Dry Eye in South Florida, Why Our Climate Makes It Worse

South Florida is humid, so many people are surprised when their eyes feel dry.

• Parents are surprised when children complain of burning, watery, tired, or irritated eyes.
• Adults are surprised when their eyes feel dry in the car, at work, after screens, or after being outside.

But dry eye is not only about living in a dry desert climate.

Dry eye happens when the tear film is not keeping the eye surface comfortable and stable.

That can happen because the eyes do not make enough tears, because the tears evaporate too quickly, or because the quality of the tears is not working well.

In South Florida, dry eye symptoms can be triggered by air conditioning, fans, wind, sun, allergies, screens, contact lenses, pool exposure, sunscreen, outdoor sports, and long school or work days.

So yes, dry eye can happen here.

Even when the weather feels humid.

What Is Dry Eye?

Dry eye happens when the eyes are not properly lubricated.

The tear film is supposed to protect the eye surface, keep vision clear, and make blinking comfortable.

When the tear film is unstable, the eye surface can become irritated.

Dry eye may cause:

• Burning
• Stinging
• Redness
• Watery eyes
• Scratchy feeling
• Gritty feeling
• Blurry vision that comes and goes
• Light sensitivity
• Eye fatigue
• Contact lens discomfort
• Feeling like something is in the eye
• Trouble with screens
• Symptoms worse later in the day

Many people think dry eye means the eyes do not water enough.

But watery eyes can still be dry eye.

Why Watery Eyes Can Be Dry Eye

This confuses many parents and patients.

If the eyes are watery, how can they be dry?

When the eye surface is irritated, the eyes may produce reflex tears.

These tears may spill over or make the eyes watery, but they do not always fix the tear film problem.

• They may not stay on the eye long enough.
• They may not have the right oil layer.
• They may not keep vision stable.

So a child or adult can have watery eyes and still have dry eye or tear film irritation.

Why South Florida Can Trigger Dry Eye

South Florida has humidity, but it also has many dry eye triggers.

Common local triggers include:

• Air conditioning
• Ceiling fans
• Car vents
• Wind
• Bright sun
• Outdoor sports
• Pool chlorine
• Salt water
• Sunscreen
• Allergies
• Mold exposure
• Pollen
• Screens
• Contact lenses
• Long school and work days

Dry eye is often about exposure and tear film stability, not just the humidity number outside.

Air Conditioning Is a Major Trigger

In South Florida, we live in air conditioning.

Homes, cars, classrooms, stores, gyms, and offices are cooled for much of the year.

Air conditioning can dry the eye surface.

Car vents blowing directly toward the face can make symptoms worse.

• Children may complain more in the car, at school, or after sitting near a fan.
• Adults may notice symptoms at work, in exam rooms, in offices, or while driving.

Simple changes can help, such as moving vents away from the face or avoiding direct fan airflow.

Screens Make Dry Eye Worse

Screens are a major dry eye trigger.

When children and adults focus on screens, they blink less often and may not blink completely.

This can make the tear film evaporate faster.

Screen related dry eye may happen with:

• Tablets
• Phones
• Chromebooks
• Laptops
• Gaming systems
• Desktop computers
• Online schoolwork
• Homework
• Work from home
• Long reading on screens

Symptoms may include burning, watering, blinking hard, blurry vision, headaches, and eye fatigue.

If symptoms happen mostly during screens, the answer is not always blue light.

The tear film, prescription, focusing, and screen habits should be checked.

Children Can Have Dry Eye Too

Dry eye is not only an adult problem.

Children may have dry eye symptoms but describe them differently.

A child may say:

• My eyes hurt
• My eyes burn
• My eyes feel tired
• My eyes are watery
• My vision gets blurry
• I need to blink
• The light bothers me
• My eyes feel scratchy
• I do not want to read
• I need a break from screens

Children often rub their eyes when they feel dry or irritated.

That rubbing can make redness and inflammation worse.

Allergies and Dry Eye Often Overlap

South Florida allergies can make dry eye worse.

Allergies can cause itching, redness, watering, swelling, and eye rubbing.

Eye rubbing can irritate the eye surface.

Some allergy medications can also contribute to dryness in some people.

A child or adult can have both allergy and dry eye at the same time.

That means the treatment may need to address both.

• If itching is the main symptom, allergy may be a major piece.
• If burning, watering, screen discomfort, and fluctuating blur are present, dry eye may also be involved.

Contact Lenses Can Make Dry Eye Symptoms Worse

Contact lenses sit on the tear film.

If the tear film is unstable, contacts may feel dry, scratchy, or uncomfortable.

Contact lens dryness may be worse with:

• Long wearing time
• Screens
• Air conditioning
• Allergies
• Outdoor sports
• Wind
• Pool or beach days
• Poor lens fit
• Wrong lens material
• Wearing lenses too long

A child or teen who wears contacts and has red, painful, light sensitive, or blurry eyes should remove the lenses and call the eye doctor.

Do not push through contact lens pain.

Pools and Beach Days Can Irritate the Eyes

South Florida families spend a lot of time near water.

Pool chlorine, salt water, sunscreen, sweat, sand, and wind can all irritate the eyes.

This may create burning, redness, watering, or a gritty feeling.

For contact lens wearers, water exposure is more serious.

Children and adults should not swim, shower, or use hot tubs in contact lenses because water exposure can increase the risk of eye infection.

If vision correction is needed in the water, ask about prescription swim goggles.

Sunscreen Can Trigger Symptoms

Sunscreen is necessary in South Florida, but it can irritate the eyes.

Sunscreen can run into the eyes with sweat or water.

It may cause burning, tearing, redness, and temporary light sensitivity.

This can make dry eye symptoms feel worse.

Helpful habits include:

• Apply sunscreen carefully around the eyes
• Wash hands after applying sunscreen
• Avoid touching contact lenses after sunscreen
• Use hats and sunglasses for added protection
• Remove contacts if sunscreen gets in the eye and causes irritation

If pain, redness, light sensitivity, or blurry vision continues, call the eye doctor.

Wind and Outdoor Sports Can Dry the Eyes

Wind increases tear evaporation.

Outdoor sports, bike rides, beach days, boating, and playground time can all expose the eyes to wind and glare.

• Children may not say their eyes are dry. They may blink, rub, squint, or complain that their eyes hurt.
• Adults may notice symptoms while driving, walking outside, golfing, boating, or watching outdoor sports.

Sunglasses can help protect against wind and glare.

For sports, protective eyewear may also be needed.

Dry Eye Can Make Vision Blurry

Dry eye can cause blurry vision that comes and goes.

This is often because the tear film is unstable.

The tear film is the first surface light passes through when entering the eye.

If the tear film breaks up between blinks, vision can blur.

You may notice:

• Vision clears after blinking
• Vision gets worse during screens
• Vision changes during the day
• Vision is worse in air conditioning
• Contact lenses get blurry
• Reading becomes uncomfortable
• Eyes feel tired but the prescription seems okay

If vision is persistently blurry, schedule an eye exam.

Do not assume it is only dryness.

Dry Eye Can Cause Headaches

Dry eye can contribute to headaches because irritated eyes are working harder to maintain clear, comfortable vision.

This may happen with screens, reading, air conditioning, contact lenses, or long school days.

But headaches can have many causes.

• If headaches are frequent, severe, worsening, associated with vomiting, neurologic symptoms, or waking a child from sleep, call your pediatrician.
• If headaches happen with reading, screens, eye rubbing, blur, light sensitivity, or contact lens discomfort, schedule an eye exam.

Dry Eye Can Look Like Pink Eye

Dry eye can make the eyes red, watery, irritated, and uncomfortable.

That can look like pink eye.

But dry eye is not contagious.

• Pink eye can be viral, bacterial, allergic, or irritant related.
• Dry eye often has symptoms like burning, scratchiness, watering, fluctuating blur, and symptoms worse with screens or air conditioning.

If there is thick yellow or green discharge, significant swelling, pain, light sensitivity, or one eye much worse than the other, schedule an exam.

Dry Eye Can Look Like Allergies

Dry eye and allergies can overlap.

• Allergies usually itch.
• Dry eye usually burns, stings, waters, or feels gritty.

But children may not describe this clearly.

They may just rub their eyes.

If your child is always rubbing, blinking, or watering, the exam can check for both allergy and dry eye signs.

Treating only one piece may not fully help if both are present.

Dry Eye Can Affect Contact Lens Success

A child or teen who wants contacts may struggle if dry eye or allergies are not controlled.

They may complain that contacts hurt, dry out, blur, or feel good at first but bad later.

Options may include:

• Daily disposable contact lenses
• Different lens material
• Shorter wearing time
• Allergy treatment
• Artificial tears approved for contacts
• Better screen habits
• Temporary contact lens break
• Backup glasses

Contact lenses should feel comfortable.

Daily pain is not normal.

Dry Eye and Meibomian Glands

The eyelids contain oil glands called meibomian glands.

These glands make the oil layer of the tear film.

That oil layer helps keep tears from evaporating too quickly.

If the oil glands are not working well, the eyes may feel dry, irritated, watery, or blurry.

This is called evaporative dry eye.

It can happen in adults and children.

Signs may include:

• Burning
• Grittiness
• Watery eyes
• Red eyelid edges
• Styes
• Chalazia
• Crusting
• Symptoms worse with screens
• Symptoms worse in air conditioning
• Contact lens discomfort

The eye doctor can look at the eyelids and tear film to see whether the glands are involved.

Dry Eye and Styes Can Be Connected

Some people with eyelid oil gland problems also get styes or chalazia.

A blocked gland can create an eyelid bump.

If your child keeps getting styes and also has dry, watery, or irritated eyes, the eyelids and tear film should be checked.

The treatment may include warm compresses, eyelid hygiene, allergy management, artificial tears, or other care depending on the exam.

What Parents Can Try at Home

For mild dry eye symptoms without warning signs, you can try:

• Screen breaks

• More complete blinking

• Avoiding direct fans

• Moving air vents away from the face

• Sunglasses outdoors

• Washing face after outdoor play

• Avoiding eye rubbing

• Hydration

• Artificial tears if recommended

• Contact lens breaks if lenses are uncomfortable

• Do not use redness reliever drops regularly.

• Do not use someone else’s prescription drops.

• Do not ignore pain, light sensitivity, or blurry vision.

Screen Habits That Help

For screen related dryness, try:

• Look away from the screen regularly
• Encourage full blinking
• Keep the screen at a comfortable distance
• Increase font size if needed
• Avoid screens too close to the face
• Reduce glare
• Use good room lighting
• Avoid long uninterrupted screen sessions
• Use glasses as prescribed
• Schedule an exam if symptoms continue

The goal is not always to eliminate screens.

The goal is to make visual work more comfortable and healthier.

Contact Lens Habits That Help

For contact lens wearers:

• Do not sleep in contacts unless prescribed for overnight wear
• Do not swim or shower in contacts
• Replace lenses on schedule
• Use the recommended solution
• Do not reuse daily lenses
• Keep backup glasses available
• Remove lenses if the eye is red or painful
• Call with light sensitivity or blurry vision
• Tell the doctor if lenses dry out
• Keep follow up visits

Dryness can often be improved, but contact lens safety rules still matter.

When Should You Call the Eye Doctor?

Call the eye doctor if dry eye symptoms are frequent or if your child has:

• Eye pain
• Light sensitivity
• Blurry vision
• Redness that keeps coming back
• Contact lens discomfort
• Eye rubbing all the time
• Watery eyes that do not improve
• Burning with screens
• Recurrent styes
• Thick discharge
• One eye worse than the other
• Symptoms after injury
• Symptoms after swimming in contacts
• Symptoms after sleeping in contacts

Dry eye is manageable, but the correct diagnosis matters.

What the Eye Doctor May Check

A dry eye evaluation may include:

• Vision
• Glasses prescription
• Tear film stability
• Eyelid health
• Oil gland function
• Allergy signs
• Dry eye signs
• Cornea surface health
• Contact lens fit if relevant
• Screen and work habits
• Medication history
• Environmental triggers

The exam helps determine whether symptoms are from dry eye, allergies, prescription, contact lenses, eyelid inflammation, or another condition.

Dry Eye Treatment Depends on the Cause

Treatment may include:

• Artificial tears
• Allergy treatment
• Eyelid hygiene
• Warm compresses
• Contact lens changes
• Screen habit changes
• Environmental changes
• Prescription eye drops in selected cases
• Treating eyelid inflammation
• Follow up monitoring

Not every dry eye patient needs the same plan.

A child with allergy related rubbing needs a different plan than an adult with screen related dry eye or a teen with contact lens dryness.

Dry Eye Care at Pediatric & Family Vision

At Pediatric & Family Vision, we see children, teens, and adults for dry eye, watery eyes, burning, redness, screen related discomfort, allergies, contact lens dryness, styes, and eyelid irritation.

In South Florida, dry eye often comes from a combination of triggers.

Air conditioning, fans, screens, allergies, contact lenses, pool exposure, wind, sun, and tear film instability can all add up.

We help families understand what is driving the symptoms and create a plan that fits real life.

• Sometimes the answer is simple habit changes and artificial tears.
• Sometimes allergy treatment is needed.
• Sometimes contact lenses need to be changed.
• Sometimes eyelid oil glands need more attention.

If your child or family member has burning, watery, tired, red, scratchy, or blurry eyes, dry eye may be part of the problem.

Humid weather does not rule it out.
