Understanding Z87+ Safety Glasses: Your Ultimate Guide to ANSI Z87.1 Standards


When it comes to protecting your eyes in hazardous environments, not just any eyewear will do. Safety glasses are essential, but knowing which type to choose can be a bit overwhelming. That’s where Z87+ safety glasses come in. They’re not just regular safety glasses; they meet strict standards set by the American National Standards Institute (ANSI) to ensure maximum protection. Let’s dive into what makes Z87 safety glasses a crucial part of your safety gear.

What Are Z87+ Safety Glasses?

Z87+ safety glasses are a specific type of protective eyewear that meets the stringent requirements of the ANSI Z87.1 standard. These glasses are designed to protect your eyes from various hazards like impact, dust, and harmful radiation. The “plus” sign indicates that the glasses offer high-impact resistance, making them suitable for environments where there’s a high risk of flying debris or other dangerous materials.

The ANSI Z87.1 Standard Explained

The ANSI Z87.1 standard has been around for decades, continually evolving to improve safety measures. Initially developed to provide guidelines for protective eyewear, it has become a comprehensive standard that ensures eyewear can withstand impact, optical clarity, and other hazards. The standard covers several aspects, including the marking of lenses and frames, which helps users identify the level of protection their eyewear offers.

Types of Z87.1 Safety Glasses

Impact-Rated Glasses

Impact-rated Z87.1 glasses are designed to withstand high-velocity impacts, making them ideal for jobs involving heavy machinery or tools. These glasses can resist high-speed particles that could otherwise cause serious eye injuries.

Non-Impact-Rated Glasses

While these still offer protection, non-impact-rated glasses are suitable for environments where there is minimal risk of flying debris. They are often used in settings where chemical splashes or dust particles are the primary concern.

Specialty Glasses

These include safety glasses with additional features like tinted lenses for welding, anti-fog coatings for humid environments, and prescription lenses for those who need vision correction.

Material and Design of Z87+ Safety Glasses

Lens Materials

The lenses of Z87+ safety glasses are typically made from polycarbonate or Trivex, both of which are highly impact-resistant and offer excellent optical clarity. These materials also provide UV protection, which is crucial for outdoor work.

Frame Construction

Frames are designed to be durable and comfortable. They are usually made from tough materials like nylon or metal. Some frames feature rubberized components for better grip and comfort during extended wear.

Comfort and Fit Features

Good fit is essential for safety glasses to be effective. Z87+ safety glasses often come with adjustable nose pads and temple arms to ensure a snug fit. This customization helps prevent the glasses from slipping, even during vigorous activity.

Impact Resistance and Durability

The impact resistance of Z87+ protective eyewear is tested rigorously. They must withstand a projectile traveling at a significant speed without cracking or breaking. This testing ensures that in a real-world situation, your eyes are protected from sudden impacts.

UV Protection in Z87+ Safety Glasses

Many people overlook the importance of UV protection in safety glasses. Prolonged exposure to UV rays can cause serious damage to your eyes. Z87+ safety glasses often include UV protection, making them a good choice for both indoor and outdoor work environments.

Anti-Fog and Anti-Scratch Coatings

Benefits of Anti-Fog Coatings

In environments where temperature fluctuations are common, lenses can fog up, reducing visibility and safety. Anti-fog coatings help maintain clear vision in such conditions, ensuring you can see your work clearly at all times.

Advantages of Anti-Scratch Features

Anti-scratch coatings extend the life of your safety glasses by preventing minor abrasions that can cloud your vision. This feature is particularly beneficial in environments with lots of dust or debris.

Prescription vs. Non-Prescription Z87.1 Glasses

If you wear prescription glasses, you don’t have to compromise on safety. Prescription Z87.1 glasses are available and can be customized to your vision needs. Many optical stores and online retailers offer these specialized glasses.

How to Choose the Right Z87+ Safety Glasses

Assessing Your Needs

Consider the specific hazards of your work environment. Are you dealing with high-speed debris, chemical splashes, or UV exposure? Identifying these risks will help you choose the right glasses.

Fit and Comfort Considerations

Ensure the glasses fit well. Look for adjustable features and try them on if possible. A good fit prevents the glasses from slipping and provides better protection.

Style and Functionality

While safety is paramount, style and functionality can’t be ignored. Choose glasses that you feel comfortable wearing for extended periods, and consider additional features like tints or coatings that suit your work environment.

Proper Maintenance and Care

Cleaning Tips

Regularly clean your glasses with a mild soap and water solution. Avoid using abrasive materials that can scratch the lenses. Use a soft microfiber cloth for drying.

Storage Advice

When not in use, store your glasses in a protective case to prevent damage. Keep them away from extreme temperatures and chemicals that could degrade the materials.

Longevity of Safety Glasses

Even the best safety glasses have a lifespan. Regularly inspect your glasses for signs of wear and tear, and replace them if you notice any cracks or significant scratches.

Common Industries and Jobs Requiring Z87.1 Safety Glasses


Construction sites are full of hazards like flying debris and dust. Z87.1 safety glasses are essential for protecting workers’ eyes from these dangers.


In manufacturing, workers deal with machinery and materials that can pose serious eye injury risks. Safety glasses are a crucial part of the personal protective equipment (PPE) in these environments.


Healthcare workers, particularly in labs, are exposed to chemical splashes and biological hazards. Safety glasses help protect against these risks.

Regulatory Compliance and Workplace Safety

OSHA Requirements

The Occupational Safety and Health Administration (OSHA) mandates the use of safety glasses in various industries. Complying with these regulations not only ensures worker safety but also helps avoid hefty fines.

Employer Responsibilities

Employers must provide the necessary protective equipment and ensure that workers are trained on how to use it properly. Regular safety audits can help maintain compliance and safety standards.

Innovations and Trends in Safety Glasses

Technological Advancements

Recent advancements include smart glasses that offer heads-up displays and integrated communication tools, enhancing both safety and productivity.

Future Trends

As technology evolves, we can expect to see even more innovative features in safety glasses, such as better integration with other safety gear and enhanced ergonomic designs.


Choosing the right Z87+ safety glasses is crucial for ensuring eye safety in hazardous environments. By understanding the ANSI Z87.1 standards, the types of glasses available, and how to maintain them, you can protect your vision effectively. Always prioritize safety and compliance in your workplace, and remember that your eyes are invaluable.


What is the difference between Z87 and Z87+ safety glasses?

Z87+ safety glasses offer high-impact resistance, whereas Z87 glasses may only meet basic impact requirements. The “+” indicates they can withstand more rigorous testing.

Can I use Z87.1 safety glasses for sports?

While Z87.1 safety glasses provide excellent protection, they are specifically designed for industrial and workplace hazards. For sports, it’s better to use glasses designed for athletic use.

How often should I replace my Z87+ safety glasses?

You should replace them if they show signs of wear and tear, such as cracks or significant scratches. Regular inspection is key to maintaining safety.

Are all safety glasses ANSI Z87.1 certified?

No, not all safety glasses meet ANSI Z87.1 standards. Always check for the Z87.1 marking to ensure they meet the necessary safety requirements.
