National Sunglasses Day is on Sunday, June 27, 2027, and it falls on June 27 every year. It reminds people that sunglasses aren’t just a style choice. They protect your eyes from the sun’s ultraviolet (UV) rays.
When Is National Sunglasses Day?
It’s always June 27. It’s an awareness day, not a federal holiday. It lands near the start of summer, when people spend more time outside.
Who Started National Sunglasses Day?
The Vision Council, a U.S. trade group for the optical industry, first launched the campaign in 2014, Vision Monday reports. Today it is run by The Vision Council Foundation.
The campaign asks people to post photos in their favorite shades with #NationalSunglassesDay. In 2026, the United Opticians Association joined as a partner.
The group’s research points to a real gap. More than 37% of U.S. adults go without proper UV eye protection, The Vision Council Foundation says. Its 2025 figures, reported by Vision Monday, put the share who don’t wear sunglasses regularly at nearly 40%.
Sunglasses are big business too. About 30 million pairs of non-prescription sunglasses sell through optical stores each year, the foundation says. That’s roughly 10% of the market.
Why UV Protection Matters
UV damage to the eyes builds up over time and can’t be undone, Vision Monday notes. That’s why daily protection matters, not just at the beach.
The American Academy of Ophthalmology (AAO) links UV exposure to several eye problems:
- Cataracts: clouding of the eye’s lens, which blurs vision.
- Pterygium: a growth on the white of the eye.
- Eye cancers: including cancers of the eye and eyelid.
- Photokeratitis: a painful, temporary sunburn of the eye from intense UV.
Children and people with light-colored eyes may face higher risk, the AAO says. That makes sunglasses a smart habit to start young.
How to Choose Sunglasses That Protect
The AAO says the most important feature is a label showing the lenses block 100% of UV rays. In its 2014 survey, fewer than half of buyers checked for it. Other tips:
- Dark doesn’t mean safe: lens darkness and UV protection are separate.
- Bigger is better: oversized or wraparound frames block more light from the sides.
- Polarized helps with glare: it cuts reflection from water and roads but doesn’t add UV protection.
- Price isn’t protection: low-cost pairs labeled 100% UV-blocking can work as well as pricey ones.
How to Celebrate National Sunglasses Day
- Check your labels: make sure every pair you own blocks 100% of UV rays.
- Share a selfie: post a photo in your shades with #NationalSunglassesDay.
- Protect the kids: get children a well-fitting pair with full UV protection.
- Keep a spare: stash an extra pair in your car or bag.
- Book an eye exam: ask your eye doctor about prescription sunglasses if you need them.
- Add a hat: a wide-brimmed hat adds more shade for your eyes and face.
Frequently Asked Questions
Do I need sunglasses on cloudy days?
UV rays can pass through clouds, so wearing sunglasses outdoors on overcast days is still a good habit.
Are polarized sunglasses better for your eyes?
Polarized lenses reduce glare, which helps when driving or near water. They don’t add UV protection, so still check for a 100% UV label.
Do kids need sunglasses?
Yes. The AAO says children may be more vulnerable to sun damage. Choose a well-fitting pair labeled 100% UV protection, and add a brimmed hat.
Do expensive sunglasses protect better?
Not necessarily. The AAO says inexpensive sunglasses labeled 100% UV-blocking can protect just as well as costly ones.
