Smart Specs Check

Will my prescription work in these smart glasses?

Type the numbers from your prescription card. We compare them, in your browser, against the lens range each manufacturer publishes for 14 smart glasses, then show whether each pair is on sale where you live.

Private by design. Nothing you type leaves this page: no form submission, no request, no analytics on the values. How that works.

Your distance prescription

Signed dioptres in 0.25 steps, exactly as printed. Leave CYL blank if your card has none. Plus-cylinder cards are converted for you.

SPHCYLAXIS

Axis is needed to order lenses, not to check a range. One eye only? Fill in that eye and leave the other blank.

Optional extras

Only on varifocal or bifocal cards.

Warns only; few makers publish a range.

Where will you buy?

Prescription ranges and prices differ by country, so results are per market.

How the result is worked out

  1. Normalise. A plus-cylinder card is transposed to minus-cylinder form (SPH + CYL, CYL sign flipped, axis rotated 90°). We show you the converted line.
  2. Apply the maker's own arithmetic. Meta, Snap and some lens partners publish a total power limit (SPH + CYL). Even, Viture, Halliday, Rokid and Solos publish SPH and CYL separately. The two are never compared across.
  3. Test every published route for your country: lenses glazed by the maker, an optician partner, a clip-in insert or a built-in dial. Each has its own limit, source link and verified date.
  4. Rank. Within the maker's own range first, then partner, insert and dial routes, then "range not published", then outside the range. Sources older than 45 days are flagged; older than 90 days drop out of the top tier.

The full rules, the eight test cases the code must pass, and the update schedule are on the methodology page. Every figure links to its source on the sources page.

This tool checks whether your prescription falls inside the range each manufacturer publishes. It is not optical advice and does not replace a dispensing optician. UK law requires that spectacles for anyone under 16, or anyone registered sight impaired or severely sight impaired, are dispensed by or under the supervision of a registered practitioner, and that prescriptions are less than two years old.
