and position yourself away from direct air currents from fans or air conditioning
Practice good screen habits - Take frequent breaks from computers and phones, and make sure your screen is slightly below eye level
Stay hydrated - Drink plenty of water and limit caffeine and alcohol, which can contribute to dehydration
Protect your eyes - Wear sunglasses outdoors and avoid rubbing your eyes, which can worsen irritation
Preventing dry eyes also means being careful with your eyes in winter when indoor heating dries out the air. Use a humidifier to add moisture to your home, and keep your face away from heating vents. If you work in an office, ask if you can move your desk away from air conditioning units.
Frequently Asked Questions
