Segment Height is the vertical measurement from the bottom of your lens to the top of the segment line in multifocal or progressive lenses. It ensures the transition between lens zones (distance, intermediate, and near) aligns with your natural line of sight.
How to Measure Segment Height:
- Wear your chosen frames:
- Ensure they sit comfortably in your natural position.
- Stand in front of a mirror or have someone assist:
- Measure from the bottom edge of the lens to the center of your pupil.
- Get a professional fitting:
- An optician typically measures segment height during an in-store fitting for the most accurate results.

Anti-reflective (AR) coatings are highly effective in specific environments and for particular activities. Their best use cases include:
- Indoor Environments: Excellent for reducing glare from artificial lighting, including fluorescent lights and screens.
- Computer Use: Perfect for minimizing eye strain and enhancing clarity during prolonged screen time.
- Night Driving: Reduces glare from headlights and streetlights, making driving safer and more comfortable in low-light conditions.
- Photography and Presentations: Eliminates reflections on lenses, ensuring your eyes remain visible in photos, videos, and during public speaking.
For outdoor activities or environments with high exposure to dust, dirt, or UV rays, consider:
- Polarized Lenses: Ideal for reducing glare from reflective surfaces like water, snow, or car hoods, especially in bright sunlight.
- UV-Blocking Lenses: Protects your eyes from harmful UV rays while maintaining lens durability.
- Scratch-Resistant Coatings: Adds an extra layer of durability to lenses for rugged outdoor use.

Prescription and Lens Customization
Your eyeglass prescription includes specific terms and numbers that indicate the corrections needed for your vision:
- OD, OS, and OU
- OD (Oculus Dexter): Information for your right eye.
- OS (Oculus Sinister): Information for your left eye.
- OU (Oculus Uterque): Refers to both eyes.
- SPH (Sphere)Indicates the lens power required to correct your vision:
- Nearsighted (Myopia): Marked with a minus (-) sign. Difficulty focusing on distant objects.
- Farsighted (Hyperopia): Marked with a plus (+) sign. Difficulty focusing on close objects.
- CYL (Cylinder)Specifies the lens power needed to correct astigmatism (difficulty focusing due to irregular cornea shape):
- Nearsighted Astigmatism: Marked with a minus (-) sign.
- Farsighted Astigmatism: Marked with a plus (+) sign.
Note: If your prescription has a CYL, it will always include an AXIS value.
- AXISDefines the orientation of astigmatism correction:
- Measured in degrees, ranging from 0 to 180.
- This specifies the exact position of the astigmatism on your eye.
- ADD (Addition)
- Indicates additional lens power for reading or bifocal/varifocal glasses:
- Shows how much magnification is needed for close-up tasks or intermediate distances.
- PRISMUsed to correct conditions like a lazy eye or squint:
- This adjustment shifts the focus of the lens to align the image properly on the retina.
- Included in prescriptions for special vision needs.
If you have questions, consult our Prescription Guide.
Pupil Distance (PD) is the distance, measured in millimeters, between the centers of your pupils. It ensures that the lenses in your glasses are correctly aligned with your eyes, providing clear and comfortable vision.
How to Measure PD:
- Measure Your Own PD: Stand 8 inches from a mirror, close one eye, and use a ruler to measure from the center of one pupil to the other.
- With a Friend’s Help: Ask a friend to measure your PD while you keep your eyes still, looking at a distant object.
Refer to the image below for step-by-step instructions:

Remember to measure your PD 3–4 times for accuracy. The average adult PD range is 54–74mm, and for children, it’s 43–58mm.
Glasses Information
At RX-Safety, we provide simple ways to ensure your frames fit comfortably:
- Try Before Adding Prescription Lenses:
All RX-Safety frames can be purchased as non-prescription glasses. This allows you to try them on and ensure the fit and style are right before customizing with prescription lenses. - Check Frame Markings:
Look inside your current frames for size markings, which typically include measurements for:- Lens Width: The horizontal width of the lenses.
- Bridge Width: The distance between the two lenses.
- Temple Length: The length of the arms that rest on your ears.
These measurements are key to finding a similar fit.
- Use Our Frame Sizing Guide:

Finding a frame that works with your prescription is essential for comfort and visual clarity. Here are some tips:
- Flat Frames for Higher Prescriptions:
If you have a higher prescription, choose frames with flatter lenses and minimal curvature. This helps reduce lens thickness and ensures better clarity. - Consider Frame Height for Multifocal Lenses:
For progressive or bifocal prescriptions, select frames with sufficient height to accommodate all viewing zones (distance, intermediate, and near). - Durable Materials for Strong Prescriptions:
Higher prescriptions may require stronger frame materials to support thicker lenses without warping or stress.
If you’re unsure, our customer service team is ready to assist:
- Live Chat: Use the chat feature on our website for real-time help.
- Call Us: Speak directly with a team member at
888-245-6638.

Yes, all safety glasses on our RX-Safety website meet stringent safety standards:
- Frames: All safety frames come with the ANSI Z87 marking, ensuring they meet impact resistance and durability requirements.
- Prescription Lenses: Prescription lenses are stamped with our proprietary “PS” maker’s mark, certifying them as safety-approved and compliant with ANSI Z87 standards.
These markings confirm that your safety glasses are suitable for industrial, construction, and other high-impact environments where ANSI-certified eyewear is required.
Single Vision Lenses: Traditional lenses designed to correct a single field of vision, such as distance, intermediate, or near. These lenses are cost-effective and widely used.
Digital Single Vision Lenses: Manufactured using advanced digital technology to provide:
- Sharper optics with reduced peripheral distortion.
- Wider fields of view, especially beneficial for higher prescriptions.
- Enhanced clarity for a more comfortable viewing experience.
Digital lenses are ideal for anyone seeking the next level of optical precision.

Yes, we offer both:
- Lined Trifocals: These lenses have three distinct viewing zones: distance, intermediate, and near.
- No-Line Progressive Bifocals: Also known as progressive lenses, these provide a seamless transition between distance and near vision without visible lines.
For more details, visit our Lined Trifocal Lenses page.
Both materials are lightweight and impact-resistant, but they have unique advantages:
- Polycarbonate:
- Cost-effective and durable.
- Slightly lower optical clarity than Trivex.
- Trivex:
- Superior clarity and lighter than Polycarbonate.
- Better for higher prescriptions and extended wear.
Blue blocker lenses filter out blue light from screens and devices, reducing eye strain and improving sleep.
- Most blue blocker coatings are nearly invisible but may reflect a subtle blue or yellow tint in certain lighting conditions.
- This does not affect lens clarity or vision.
Mirror coatings and transition lenses are incompatible due to the conflicting technologies:
- Mirror Coating: Reflects light and maintains a static finish.
- Transition Lenses: Adapt dynamically to UV light, changing their tint.
Combining the two would compromise the functionality of both.
