Distance PD is used for viewing objects at a distance (Single Vision Distance Lens), while Near PD is used for viewing objects up-close (Single Vision Near Lens. These measurements are used when producing your lenses to ensure optimal visual acuity.

OD: Oculus Decter - This is latin for Right Eye.

OS: Oculus Sinister - This is latin for Left Eye.

Prism is a measurement used to improve binocular vision comfort. A Prism measurement is prescribed by your optometrist if needed.

Prism is included in a prescription to help the eyes comfortably co-ordinate the image binocularly. Base Up or Down refers to vertical alignment correction, while Base In or Out refers to horizontal alignment correction.

Add is used for reading additions. This is extra power used to correct presbyopia. It is common for prescriptions to include reading addition values as it is primarily used in progressive lens applications or Single Vision reading.

The Cylinder (CYL) refers to the amount of lens power which is needed to correct an astigmatism. This helps correct blurred or distorted vision as a result of irregular shaped ocular structures like the cornea or lens. This is a very common condition.

PD refers to your Pupillary Distance. This is the measured distance between the pupil centre of your right and left eye. This measurement is used to position the optical lens centre of your glasses directly in front of your pupil centre for optimal visual acuity and comfort. You may have two values for your PD, one for near applications and one for distance applications.

The Sphere (SPH) refers to the amount of lens power which is needed to correct your far-sightedness or near-sightedness. A SPH measurement is used to apply a optical power across the entire lens.

The Axis refers to the direction of your astigmatism. This is measured in degrees and is used by our lab to apply the correct astigmatic power to your lenses for optimal visual acuity.

Single vision distance lenses are prescription glasses designed to correct vision at one specific range - typically for seeing distant objects clearly.

They are ideal for people with refractive errors such as myopia (nearsightedness) and are commonly worn for driving, watching TV, or seeing clearly when you're outdoors. These lenses feature one, uniform prescription across the entire lens, providing consistent clarity for distance vision.

Single Vision Near lenses are used to correct your near vision to see things up-close like reading. They're for people who suffer from hyperopia (farsightedness).

In most cases, a prescription can be used for both long and short vision correction and prescription safety glasses can be used for all your optical needs. If you are unsure, seek advice from your optometrist.

No, If your prescription has expired, please see your optometrist for an updated script. Using expired scripts can cause inferior visual acuity and visual discomfort. It is suggested that you use an updated prescription for any purchase for the best visual experience and longevity.

For our SafeStyle®️ prescription safety glasses range, yes - you must have a optical prescription. You may be contacted upon ordering if the script is unusable or requires attention. Otherwise, contact your optometrist for advice.

No, contact lens prescriptions are measured differently to prescription glasses. Please ensure you have a script for glasses - this will ensure visual acuity.

Your Prescription Safety Glasses should be replaced every 24 months, which is valid age of your Prescription. Some prescriptions are valid for less than 24 months, depending on your visual condition.

Replace your SafeStyle®️ prescription safety glasses when necessary. This includes:

Your Safety Glasses have been involved with any impact while wearer or not wearing your Safety Glasses, including being dropped on the ground or against hard services.

Any lens surface marks that impair your vision, such as scratches or cracks.

Any lens surface stain that impairs your vision, such as paint or other
liquid or chemicals.

Please note: rules on replacement safety glasses may vary by site. Check with your health and safety representative for more information specific to you.

Generally - If you are unable to interpret your script when ordering - you can upload your prescription file instead to ensure correct production. If you want to understand how the measurements apply to you - it’s always best to speak to your optometrist for personalised advice.

When Ordering - If you are unsure which values should be entered where, you are welcome to contact enquiries@safestyle.com.au and the team will be able to assist.

If your script doesn’t have a PD - you should contact your optometrist. Otherwise, there are online resources where you can measure PD by yourself, at home. "Eye measure" is an app available on the Apple App Store and Google Play store that provides an accurate measurement.

SafeStyle®️ offer multiple lens coatings to choose from: Super Hard Coat (standard on all lenses), VP Multi Coat + Anti Reflective, UV Filter and our Blue Light lens option.

Super Hard Coat (Included as standard): All our lenses feature a durable anti-scratch coating that enhances scratch resistance vs a standard lens for long-lasting protection in both work and leisure environments. Please note that no lens surface or coating is 100% scratch resistant.

VP Multi Coat + Anti Reflective: A durable anti-scratch coating combined with a hydrophobic layer that repels water, oil, and dirt—keeping lenses cleaner and easier to maintain. The anti-reflective treatment also includes a back-surface coating that absorbs light reflected off the rear of the lens, such as sunlight entering from the side while driving, for example. This reduces glare and prevents potentially harmful UV light from reflecting into the eye, improving visual comfort and protection

UV Filter: Combines all the properties and benefits of a hard multi coat. Including anti-bacterial protection and additional UV blocker to protect your eyes from the harmful effects of ultraviolet radiation that may reflect back off the surface of the lens

Blue Light: Hard Multi Coated UV lenses, with added UV and blue light filters, provide comfortable vision and reduce eye strain from prolonged blue light exposure. To add blue light lenses - this should be selected in the "choose your lenses" menu rather than the coating menu!

Optical prescriptions are generally usable from 2 years from issue. If you are unsure if your prescription is current, you should contact your optometrist. Using expired scripts can cause inferior visual acuity and visual discomfort.

Generally - the advice from SafeStyle is contact your optometrist to get an updated script.

We offer Single Vision (Distance and Near), Progressive, Occupational and Bifocal lenses. However, our online store can only offer single vision - for other lens options please see a stockist. You can find our prescription stockists here!

Dependant on your script, you can buy SafeStyle prescription safety glasses in clear, tinted, photochromic grey, polarised grey and blue-light blocking.
