HYDROTACGläser für Weitsichtigkeit/Gläser zusätzliche Abnehmbare/Gläser-Sonnenbrille Radfahren Maske Fischerei

Buenisimos

Muy contento, hacen su función, ahora veo mis datos del gps cuando voy en bicicleta.

Una volta ritagliate con delle forbici alla misura corretta per l'occhiale funzionano benissimo. Sono lenti da presbite per cui permettono di vedere bene gli strumenti e il cellulare. Aderiscono perfettamente alla lente dell'occhiale e non si staccano nemmeno quando pulisco le lenti.Ottimo prodotto che uso da anni (questo è il secondo paio ), le consiglio vivamente

These are working well in my SCUBA mask. I bought +3 to be able to read the small print on my dive computer. Once I cut them to shape, aligned them and adhered them, I found they did allow me to read the small print and did not noticeably interfere with my normal distance vision.The photos show where I trimmed these to fit my lenses. Trimming was vital to getting them where I needed to see through them properly. They trim easily with sharp scissors. Hints on installation: dry fit them and mark them with marker to trim prior to installation. Make sure they are aligned vertically with your eye but set below your eye. I found it easiest to submerge the mask and lens in water then position the lens and press it on, all while underwater, that way no chance for air trapped.The lenses are flexible but not infinitely flexible. They would not work on a flat mask or extraordinarily curved mask. Mine were 5.5 and 6.5 and the 6.5 had more difficulty trapping air when I tried to adhere above water (thus the underwater adhere technique.)I had read posts complaining about them not adhering well so after they were dried for 36 hours I ran a few tests. Results:- I washed them with: soap, salt water, mask defog, fresh water, pool water, and saliva. They stayed adhered and in position- I dove with the mask and cleared it many times. I even pulled it clear off and wiped it inside with my fingers (underwater). They stayed adhered and in position.- I left the mask in full sun for a few hours. No noticeable effect.- I swam for 1.5 Km to see if they would fog up differently than the mask itself. They did not fog any differently.Bottom line is I would recommend these for use in a prescription SCUBA mask to create bi-focal mask.
