Safety Glasses and Goggles

Safety glasses and goggles look similar from a distance, but they protect against different things. Knowing which to reach for, and keeping them clean and comfortable, is what gets them worn.

What is the difference between glasses and goggles?

Safety glasses are made for general impact protection, such as flying chips and small debris. Good ones have side protection so particles cannot slip in from the edges. They are light, comfortable and work well with hearing protection and caps for much of everyday farm work.

Goggles seal around the eyes. That makes them better for fine dust, heavy splashes and spray, where particles or liquid could come from any direction. They can be warmer and fog more easily, so ventilation and anti-fog options matter.

Neither one replaces the other. The task and the hazard decide which is right, and many jobs call for goggles under a face shield.

• Glasses: impact, light debris, general work
• Goggles: dust, splash, spray
• Face shield on top for heavy tasks

How do I pick the right pair?

Look at the marking on the lens or frame and at the maker's information, which tells you what standard the product meets and what it is meant for. Do not assume that a pair of sunglasses or ordinary glasses is protective. OSHA's eye and face protection pages explain hazards and matching solutions.

Try them on with the gear you will wear at the same time, such as muffs, hard hats and respirators. A pair that slides, pinches or leaves gaps will end up on the dashboard.

If you are buying for a crew, buy a few styles. A pair that suits a wide face may not suit a narrow one, and people wear what feels right on their face.

How should they fit?

A good fit sits close to the face without pressing painfully on the nose or temples. Lenses should cover the eye area well, side shields or goggle seals should touch the face, and nothing should shift when you turn your head or look down.

If you wear prescription glasses, ask about goggles made to fit over them or prescription safety glasses, which are covered in a separate article. Wearing safety glasses over ordinary glasses may or may not fit well, so test the pair first.

• Lenses cover the eye area
• Side shields or seals touch the face
• No slipping when you look down
• Works with muffs and caps

How do I keep them in good shape?

Wash lenses with clean water and a soft cloth made for the purpose, since dry wiping on dusty lenses scratches them. Store them in a case or a clean spot, not loose in a toolbox or on a dashboard in the sun.

Scratched, cracked, pitted or cloudy lenses and bent frames reduce protection and vision. Replace them. Check the strap, the seal and the vents on goggles as well, since worn rubber can let dust in.

Keep a small stock of clean cloths and a lens cleaning station near the shop door. Making cleaning easy makes replacing dirty lenses less of a temptation.

How do I stop fogging and glare?

Fogging is a main reason people take goggles off. Look for ventilated styles and anti-fog coatings, and follow the maker's cleaning instructions so that you do not damage the coating. Take a short break from a task if the lens has fogged heavily rather than working blind.

For bright sun, there are safety glasses with tinted lenses that also meet impact standards. Check the marking, since ordinary sunglasses are not necessarily impact-rated.

Who needs them, and when?

Everyone doing or standing near grinding, cutting, hammering, mowing, trimming, spraying, mixing chemicals, cleaning, and working with grain or feed dust. Family members, kids and visitors who are close enough to be hit should have protection too.

Keep a few clean pairs where the work happens: shop, barn, sprayer shed, grain area and trucks. If the pair is far away, the job will start without it.

• Shop and barn
• Sprayer shed and grain area
• Trucks and tractors

Where can I check standards and advice?

OSHA, NIOSH and university extension programs publish guidance on selecting and using eye protection, and the maker's own instructions give details for each product. Look at what applies to your tasks, since the right type changes with the hazard.

Your eye doctor can also advise, especially if you have vision needs or have had an eye injury before.
