@Matt: After playing ps4 for over 3hrs I start getting headache and eyes start to burn, but with these playing at 4hr still haven't gotten headaches or burning red eyes. I had to order a bigger pair and give these to my wife, and she loves them.
@わんいいなさい: デザインがとても可愛いくて気に入ってます。一日中PCとスマホを使用するので眼精疲労がひどかったのですが、これをかけると疲れにくいです。軽くて長時間かけても耳が痛くなることもありませんでした.@Andrea Guastaferro: In quanto passo molte ore al pc ho deciso di fare un regalo alla mia vista e prendere questi occhiali. Gli effetti si notano subito: occhi molto meno affaticati a parità di tempo speso davanti lo schermo e se abbinato ad un a pausa ogni ora di utilizzo si risparmia pure sull'oculista ;)@Jérémy F: Livraison ultra rapide , et lunettes exactement comme sur la photo , avec la lingette et la jolie pochette , après une journée d'utilisation sur l'ordinateur , pas de mal de tête . @Voßschulte: Die Computer Brille passt perfekt zu meinem Gesicht und sitzt perfekt weil sie nicht rutscht und bequem ist. Festes Brillenetui das die Brille sicher schütz. Weiter zu empfehlen.@Mariola M: Llevo ya un tiempo usándolas y desde luego noto una gran diferencia a la hora de reducir el nerviosismo y dormir mejor. ¡Recomendable!

If your doctor did not include your pupillary distance (PD) in the prescription, use one of these two easy methods to determine your PD.
What is Pupillary Distance?
Pupillary distance (PD) measures the space between the pupils of your eyes. Knowing this measurement is important to make sure your eyes match up with the optical center of your lenses, so you can see well with the glasses.
The average adult’s PD is between 54-74; kids' are between 43-54.
How to Measure Your PD?
Check out the graphic below for more information and to learn how your friend can help you measure your PD.
Armed with your PD and prescription, you can shop at Cyxus to find your perfect pair of glasses.
1. Have your friend place a millimeter ruler across your brow.
2. Have them align the ruler's zero to the center of your right pupil.
3. With the ruler straight and flat, have them record the distance from the center of your left pupil.
4. This distance is your PD.
1. Stand or sit about 20 cm (about 8 inches) away from a mirror.
2. Hold a millimeter ruler above your eyes and flat against your brow. Close your right eye and align the ruler's zero to the center of your left pupil.
3. Without moving the ruler, open your left eye and close your right eye. The distance measured to the center of your right pupil is your PD.
4. Repeat 2-3 times to ensure you have an accurate measurement.
