Question 1

When do most people start needing reading glasses?

Accepted Answer

Most people develop presbyopia between 40–45. By age 55 the typical reading add stabilizes at +1.50 to +2.50 diopters. Tell-tale signs: holding your phone farther away than before, eye strain reading menus, or needing brighter light for fine print.

Question 2

How do I estimate my reading power without a clinic visit?

Accepted Answer

Rule of thumb by age: 40 ≈ +1.00, 45 ≈ +1.50, 50 ≈ +2.00, 55 ≈ +2.25, 60 ≈ +2.50. Use our printable near-vision chart at /help or the camera-based PD tool at /measure-pd. We still recommend a professional eye exam every 1–2 years — the prescription drifts.

Question 3

Progressive vs reading lenses: what's the difference?

Accepted Answer

Single-vision reading lenses have one power across the whole lens — only good for 30–40cm focal range. Progressive lenses seamlessly blend distance (top), intermediate ~60cm (middle), and reading (bottom) in a single lens. Add +$89 for progressive at lool. Pick progressive if you switch distances often during the day.

Question 4

How long does it take to adapt to progressive lenses?

Accepted Answer

About 80% of wearers fully adapt within 1–2 weeks. The first 3 days you may feel mild swim when walking or descending stairs — turn your head, not just your eyes, toward what you want to focus on. If you're still uncomfortable after 3 weeks, we'll exchange to single-vision reading lenses or refund — your choice.

Question 5

What are bifocals and does lool sell them?

Accepted Answer

Bifocals split the lens into a distance section on top and a reading section on the bottom, with a visible line between them. lool does not sell bifocals — we offer progressives (smooth blend, no visible line) and single-vision instead, because progressives look more modern and feel more natural.

Question 6

Is blue-light coating actually worth the extra cost?

Accepted Answer

For people with 6+ hours of daily screen time who are 40+, blue-light filtering can reduce digital eye strain and pre-sleep melatonin suppression. lool's blue-light coating is +$12 and blocks ~35% of 380–450nm high-energy blue light. The AAO states there's no evidence blue light damages retinas, but many users report easier sleep — it's a comfort feature, not a medical necessity.

Question 7

Which lens index should I pick: 1.56, 1.61, or 1.67?

Accepted Answer

Higher index = thinner, lighter lens. 1.56 (free, standard) fits prescriptions within ±2.00. 1.61 (+$20) fits ±2.00 to ±5.00. 1.67 (+$45) for ±5.00 and beyond, or anyone who wants the slimmest profile. Most reading-glasses users at +1.00 to +2.50 don't need to upgrade — 1.56 is fine.

Question 8

Can I add polarization or photochromic to reading glasses?

Accepted Answer

Yes. lool coatings stack: blue-light (+$12), UV (+$8), anti-reflective (+$10), scratch resistance (+$6). For photochromic (transitions) or polarized, pick the corresponding option in the lens flow. Note: a single lens can take up to 3 coatings before optical clarity degrades — pick the most useful for your lifestyle.

Question 9

Do I need glasses if my prescription is mild?

Accepted Answer

If your uncorrected vision is 20/25 or better and you don't squint or get headaches, you can usually skip glasses. But for driving, sustained screen work over 4 hours, or scoreboard-distance viewing, glasses help. lool single-vision lenses cover -0.75 to -10.00 at no extra charge, with no edge distortion within 10cm of center.

Question 10

Do myopia-control lenses for teens actually work?

Accepted Answer

Multi-zone myopia-control lenses (DIMS, HALT) slow child myopia progression by 30–60% in clinical trials (IMI 2021 review). They're for kids 6–16 whose prescription worsens by ≥0.50 diopter per year. lool offers these via custom admin flow — not yet on the standard checkout. Email hello@lool.work for a quote.

Question 11

Can I upgrade single-vision to progressive after I've ordered?

Accepted Answer

Yes — within 30 days, mail us back the frames and we'll re-cut progressives. No labor fee, you just pay the +$89 lens upgrade. If your frame is also damaged, the new lenses inherit the original 1-year warranty.

Question 12

Can I order if my prescription is over -6.00?

Accepted Answer

Yes. lool single-vision goes to -10.00 sphere, -4.00 cylinder (astigmatism), +3.50 add. Above -5.00 we recommend 1.67 index (+$45) so the lenses don't get too thick. Upload your prescription at /account during checkout — our lab double-checks before crafting.

Question 13

Do I need to specify astigmatism separately?

Accepted Answer

Yes — your CYL (cylinder power) and AXIS (0–180°) values must be entered or uploaded. lool's standard checkout doesn't ask for prism — if your prescription specifies prism correction, upload the full Rx at /account and we'll follow up manually.

Question 14

How do I know if a frame size will fit me?

Accepted Answer

The three numbers stamped on a frame mean: lens width mm – bridge width mm – temple length mm (e.g. 52-18-145). Ideal fit: lens width ≈ your PD/2 + 4mm; temple length 140–150mm fits most adults. Every lool PDP shows all three plus Frame Width = lens×2 + bridge + 5mm.

Question 15

Round, square, heart-shaped face: which frame works?

Accepted Answer

Rule of thumb: round face → angular (square/rectangular) frames add definition; square face → round/oval frames soften the jaw; heart-shaped (wide forehead, narrow chin) → aviator or bottom-heavy frames balance proportion; oval is a wildcard — almost anything works. lool stocks 9 shapes; try the interactive tool at /find-your-fit.

Question 16

What frames work for low nose bridges or Asian fit?

Accepted Answer

Look for low bridge fit or bridge width ≥18mm, ideally with adjustable silicone nosepads so the frame won't slip or leave marks on the cheekbones. About 30% of lool's acetate frames are low-bridge-optimized; the PDP Bridge Fit field shows either Universal Fit or Low Bridge Fit.

Question 17

Titanium vs TR90 vs acetate: which is best?

Accepted Answer

Titanium: lightest (6–10g), corrosion-resistant, premium price — best for refined business looks. TR90: ultralight engineering plastic (8–14g), flexible without breaking — best for sport, kids. Acetate: richest colors and patterns (tortoise, translucent), 16–22g, designer feel for casual everyday wear. lool stocks all three.

Question 18

Can I virtually try on frames? How accurate is it?

Accepted Answer

Yes — visit /try-on and enable your webcam for live preview. We use MediaPipe FaceMesh (468 face landmarks) to anchor frames to your nose bridge and temples; proportions are accurate to ~±5%. Color and reflection realism depend on your room lighting — natural daylight gives the truest preview.

Question 19

Is there a frame warranty? What if it breaks?

Accepted Answer

lool covers manufacturing defects (loose hinges, coating peel, breakage at the joint) for 1 year. Accidental damage (drops, sat on) isn't covered, but in the first 30 days we offer a 50% discount on replacement. We don't currently sell extended warranties or scratch insurance.

Question 20

What prescription data do I need to order?

Accepted Answer

Myopia / hyperopia: sphere (SPH) + cylinder (CYL) + axis + PD (pupillary distance, 54–78mm typical). Reading: ADD power (+0.75 to +3.50) + PD. You can either fill the form or upload a photo of your prescription at /account — our team verifies it manually within 24 hours.

Question 21

How do I measure my PD if I don't have a clinic record?

Accepted Answer

Three options: (1) Mirror method: stand against a wall, close your right eye, ruler-measure from your left pupil to the bridge center, then mirror. (2) Use lool's /measure-pd tool — webcam + credit card as a scale reference auto-measures. (3) Have a friend hold a ruler across your eyes. Adult PD range 54–78mm, average 63mm. ±2mm error is fine.

Question 22

Is my old prescription still valid?

Accepted Answer

lool accepts prescriptions up to 2 years old. Beyond that we recommend re-checking — your prescription may have drifted by ±0.50 or more. We'll still craft to an older Rx if you confirm, but discomfort due to outdated power isn't refundable (it's not a lens defect).

Question 23

How long from order to delivery?

Accepted Answer

US: 5–8 business days. Europe: 7–10. Canada/Mexico: 6–9. Japan/Korea/Singapore: 8–11. Rest of world: 10–14. These windows include 3–5 days for lens crafting. Frame-only orders ship 1–2 days faster since there's no lens cutting.

Question 24

Can I rush my order?

Accepted Answer

US: +$25 upgrades to 2–3 day DHL Express; order before 11am ET on a weekday. International: +$45 to +$80 depending on country — email hello@lool.work within 24 hours of ordering. We can't compress lens crafting below 48 hours — that's a hard limit from the optical lab.

Question 25

What payment methods do you accept?

Accepted Answer

Credit cards (Visa / Mastercard / Amex / JCB), Apple Pay, Google Pay, and local payment methods shown by Stripe for your region. All transactions are processed by Stripe over HTTPS, PCI-DSS Level 1 compliant.

Question 26

Is shipping really free worldwide?

Accepted Answer

Orders ≥$30: free worldwide shipping. Below $30: +$4.99 US / +$9.99 international. For US, Canada, EU, UK, Japan, Australia, Singapore, Hong Kong — duties and VAT are pre-paid by lool (DDP), so customs won't bill you on delivery.

Question 27

Are custom lenses covered by 30-day returns?

Accepted Answer

Yes — even custom-cut prescription lenses are covered by our 30-day satisfaction guarantee. We pay return shipping both ways. Full refund hits your original payment method within 5–10 business days. Frame must be unscratched and in original packaging.

Question 28

What if the lens prescription feels wrong?

Accepted Answer

Email hello@lool.work with your prescription and symptoms. If we made an error (axis off by ≥5°, power off by ≥0.25), we'll re-cut for free and cover shipping. If the original prescription itself isn't right for you, $30 lens-replacement fee or full refund for a different style.

Question 29

What if the frame breaks or the hinge loosens?

Accepted Answer

Manufacturing defects within 1 year: free replacement (just mail back the broken pair). After 1 year or accidental damage: 50% discount on a same-style replacement (frame only, lenses extra). For minor hinge loosening, send it back for free re-tightening — or any local optical shop can fix it in 5 minutes.

Question 30

Can I track my order? Do I need an account?

Accepted Answer

No account needed. After ordering, you'll get an email with a tracking number. Visit /account, enter your email, and we'll send a 6-digit OTP code (valid 10 minutes, resendable) — once verified, you see your full order history. lool is passwordless by design.

Question 31

Can I talk to a real person?

Accepted Answer

Yes — email hello@lool.work, real humans reply within 24 hours (Beijing + San Francisco rotation, average 4 hours). For complex cases (prescription issues, returns, bulk orders), reply with schedule call and we'll set up a 15-min video call. No phone hotline currently.
