Buying Glasses

Buying glasses is about more than picking a frame you like — it's about fit, prescription accuracy, and lens choices that actually serve how you live. Start with a current, valid prescription from a licensed eye doctor. From there, your optician measures your pupillary distance (PD), helps you choose a frame that suits your face and lifestyle, and recommends lens materials and coatings based on your prescription strength and daily habits.

The biggest mistake people make is buying online without an in-person fitting. Frame fit and PD accuracy directly affect how well your glasses work — get either wrong and you'll deal with headaches, eye strain, or distorted vision, even with a perfect prescription. Buying locally means a real person checks all of this before you walk out the door.

Budget-wise, expect a range depending on frame brand, lens material, and coatings — single vision glasses with basic coatings sit at the affordable end, while progressives with high-index lenses and premium coatings cost more. Insurance, FSA/HSA funds, and promotions (like our Give & Receive frame donation discount) can all help offset cost.

Bottom line: bring a valid prescription, get measured in person, and work with someone who will tell you honestly what you need — not just what's most expensive. See our full Buying Glasses FAQ →

Progressive Lenses

Progressive lenses are no-line multifocals — they blend distance, intermediate, and near vision into one lens, with no visible line like old-school bifocals. Most people start needing them in their 40s, when natural near-focusing ability (called presbyopia) begins to decline.

The lens is divided into invisible zones: the top for distance, the middle for intermediate tasks like computer work, and the bottom for reading. Your eyes naturally shift through these zones as you look up, ahead, or down — but it takes the brain a little time to learn this. Most people adjust within one to two weeks. Some peripheral blur or a "swimmy" feeling at the edges during that window is completely normal.

Quality matters a lot here. Higher-end progressive designs have wider, more comfortable viewing zones and less peripheral distortion than basic versions. If you spend a lot of time at a computer, ask about computer progressives — a specialized version optimized for screen distance rather than driving distance.

Fit and measurement precision matter more for progressives than any other lens type, since the zones are calibrated to exact placement on your face. This is one category where a skilled, in-person optician makes a real difference in how well your glasses actually work day to day.

Prescription Sunglasses

Prescription sunglasses combine your vision correction with UV and glare protection — meaning you don't have to choose between seeing clearly and protecting your eyes outdoors. Any frame in our sunglass collection can be fit with prescription lenses.

UV protection should be non-negotiable: look for lenses rated UV400, which blocks both UVA and UVB rays. This matters year-round, not just summer — UV exposure contributes to cataracts and other long-term eye damage regardless of season.

Polarized lenses are worth the upgrade for most people. Regular tinted lenses simply reduce overall brightness, but polarized lenses block horizontally reflected glare — the kind that bounces off roads, water, and car hoods. If you drive often, fish, or spend time near water, the difference is noticeable.

Photochromic (Transitions-style) lenses are another popular option: they're clear indoors and darken automatically in sunlight, which is convenient if you don't want to carry two pairs of glasses. They're a great middle ground for people who go in and out throughout the day.

Whatever you choose, make sure your prescription sunglasses are properly fitted just like your everyday glasses — pupillary distance and frame alignment matter here too.

Children's Eyewear

Kids' eyewear has different priorities than adult eyewear: durability, safety, and a fit that survives an active school day. The American Optometric Association recommends a first comprehensive eye exam between 6 and 12 months old, another between ages 3 and 5, and then annual exams once school starts. Vision problems can quietly affect learning, so catching issues early matters.

For lens material, polycarbonate is the standard recommendation for nearly every child's prescription. It's impact-resistant, lightweight, thin, and has built-in UV protection — a meaningful safety upgrade over standard plastic lenses for active kids.

Frame selection matters just as much as lens choice. Look for flexible hinges and spring temples that can bend without snapping, since kids are tough on glasses. And here's the most important tip: let your child help pick the frame. Kids consistently wear glasses they chose themselves far more reliably than glasses picked for them — comfort and confidence both play a role.

If your child squints at the board, sits unusually close to screens, or a teacher mentions vision concerns, don't wait for the annual exam — schedule one sooner. Uncorrected vision problems can have a real impact on a child's classroom performance.

Lens Replacement

If you have frames you love but your prescription has changed, lens replacement lets you keep the frame and simply update what's inside it. The frame needs to be assessed first — hinges, structural integrity, and overall condition all matter, since some frames are too worn to safely hold new lenses.

One common misconception: you generally cannot move existing lenses into a different frame. Lenses are cut to fit the exact shape and size of the frame they're made for, so transferring them to a new frame almost never works unless the frames are nearly identical. The better approach is always to have new lenses cut specifically for the new frame.

Lens replacement is a great option when your prescription changes but your frame is still in great shape, when you're upgrading lens features (adding anti-reflective coating, blue light filtering, or switching to progressives), or when you simply want to modernize an old favorite pair without buying an entirely new frame.

Turnaround time depends on the lens type and whether the prescription is in stock. Standard single-vision replacements are often same-day; more complex prescriptions may take longer.

Vision Insurance

Vision insurance typically covers some combination of eye exams, a frame allowance, and lens costs, though exact coverage varies significantly by plan. Common features include an annual or biennial exam allowance, a set dollar amount or percentage off frames, and either flat-rate or tiered pricing on lens upgrades like progressives or anti-reflective coating.

The most important first step is simply bringing your insurance card in before you start shopping. A good optical shop will verify your benefits up front and tell you exactly what's covered and what you'll pay out of pocket — there should be no surprises at checkout.

If you don't have vision insurance, you're not out of options. Many people pay out of pocket and still find affordable choices, especially when mixing frame price points with lens upgrades only where they matter most. FSA and HSA funds can also be used for prescription glasses and lenses, which is an easy way to reduce your effective cost using pre-tax dollars.

One tip: insurance allowances often reset annually, so if you're due for new glasses near the end of your plan year, using your benefits before they expire can mean real savings.

Same-Day Glasses

Same-day glasses are possible when the optical shop has its own in-house lab and the right stock lenses on hand for your prescription. Instead of sending your order to an outside lab and waiting days, the lenses are cut and mounted right on-site — often in about an hour for standard single-vision prescriptions.

Not every prescription qualifies for same-day turnaround. High-powered prescriptions, certain progressive designs, and specialty lens materials sometimes require ordering from an outside supplier, which adds time. The best way to know if your prescription qualifies is simply to ask — bring your prescription in or call ahead, and a good optical shop will check inventory and give you a clear answer before you commit.

Same-day service is especially valuable if you've broken your only pair, you're traveling soon, or you just don't want to wait around for something you need to see clearly every day. It also tends to reflect a shop's quality control — when the same team that measures you also fabricates your lenses, there's more oversight from start to finish than when work is outsourced to a remote facility.

Choosing Frames

The right frame comes down to three things: face shape, prescription strength, and lifestyle. Face shape guides are a helpful starting point — angular frames like rectangles and squares tend to complement round faces by adding definition, while softer, rounder frames often balance out angular or square face shapes. But guides are general starting points, not strict rules — the only way to really know is to try frames on.

Prescription strength matters more than people expect. Higher prescriptions tend to look and feel better in smaller frames paired with high-index lens materials, which minimizes lens thickness and weight. If you have a strong prescription, mention it before falling in love with an oversized frame style.

Lifestyle should guide material and durability choices. Active people benefit from flexible, impact-resistant frames. Office workers might prioritize lightweight comfort for all-day wear. Frequent travelers might want something more compact and durable for a bag or case.

Finally, fit is non-negotiable regardless of style. Frames should sit level on your face, rest comfortably on your nose without pinching, and not slide down or dig in behind your ears. A great-looking frame that doesn't fit well will never feel as good as a slightly different style that's properly adjusted to your face. See our full Face Shape Guide →
