SINGLE VISION LENS REPLACEMENT
Single vision lenses are made for one primary viewing purpose—such as distance, near/reading, or an intermediate/computer range. If your prescription changed, your lenses are scratched, or you want a different material or lens feature, RenewLens can replace the lenses in many compatible frames while you keep the frame you already like.
THE BASICS
Single vision lenses are designed for one primary focal purpose rather than multiple progressive zones. They may be prescribed for distance, near/reading, or a specific intermediate task such as computer work.
Single vision does not mean “simple prescription.” A single vision prescription can still include sphere power, astigmatism correction with cylinder and axis, prism when prescribed, and different powers for the right and left eyes.
What makes the lens “single vision” is that it is intended for one main viewing range, unlike bifocal or progressive lenses that combine more than one focal range in the same lens.
CHOOSE THE VIEWING RANGE
The right choice comes from the prescription and the viewing distance the lenses are meant to support.
Designed primarily for farther-away viewing. They may correct nearsightedness, farsightedness, astigmatism, or a combination depending on the prescription.
Designed for one near working distance. The prescription is optimized for close tasks rather than distance viewing.
Single vision can also be prescribed for a specific intermediate working distance, such as a desktop monitor.
SINGLE VISION VS MULTIFOCAL
UNDERSTANDING THE RX
Your eyeglass prescription may contain several fields. Not every prescription uses every field, and RenewLens uses the information required for the lens order being made.
WHEN TO REPLACE
You do not need to replace a frame simply because the lenses need to change.
If the prescription changed, new lenses can often be made for compatible frames you already own.
Replacing worn lenses can restore the optical surface without replacing a frame that still works well.
You may want a thinner, lighter, more impact-resistant, or otherwise different material where appropriate for the prescription and frame.
New lenses can be ordered with compatible coatings, light-adaptive technology, tint, polarization, or other available options.
LENS MATERIALS
There is no universal best material. The correct choice depends on prescription strength, frame, lens size, thickness goals, durability needs, optical priorities, and budget.
LENS FEATURES & UPGRADES
Single vision describes the focal design. It does not prevent the lens from also using compatible materials, coatings, tint, light-adaptive technology, or sunglass features.
Anti-reflective treatments can reduce surface reflections and may improve lens appearance and visual comfort in certain lighting conditions.
Compatible single vision lenses may be ordered with light-adaptive technology that changes tint with light exposure.
Single vision prescriptions can also be made as compatible polarized sunglass lenses for glare reduction outdoors.
Eligible single vision lenses may be made with tint where the material, prescription, and selected product allow it.
Some lens packages include blue-light filtering features. The exact benefit and product design depend on the option selected.
Lens packages may include hard-coat or other surface treatments intended to improve resistance to everyday wear.
SINGLE-LENS REPLACEMENT
Sometimes, but a one-lens replacement should be reviewed carefully so the new lens is reasonably compatible with the lens that remains.
Matching may involve the prescription, material, coating, tint, thickness, base curve, age, and appearance of the existing lens. Even when the prescription can be made, a visible or optical mismatch may make replacing both lenses the better choice.
Contact RenewLens before ordering a single-lens replacement so the situation can be reviewed.
FRAME COMPATIBILITY
Many full-rim metal and acetate frames can be re-lensed when they are in suitable condition. Specialty construction may require additional review.
HOW IT WORKS
The goal is simple: keep the compatible frame and replace the old lenses with newly made lenses for the prescription and options selected.
Select distance, reading, or another single-vision configuration plus the material and upgrades you want.
Submit the prescription and measurements required for the selected lens and frame.
Pack the frames securely and send them according to the RenewLens shipping instructions.
The replacement lenses are made, edged and installed into compatible frames, then the finished glasses are returned.
COST
Price depends on the prescription, material, frame requirements, coatings, light-adaptive technology, polarization, tint, and other selected upgrades.
Stronger or more complex prescriptions may require different materials or production options.
Standard plastic, polycarbonate, Trivex, and high-index materials have different price and performance characteristics.
Premium anti-reflective coatings, Transitions®, polarization, tint, and other options can change the final total.
Choose the viewing range, material, and lens features you need, then send your compatible frames to RenewLens for replacement.

FREQUENTLY ASKED QUESTIONS
Single vision lenses are made for one primary focal purpose, such as distance, near/reading, or a specific intermediate working distance. They do not combine multiple progressive zones in the same lens.
Yes, many compatible frames can be re-lensed with new single vision lenses if the frame is in suitable condition and works with the prescription, material, and mounting requirements.
No. Single vision lenses can be prescribed for distance, reading/near, or a specific intermediate distance such as computer work.
Yes. A single vision prescription can include cylinder and axis values for astigmatism correction while still being designed for one main viewing range.
Sometimes, but the replacement may need to match the remaining lens in prescription, material, coating, tint, thickness, base curve, age, and appearance. Contact RenewLens before ordering a one-lens replacement.
The best material depends on prescription strength, frame, lens size, thickness goals, durability needs, optical priorities, and budget. Higher index is not automatically better for every prescription.
Yes. Compatible single vision prescriptions may be made in high-index materials such as 1.60, 1.67, or 1.74 when appropriate and available for the selected lens package.
Yes, compatible single vision lenses may be ordered with light-adaptive technology or as polarized prescription sunglass lenses when available for the prescription, material, and frame.
Single vision lenses are designed for one primary focal range. Progressive lenses combine distance, intermediate, and near correction in one lens without a visible bifocal line.
The required measurements depend on the prescription, frame, and lens design. Pupillary distance is commonly used, and additional fitting information may be required for some orders.
Many rimless and semi-rimless frames can be re-lensed, but frame condition, mounting style, lens material, and prescription must be reviewed carefully.
