How UV Rays Damage Your Eyes

Understanding the danger helps you take it seriously.

What Is UV Radiation?

Ultraviolet light is invisible –

• Higher energy than visible light
• Comes mainly from the sun
• Three types: UVA, UVB, UVC
• Only UVA and UVB reach Earth
• Both damage your eyes

Invisible to you, sunlight still penetrates and affects your eyes.

Short-Term UV Damage

Immediate effects from too much sun –

Photokeratitis (sunburn of the eye) 

• Extremely painful
• Feels like sand in the eyes
• Red, watery eyes
• Blurred vision
• Light sensitivity
• Usually temporary, but very uncomfortable

Happens from

• Bright sun on snow or water
• Welding without protection
• Tanning beds (very dangerous!)
• Extended time in intense sun

Long-Term UV Damage

Cumulative damage over the years causes –

Cataracts

• Clouding of the eye lens
• UV is a major risk factor
• Can develop 10-15 years earlier with UV exposure
• Leading cause of blindness worldwide

Macular degeneration

• Damages the central retina
• UV exposure increases risk
• Can cause permanent vision loss

Pterygium (surfer’s eye)

• Growth on white of the eye
• Caused by UV and wind
• Can grow over the cornea
• May need surgery

Pinguecula

• Yellow bump on eye white
• From UV and irritation
• Usually harmless but unsightly

Skin cancer around the eyes

• Eyelids are very sensitive
• 5-10% skin cancers occur here
• Can be serious

Types of UV Radiation

Know what you’re protecting against.

UVA Rays

Long-wave UV radiation

• Penetrates deep into the eye
• Reaches retina and lens
• Linked to macular degeneration
• Linked to cataracts
• Present all day, year-round

Why it matters – Even on cloudy days!

UVB Rays

Medium-wave UV radiation

• Mostly absorbed by the cornea and lens
• Causes more immediate damage
• The main cause of photokeratitis
• Strongest 10 am-4 pm
• Varies by season

More intense in summer.

UVC Rays

Short-wave UV radiation 

• Completely blocked by the atmosphere
• Not a concern from the sun
• Can come from artificial sources (welding)

Why You Need Protection from Both

Sunglasses block –

• 99-100% of UVA rays
• 99-100% of UVB rays
• Also called “UV 400” protection
• This is essential!

Choosing the Right Sunglasses

Not all sunglasses protect equally!

Essential Features

Look for these on the label

UV 400 protection:

• Blocks 99-100% of UV rays
• This is the most important feature
• Don’t buy sunglasses without this!

Large or wraparound frames

• Block the sun from the sides
• Prevent UV from entering around the lenses
• Better coverage = better protection

Affected-resistant lenses

• Polycarbonate is best
• Protects from injury too
• Especially important for sports and children

Lens Colour and Darkness

Common misconception – Dark lenses don’t equal UV protection!

Truth about lens colour

• UV protection comes from an invisible coating
• Dark lenses without UV coating are dangerous
• They make pupils dilate, letting in more UV

Different colours for different uses

• Gray: True colour perception, bright sun
• Brown/amber: Enhances contrast, good for sports
• Green: Good contrast, comfortable in bright light
• Yellow: Low light, overcast days
• Rose/red: Depth perception, snow sports

Most important – UV protection rating, not colour!

Polarized vs. Non-polarized

Polarized lenses

• Reduce glare from water, snow, and pavement
• Make vision more comfortable
• Successful in driving and water sports
• Don’t provide extra UV protection

Still need UV 400 rating!

Price vs. Protection

Expensive doesn’t always mean better protection

• $10 sunglasses can have UV 400
• $200 sunglasses might not
• Always check the label
• Protection matters more than brand

But quality differences exist

• Better optical clarity
• Scratch resistance
• Durability
• Comfort

When and Where UV Protection Matters Most

Your eyes demand far more sun protection than most people ever realize.

Time of Day

UV rays are strong

• 10 am to 4 pm
• Mid-day sun is the most dangerous
• But UV is present all daylight hours

Protect your eyes even in the morning and evening.

Seasons

Summer has the highest UV

• The sun is most direct
• Longer days
• More outdoor time

But UV is present year-round

• Winter snow reflects 80% of UV
• Spring and fall still have UV
• Never stop protecting!

Weather Conditions

Cloudy days are deceiving

• 80% of UV penetrates clouds
• You can still get UV damage
• Overcast doesn’t mean safe

Wear sunglasses even when cloudy!

High-Risk Locations

More UV exposure at

High altitudes

• UV increases 10-12% per 3,000 feet
• Mountain activities need extra protection

Near water

• Reflects up to 100% of UV
• Doubles your exposure
• Beach, lake, pool all reflect

Near snow and ice

• Reflects up to 80% of UV
• Winter sports need protection
• Skiing and snowboarding are critical

Near sand

• Reflects about 15% of UV
• Beach time needs protection

Open areas

• Less shade means more exposure
• Golf, tennis, hiking
• Outdoor sports

Understanding the UV Index

Know when protection is most critical.

What Is the UV Index?

Daily forecast of UV intensity

• Scale from 0 to 11+
• Predicts risk of sun damage
• Helps you plan protection
• Available in weather forecasts

UV Index Scale

Low (0-2)

• Minimal danger
• Still wear sunglasses for cumulative protection

Moderate (3-5)

• Moderate risk
• Protection is needed during midday

High (6-7)

• High risk of damage
• Protection essential
• Seek shade during midday

Very High (8-10)

• Very high risk
• Extra precautions needed
• Limit outdoor time midday

Extreme (11+)

• Extreme risk
• Take all precautions
• Avoid the sun during peak hours

Check the UV index daily in summer!

UV Index and Your Protection

Adjust protection based on the index

• Higher index = more critical to protect
• Never skip sunglasses when the index is 3+
• Consider additional protection (hat, shade)
• Plan outdoor activities around UV peaks
