First-day checklist

When you receive your new eyewear, run a quick five-minute check. Going through these steps now prevents most of the small annoyances people report later:

1. Fit: check behind the ears and at the nose pads. The frame should sit firmly without sliding when you move your head.
2. Vision: book, phone and distant text should be sharp the moment you put the glasses on. A brief "floor tilt" feeling is normal in the first minutes (especially with progressive lenses).
3. Pupil alignment: the lens optical centre should sit directly in front of your pupil (your optician will show you in store). Misalignment causes long-term eye strain.
4. Accessories: original case, microfibre cloth, warranty card and invoice should be in the bag.

If symptoms persist, see a doctor first. Horizontal double vision, ongoing headaches, sudden blurring or loss of vision are not always caused by eyewear. If any of these lasts more than a few days or comes on suddenly, see an eye doctor (ophthalmologist) — having your glasses checked is not a substitute. The guidance on this page is about product care and is not medical advice.

Fit and sizing

If you already own a pair you like, three numbers are printed inside the temple arm (for example 52-20-145): lens width, bridge width and temple length, all in millimetres. Comparing those three numbers is more reliable than re-measuring your face.

• A frame that is too wide lets the nose pads slide, which pushes the lens optical centre away from your pupil.
• A temple arm that is too short presses behind the ear and causes headaches.
• When in doubt, drop into one of our stores — an optician will measure your current frame and tell you the range that fits. The same three measurements appear in the size guide on every product page.

Cleaning

Correct cleaning extends the lens lifespan more than anything else. Incorrect cleaning causes microscopic scratches that build up over months.

Daily

• Use one thing: warm water plus a drop of dish soap. Never use a tissue, kitchen towel or your shirt — paper fibres scratch the coating.
• Rub the lenses gently with your fingertips, then dry with a clean microfibre cloth.
• Carry the microfibre cloth with you. Replace it every 3 months (you can wash it at 40 °C without detergent to extend its life).

Weekly

Oil builds up around the nose pads and behind the ears — weekly cleaning catches it:

1. Place the frame in the sink.
2. Using a soft-bristle toothbrush, scrub the nose pads, hinges and edges of the lenses.
3. Rinse thoroughly, dry with the microfibre cloth.

Never use

• Acetone or alcohol cleaners (they dissolve the anti-fog and water-repellent coatings).
• Paper towels, napkins, newspaper (paper fibres scratch).
• Hot water (it cracks the anti-reflective coating — stick to warm).
• Steam cleaners or the dishwasher (deforms acetate).

Storage

Whenever you take the eyewear off, put it in its case. Hard cases protect against impacts in a bag; soft cases protect against scratches on a nightstand. Pockets, the bottom of a bag and a car dashboard slowly destroy hinges.

• Do not push the frame onto your hair like a headband — hair oil seeps into the frame and loosens the hinges.
• Drop in every 2–3 months for a free screw-tightening at any of our stores.
• Never leave the eyewear in a car in summer — the cabin reaches 70 °C, and acetate softens above 80 °C.

Sport and outdoors

For sport, a silicone strap is recommended. For swimming, use prescription swimming goggles — regular glasses are not resistant to chlorine and prolonged UV. Beach sand causes micro-scratches; if you take the glasses to the beach, keep the case nearby.

Children's eyewear

A child's eyewear needs an in-store check every six months, without exception:

1. Are the nose pads worn?
2. Is the over-ear bend still snug?
3. Is the prescription still right? (in growth years, prescriptions can shift every 3–6 months)

For repair and replacement options on children's frames, visit one of our stores.

Annual general check

Bring the eyewear in once a year to one of our stores for a free general check that includes:

• Screw tightening
• Ultrasonic lens cleaning
• Frame realignment
• Nose-pad replacement (if needed)

The check takes about 15 minutes. No appointment needed — just walk in.

When to re-check your prescription

The intervals below are a general guide; your eye doctor decides the right frequency for you. If you notice a change in your vision, do not wait for the interval to pass.

Age range	Prescription check
5–18	Every year
18–40	Every 2 years
40–60	Every year
60+	Every year (essential)

If your prescription changes, you can keep your existing frame and only pay for new lenses.

Warranty and repair

• 2-year warranty on the frame against manufacturing defects — hinge breakage, frame coating defects and loose screws are repaired free of charge.
• 1-year warranty on lens coatings — if the anti-reflective or hydrophobic coating fails within that period, we replace the lenses free. Lens coatings and frame coatings run to different periods; the details are in the FAQ.
• Accidental damage is not covered by the warranty — drops, crushing and breakage are not manufacturing defects. Call +90 850 220 22 22 anyway and we will go through the repair options with you.
• Emergency repair — call +90 850 220 22 22. Most repairs are completed same-day or next-day.
• For returns and exchanges outside the warranty, see our returns policy (30-day return window).
