I paid a bit more for thinner lenses to match the style of my frames and added blue light protection. WORTH. My experience was quick, easy and very satisfactory. It took about 2.5 weeks- the quality is professional and the blue light protection actually works quite well. I can see clear as day through my favorite cheap frames. Only constructive criticism I can offer is to improve tracking capabilities to be more akin to Amazon since it does take reasonable time. Thank you Lensabl!
