The Two Numbers You Need First

Firmoo requires your prescription and your pupillary distance (PD). The prescription comes from your optician and is worth having in front of you rather than from memory — sphere, cylinder and axis all matter, and a transposed sign produces glasses you cannot wear.

PD is the distance between your pupils, and it is the measurement most often missing from a prescription because opticians do not always print it. It decides where the optical centre of each lens sits. Get it wrong and the lenses will be technically correct and still give you eye strain or headaches. Ask your optician for it, or measure carefully — it is the one number worth double-checking.

Choosing Lenses and Coatings

The frame is the visible decision; the lens is the one you live with. Firmoo offers blue light blocking, progressive, photochromic and Transitions branded lenses, plus its own Goldora lenses.

A short guide: blue light filtering suits long screen days. Photochromic or Transitions lenses darken outdoors, which replaces a second pair of prescription sunglasses — often the cheapest way to end up with both. Progressives handle distance and reading in one lens but need accurate measurements, so they are the least forgiving choice to buy online if your PD is uncertain. If you want sun cover without progressive complexity, clip-ons are the low-risk option.

Getting the Frame Size Right

There is no virtual try-on, but there is a Quick Frame Finder and video guidance for matching frames to face shape. The more reliable method is to measure a pair you already own and like: the frame dimensions are usually printed on the inside of the arm, and matching those numbers gets you closer than judging from a photograph.

The 60-day return and exchange window is generous by eyewear standards, which makes trying an unfamiliar shape far less of a gamble.

How Frame Measurements Work

Printed inside the arm of most glasses is a set of numbers like 52-18-140. They are, in order, the lens width, the bridge width and the arm length, all in millimetres. Matching those to a pair that already fits is far more reliable than judging scale from a product photograph, where every frame is shown at the same size.

Bridge width is the one that decides comfort. Too narrow and the frame pinches; too wide and it slides down. If you are between options on lens width, err smaller for a lighter feel and larger if you want more coverage or are ordering photochromic lenses for sun use.

When Two Cheap Pairs Beat One Good Pair

At these prices the usual logic inverts. Rather than buying one pair with every coating, it is often better to buy two simpler pairs — one clear for screens and driving, one tinted or photochromic for outdoors. You get a spare, which matters if glasses are not optional for you, and the buy-one-get-one offer is built for exactly this.

Looking After Cheap Frames

The habits that ruin glasses are the same at any price. Clean lenses with a microfibre cloth and water rather than a shirt tail, which grinds dust across the coating, and take them off with both hands so the arms do not splay. Store them in a case rather than face down. At these prices a replacement is affordable, but a pair that lasts two years instead of six months is a better saving than any code.
