RX insert Guidance

Welcome to our RX insert FAQ guide. Our aim is to provide you with comprehensive information about the RX prescription options to help you make an informed decision about its suitability for your needs. Whether you’re considering the RX insert for shooting glasses or other activities, we’ve compiled this guide to address common questions.

RX Insert: Fit, Material, and Sizes

An RX insert is a specialised component designed to accommodate prescription lenses within shooting glasses or other eyewear. It works by providing a separate space or compartment where the prescription lenses can be inserted.

“RX” stands for “prescription.” It is commonly used as an abbreviation for a medical prescription. Therefore, an RX insert is an insert that is customised with prescription lenses to provide vision correction for individuals with specific eyesight needs.Β 

Our RX inserts are crafted using TR90, a high-quality plastic renowned for its remarkable characteristics. This material strikes the perfect balance by offering exceptional durability, featherlight construction, and impressive flexibility.

The utilisation of TR90 in our RX inserts ensures an ideal solution for accommodating prescription lenses. You can enjoy the benefits of robustness and a lightweight design, without compromising on the flexibility required to seamlessly fit your prescription lenses.

Suitability for your sport

For prescription glasses specifically designed for shooting sports, individual needs and factors vary. Factors like eye position during aim or gun mount are crucial in shooting sports like clay shooting and archery.

To ensure optimal visibility through the RX insert, it’s important to consider and test the position of coming into anchor or mounting the gun. Our RX inserts are designed to be as large as possible, but it’s possible to have some peripheral vision of the frame, similar to regular prescription glasses.

We suggest trying the frame before filling the prescription to ensure comfort and suitability for shooting.

Considerations & optical power Limits

Staying within the recommended prescription range specified for the RX inserts is advisable to ensure optimal vision and minimise potential distortion. If your prescription falls outside this range, alternative options or specialised solutions may be necessary. We recommended to consult with an eye care professional for guidance.

Model – 2RX

The recommended prescription strength range for the 2RX insert is between -2.50 and +2.50. This means that if your prescription falls within this range, the RX insert should be able to accommodate your prescription lenses effectively.

Prescriptions strengths outside of this range are considered unsuitable for the RX insert. If the prescription is too strong (beyond -2.50 or +2.50), the resulting lenses may become too thick. Thick lenses can potentially cause distortion in the visual field, affecting the clarity and quality of your vision through the shooting glasses.

Model – Fulcrum

The recommended prescription strength range for the 2RX insert is between -3.00 and +3.00.

The curved design of the RX inserts complements the wrap-around style of shooting glasses, requiring a prescription lens that matches its curvature. Unlike regular flat-frame glasses, the lenses for the insert are typically flat when tested for your prescription. This means that the lens prescription does not take into account the angled positioning of the lenses in a wrap-around style.

Curved prescription lenses have certain limitations in terms of power range. Flat lenses, on the other hand, can accommodate higher levels of correction. The reason for this lies in the thickness of the lens as prescription power increases. Thicker areas can be found at the edges or centre of the lens, depending on your specific correction needs.

Exceeding the limits of prescription strength can result in various issues:

  1. Improper Fit: The lens may not fit properly in the insert due to excessive thickness at the edges.
  2. Lens Interference: Contact between the insert and the front lens can lead to damage and potential fogging.
  3. Discomfort: Thickening in the center of the lens may cause contact with your eyelashes, leading to discomfort.
  4. Visual Aberrations: Going beyond the recommended limits can cause visual aberrations or defects in the visual image.

It’s crucial to understand that the RX insert is suitable for customers with weak to medium prescriptions. For those with stronger prescriptions or concerns, it may not be feasible to manufacture a curved lens for the insert without adverse side effects. It is advisable to consult your optician for further guidance and advice based on your specific prescription and concerns.

In cases where your prescription strength slightly exceeds the limits of the RX insert, options may still be available to make it suitable for your needs. Alternative lens options, including thinner and lighter materials, can help accommodate stronger prescriptions.

We highly recommend consulting with your optician to fully explore these possibilities and gain a comprehensive understanding of the available options.

Astigmatism is a widespread vision condition characterised by an irregular curvature of the cornea or lens, leading to blurred or distorted vision. This irregularity affects how light is processed by your eyes, necessitating specific corrections for clear vision.

Identifying Astigmatism in Your Prescription
If your prescription includes corrections for astigmatism, you will notice CYL (cylinder) and AXIS values for one or both eyes, indicated by either a minus (-) or plus (+) sign in the CYL section. These values are crucial for crafting lenses that accurately correct your vision.

Tailoring Lens Options for Astigmatism
The extent to which astigmatism can be accommodated varies by individual conditions and the specific model of glasses:

Model – 2RX: Suitable for an astigmatic correction up to -1.25 diopters.
Model – Fulcrum: Can accommodate an astigmatic correction up to -1.50 diopters.

Understanding the Axis
The AXIS value on your prescription represents the orientation of astigmatism. It is measured in degrees, with 90 indicating a vertical orientation and 0 indicating a horizontal one. For effective correction, the astigmatism axis should align closely with either the vertical or horizontal axis. This alignment ensures that prescription lenses can adequately correct vision, minimising blur and enhancing stability.

However, if the astigmatism lies on an oblique axis (e.g., 60 degrees), it might introduce some visual instability or “wobble.”

It’s important to consult with your eye care professional, who can evaluate your specific needs and recommend the most suitable lens options. They can provide guidance on how best to address your astigmatism within the context of our RX insert models, ensuring you achieve the best possible visual clarity.

  • O.D. (Right Eye) and O.S. (Left Eye): These abbreviations specify the eye to which the prescription applies.
  • Sphere (SPH): The sphere indicates the lens power required to achieve clear vision. A minus (-) symbol signifies nearsightedness, while a plus (+) symbol indicates farsightedness.
  • Cylinder (CYL): If you have astigmatism, the cylinder number denotes the lens power needed to correct it. If this field is left blank, you do not have astigmatism.
  • Axis: When astigmatism is present, the axis number specifies the lens angle that does not contain cylinder power and corrects the astigmatism.
  • ADD: The “add” column represents the additional prescription power required for multifocal lenses such as bifocals.
  • PD (pupillary distance): This is the measurement between the centres of your pupils, ensuring proper alignment of prescription lenses for optimal vision correction.
Pupillary Distance (PD) is the distance measured in millimeters between the centers of your pupils. This measurement is vital for ensuring the optical centers of the lenses precisely align with your eyes, which is crucial for clear, accurate vision. RX inserts are generally engineered to cater to a wide spectrum of standard PD measurements. Our inserts are suitable for individuals with a PD up to 66mm. It’s important to be aware that if your PD is wider than average, choosing an RX insert might not be the best option for you. A PD wider than the recommended range could result in you noticing the edges of the frame within your field of vision and experiencing optical aberrations.

While it is generally recommended to have your pupillary distance (PD) measured by a professional during an eye examination, it is possible to measure your PD at home using a simple method. Stand 8 inches away from a mirror with a ruler. Close your right eye and align the ruler’s 0 mm with the centre of your left pupil. Without moving the ruler, close your left eye and open your right eye. The millimeter reading aligned with the center of your right pupil is your PD. For accuracy, repeat the process a few times and calculate the average.

Varifocals and bifocals are not ideal for shooting glasses as they are designed with various focal points in the middle of the lens. In shooting sports, where the gaze may not always be centred, such as during archery anchor or gun mount for clay shooting, using varifocal or bifocal lenses can result in unexpected distortions.

Varifocal and bifocal lenses are better suited for traditional flat-lens glasses rather than curved RX inserts. For curved inserts, it is recommended to use single-vision lenses to minimise distortions. However, it’s important to note that individual preferences and experiences may vary. If you are considering using varifocal or bifocal lenses in an RX insert, we recommend consulting with a specialist to assess your specific needs and provide personalised advice.

Filling your prescription

At present, we do not offer a prescription filling service. We provide the RX insert frame only. However, we recommend consulting a competent optician, such as your local independent optician specialising in optometry. They can provide expert guidance on the suitability of the RX insert for your prescription and assist in filling the frame with your desired prescription.

We advise against seeking prescription services from large chain opticians or supermarket-based optical centers. Based on feedback from our clients, it appears that some of these establishments may sometimes decline to fill prescriptions for inserts, often due to the perception of insufficient financial incentive rather than an actual inability to provide the service. Consequently, we strongly recommend consulting with smaller, independent opticians who are typically more willing to offer personalised services and accommodate unique requirements like our RX inserts.

If you are involved in shooting sports and would like a more specialised optician familiar with shooting-specific requirements, we suggest searching for a shooting-specific optician. They will have experience in catering to the unique needs of shooters and can provide tailored solutions for your prescription shooting glasses.

The cost of putting prescription lenses in the inserts can vary depending on several factors, including the type of lenses, the lens material, the thicnkess and any additional coatings or treatments. Generally, the cost of prescription lenses can range from Β£50 to Β£250. It is best to consult with your local optician or optical retailer to get an accurate cost estimate based on your specific prescription and lens preferences. They can provide you with a detailed breakdown of the pricing and available options.

We recommend opting for high-quality optical lenses with anti-reflective (AR) coating for our RX inserts. These lenses provide superior vision clarity, reduce glare, and minimise distractions. It is important to prioritise quality over cost when choosing lenses to ensure optimal visual performance and satisfaction. Going for cheaper alternatives may compromise the overall visual experience and durability of the lenses. Invest in lenses that are specifically designed to meet your vision needs and enhance your shooting sports activities.
