Pick a frame, choose "Add Prescription", select your lens options, and enter or upload your prescription. If you don't have PD (pupillary distance), we'll help you measure it with our online measuring tool.

You'll need a current prescription from your eye doctor (typically valid for 1-2 years), your pupillary distance (PD), and to choose your preferred frame style. If you don't have your PD measurement, we have an online measuring device you can use while placing your order.

The eyeglass prescriptions are typically written in a grid with scientific terms, abbreviations, and numbers. Remember, the further the numbers are from zero, the more correction you need. A+ symbolizes farsightedness and, A- which represents nearsightedness. Other abbreviations are:

• OD – Oculus Dexter, which means right eye.
• OS – Oculus Sinister, which means left eye.
• SPH (Sphere) – Eyeglass prescription power.
• CYL (Cylinder) – Astigmatism is an imperfection in the curvature of the eye.
• AXIS – Degree and direction of your astigmatism need correction.
  (Cylinder and Axis go together as this is the corrections for your astigmatism)
• ADD – Add Power is the magnifying power in the lower part of a multi-focal lens. (ADD power is not needed for single vision distance eyewear.)

PD stands for Pupillary Distance. It is the distance between your pupils which is measured in millimeters. It is needed to input your prescription accurately. This measurement is used to align the optical center of each lens with your pupils to provide the best possible visual clarity. In general, PD measurements fall in the range of 48mm to 73mm. The most common measurements are between 58mm and 68mm. If your PD isn't listed on your prescription, we have a online tool you can use to measure it while checking out.

We offer single-vision, bifocal, and progressive lenses with premium materials like Trivex, polycarbonate, and high-index, plus options for polarized, photochromic, mirrored, and custom tints. We use advanced digital surfacing for ultra-precise optics and can handle a wide range of prescriptions.

Prescription sunglass prices vary depending on frame choice, lens material, coatings, and prescription complexity. Basic prescription lenses start at $50, while premium frames with advanced lens technologies and coatings cost more. Contact us for a personalized quote based on your specific needs.

Think about how and where you’ll be using them—driving, sports, everyday wear, or bright outdoor environments. Consider the level of sun exposure, your need for glare reduction, and whether you’ll be switching between glasses often. Make sure the frame fits comfortably and offers enough lens coverage for sun protection. Choosing the right style depends on both function and lifestyle.

The best frames for your prescription depend on your lens strength and intended use. Higher prescriptions often work better in smaller or rounder frames to reduce lens thickness and distortion. Wraparound styles are great for sports but may have limits for strong prescriptions—Trivex lenses can help in those cases. For progressives, deeper frames offer more room for the full lens design. We can help match your prescription to frames that fit well, look great, and provide optimal vision.

Yes — many sport/wrap styles support prescription lenses. In some cases we'll recommend Trivex or high-index materials, flatter base curves, or an insert to maintain optical performance. We'll advise the best route for your Rx and sport, when you contact our opticians.

We use advanced digital surfacing technology and custom lens calculations to precisely align your prescription’s pupillary distance (PD) and optical center (OC) within high-wrap or curved frames. These adjustments compensate for lens tilt, curvature, and distortion, ensuring clear, comfortable vision.

If your prescription sunglasses don’t fit quite right, most minor adjustments—like tightening temples or improving alignment—can be made at your local optical shop. If the issue is more serious or affects your vision, contact us. We’ll review your order details and, if needed, remake the lenses once under our one-time remake policy to ensure a proper fit and clear vision.

It depends on how you use them. Single-vision is great for distance-only tasks like driving or outdoor sports. Bifocals work well if you need distance and occasional near vision, like reading a map. Progressives are best for all-day wear, offering seamless vision at all distances without visible lines. The right choice comes down to your lifestyle and how you plan to use your sunglasses.

• Polycarbonate: Lightweight, impact-resistant—great for most prescriptions.
• Trivex: Exceptional clarity + impact resistance; excellent for wrap/sport frames.
• High-index: Thinner/lighter for stronger prescriptions available in 1.67 and 1.74 in eyeglasses clear and Transitions GEN S.

Digital prescription lenses use advanced direct digital surfacing to create sharper, more precise optics than traditional methods. By milling the lens from the back, they stay thinner while maintaining accuracy, providing up to a .01 diopter tolerance compared to .12 diopters in standard lenses. This results in clearer vision, wider viewing areas, and less distortion—especially in wraparound or high-curvature frames.

Standard photochromic lenses don’t darken fully in cars because windshields block most UV light. However, Transitions® XTRActive new generation lenses are specially designed to activate behind the windshield, making them the darkest photochromic option for driving. They help protect your eyes from bright sunlight while still offering the convenience of clear indoor vision.

Prescription sunglasses combine vision correction with sun protection. They feature darker tints, UV protection, and often polarization to reduce glare. Unlike clear prescription glasses, they're designed specifically for outdoor use and bright light conditions, providing both visual clarity and eye protection.

UV Radiation can seriously damage your eyes—UVA rays accelerate aging effects, while UVB rays cause burning damage. Dark lenses alone don’t guarantee protection; in fact, they can make your pupils dilate and let in more harmful rays. The safest prescription sunglasses have a UV400 rating, blocking 99–100% of both UVA and UVB. This shields your eyes from long-term harm while keeping vision comfortable outdoors—though you should still never look directly at the sun.

Polarization is optional but strongly recommended for cutting glare from water, snow, and pavement. It's ideal for driving, fishing, and boating. Note: some LCD screens (dash displays) can appear darker with polarized lenses.

• Driving: Neutral gray or brown (polarized) for comfort and true color.
• Fishing/Water: Polarized gray/blue or brown/green to cut surface glare.
• Golf: Brown/amber or rose-copper to enhance contrast on greens.
• Cycling: Brown/rose for variable light, mirror for bright days.
• Shooting: Purpose tints (e.g., orange/copper/rose) tuned to background and light—available in Rx.

Yes. We offer mirrored, flash, and gradient tints on many lens colors and materials. Mirrors reduce surface brightness and add style without changing the underlying tint function.

Yes — premium back-surface AR reduces reflections from behind you (e.g., sunlight entering around the frame) and improves clarity. It also helps keep lenses cleaner. Hydrophobic and oleophobic coatings make cleaning easier and help keep your lenses from scratching.

We offer various tint densities from light (10-20%) to very dark (85-90%) depending on your needs and local regulations. For driving, most locations require at least 25% light transmission. Our opticians can recommend the optimal tint level based on your activities and prescription requirements.

Absolutely! We encourage people to wear prescription sunglasses while driving during the day. If you are driving at night, you should consider a transitions lens that lightens to a clear transparent lens early or late at night. Rx sunglasses will improve your vision, protect you from dangerous UV radiation, and shield you from intense solar reflections.

Prescription sunglasses should not be worn when wearing prescription contact lenses. Prescription contacts already function to improve your vision. As a result, you may get headaches, eye strain, or even vision loss. If you decide to wear contact lenses, we recommend investing in a pair of high-quality non-prescription sunglasses.

While you can wear prescription sunglasses indoors, it's not recommended for extended periods as the dark tint can strain your eyes in low light conditions. Consider photochromic lenses that automatically lighten indoors, or keep a separate pair of clear prescription glasses for indoor use.

Clinical data does not support the idea of damaging your eyes by staring through glasses with an incorrect prescription or pupillary distance configuration. However, some people may suffer from headaches, dizziness, double vision, or vertigo (particularly those with more significant corrections). With a new prescription, you may need an acclimation period - up to three weeks for first-time progressive wearers, but usually less than a day.

While glasses may give some protection against COVID-19, the shielded region of the eye is the only protected area. The virus can still enter your eyes through the exposed sides, tops, and bottoms of your glasses. According to CDC, you should take all necessary steps to avoid touching your eyes. The Ziena eyeglasses became the top brand for people working in the medical care industry with a magnetic eyecup acting as a moisture seal.

At Heavyglare Eyewear, we do sell safety goggles and safety glasses. Depending on your work, there are many different types of safety glasses available.

Rinse dust first, then use lens cleaner and a microfiber cloth—no paper products or harsh chemicals. Be sure your lenses are free of any grit before cleaning. Always use a cleaning cloth, not your t-shirt. You can launder cleaning cloths, but don't use fabric softener as it will smudge the lenses. Frames are covered by the brand's warranty; our premium AR options include a manufacturer warranty against defects.

Keep your eyeglasses in good condition by following these tips:

• Instead of buying new frames every time your prescription changes, ask for fresh lenses placed in the existing frames.
• A spring hinge allows the temples to bend slightly outward without damaging the spectacles.
• Lenses should be coated with a premium anti-reflective coating with hydrophobic and oleophobic properties.
• Follow the care recommendations provided to prevent damage to anti-reflective coating.

With proper care, prescription sunglasses can last 2-3 years or more. The lifespan depends on usage frequency, care quality, and lens coatings. Prescription changes, frame damage, or significant scratches may require replacement sooner. Regular maintenance and protective storage significantly extend their life.

Minor scratches on coated lenses often cannot be repaired and may require lens replacement. To prevent scratches, always use a microfiber cloth, rinse off debris before cleaning, and store glasses in a protective case. Deep scratches that affect vision should be addressed immediately with lens replacement.

Most orders ship in 10–14 business days depending on lens complexity and frame availability. We'll keep you updated at each step.

Yes! Once your order is placed, you'll receive email updates at each stage: prescription verification, lens manufacturing, quality control, and shipping. You'll get a tracking number once your glasses ship so you can monitor delivery progress.

Prescription lenses are custom-made and non-refundable, but we offer a one-time lens remake to get things right. Non-prescription items follow our standard 30-day return policy for unused products.

We want you to love your prescription sunglasses! If you're experiencing issues with vision clarity, fit, or comfort, contact us within 30 days. While prescription lenses can't be refunded, we offer one free remake to ensure your satisfaction. Our opticians will work with you to identify and resolve any problems.

Yes — HSA/FSA cards are typically accepted for Rx eyewear. For vision insurance, Heavyglare Eyewear is an out-of-network provider for most vision insurance plans. You can submit your purchase for reimbursement by completing the Out-of-Network Reimbursement Form, attaching your itemized receipt, and submitting to your vision insurance company.

You can bring in your current prescription to have it filled at our opticians; however, we do not provide eye examinations.
