Enhanced my vision
Exactly as described and works perfectly. Prompt delivery and a quality product. This definitely helped with vision.

Works with limitations
It works in terms of reducing the double vision around pictures caused by cataracts. But parts of the TV picture are blocked by the glasses so you need to move your eyes around to see those parts.

seek medical help before just buying this product
Works perfectly, but please consult an optician first

Holes are too big
We bought a pair of pinhole glasses about 20 years ago for my daughter and they worked to a certain extent although she wasn't able to stick with them. I bought these as I thought they might work as a cheap option for kayaking glasses but the holes are far too large. This is a shame as the glasses are otherwise grand. To be pinhole glasses the holes would need to be far smaller, these ones just make my eyes see double.

Not adult, teeneager / young adult
Suitable for a pre-teen to young adult but not adult, the bridge is too narrow and doesn't accomodate any of the adults I have had try them on...

Very good
It was a bit of a shock initially. But after a while I got used to them. It’s like looking at the world through a confessional grill. The more I focus on the words on the page, rather on the glasses, the better it is. My eyes are getting better. I’m also doing exercises from the book ‘You Don’t Need Your Glasses Or Contacts’ by Dr John Dewitt.

bon marche
Apres avoir cherche sur le Net des lunettes a trous, dont les prix allaient de 50 a 15 euros, pour la plupart, j'ai trouve sur le Net cette formule, avec des commentaires plus que satisfaisants des usagers, pour le prix de 6 euros, tout au plus, et je me suis dit que, comparativement, je ne trouvais dans les descriptifs aucune justification qui faisait que le prix varia de 20, 30 ou plus euros, je me suis donc rabattu sur ce qui était de meilleur marche, et j'en suis fort satisfait

Comprati per la seconda volta
Ottimo occhiale per allenare il proprio campo visivo, mi piacciono questo tipo di modelli perché hanno i fori che si adattano perfettamente alla mia visuale e le lenti sono molto vicine all'occhio pertanto si riesce avere una visione abbastanza uniforme.tuttavia l'occhiale seppur economico è molto delicato e la fattura è veramente scarsa.ma mi sono piaciuti così tanto che ne ho comprato un altro paio di riserva.da usare sostanzialmente di tanto in tanto per rafforzare la vista accompagnati da esercizi per i muscoli degli occhi e della retina. Mi raccomando questi esercizi fateli in concomitanza di libri legati a questo tema. Migliorare la vista con gli esercizzi metodo Bates

Bin positiv überrascht....
Habe mir die Brille zugelegt, da ich mich absolut weigere mir eine richtige Brille zu kaufen und immer noch hoffe, dass ich eine Möglichkeit finden werde, damit meine Sehkraft sich nicht verschlechtert. Durch unseren Physiotherapeuten sind wir auf diese Rasterbrillen gestossen und bei 8 Euro kann man nicht viel kaputt machen dachten wir und haben sie bestellt. Fazit nach 14 Tagen: Wenn ich morgens zu bald aufwache, dann lese ich noch gerne im Bett. Normalerweise sehe ich dann danach einiges schlechter und verschwommen. Habe es nun schon einige Male mit der Rasterbrille ausprobiert. Das lesen gestaltet sich zwar etwas schwieriger und das Sichtfeld ist durch die kleinen Löcher eingeschränkt aber egal, ich habe danach keine Sehprobleme mehr wie vorher ohne Rasterbrille. Das hat mich absolut überrascht und begeistert !! Die Brille selbst ist gut verarbeitet und sitzt auch gut. Es gibt auch keine Mängel bei der Verarbeitung Werde die Brille natürlich weiterhin testen und werde dann nach ein paar Monaten nochmal ein Fazit abgeben... Es gibt bestimmt Sehschwächen, wo diese Brillen nicht helfen aber ich kann diese Brillen jederzeit mit gutem Gewissen weiterempfehlen. Selbst mein Mann (+2,5) ist überzeugt und würde bestimmt etwas verbessern wenn er sie regelmäßig benutzen würde.... Es muss also eine 2. her.

Helps you focusing
Both of my eyes are -1, I usually use these glasses to read text/film subtitles which are far away from me and it works really well. Keep in mind that it can cause a slight headache if you are constantly using it for hours.

It functions effectively for me, potential as an eye trainer remains to be explored.
It functions effectively for me, serving as a specifications tool with a negative power aspect. need good light to work well, However its potential as an eye trainer remains to be explored.
