ITEM:- uglyfish sunglasses (element frame in black tint, clear, and yellow) with prescription lense insert how much for frame: I paid $150 for the frame, which included the 3 different colours, an elastic headband (open face helmets) 1 hard case, and 2 soft cases to get my presciption lense inserted cost me an extra $198. they arent a curved lense, but close to it. this cost would depend on your prescription. TOTAL COST: $348 i brought the frame at the GP, took the lenses in straight away to get my lense put in. its taken 3 weeks for then to get it back to me, but i finally have my hands on them. its my first pair of sunglasses in 15 years, im used to tinted prescrition lenses, so this is just awesome having such a dark tint, and being able to see at the same time. The prescription lense frame fits onto the padded frame you get with uglyfush glasses, and then attaches to the nosepiece of the frame you want to use, meaning you can use your lense in any of the 3 frames provided. im not used to haveing my lenses so far apart, so it seems a bit funny to have them on at first. its something ill be able to get used to with a bit of time. they seem a little heavy in the front end, again something ill get used to, but its not they they are going to fall off my face first bump or anything, i havent worn them on the bike yet, but i am confident they'll fit snugly under my helmet, and unlike my glasses which have hooked arms, the uglyfish has straight arms.. so no pain trying to get them under the helmet and comfortable and having your ears go all scrunchie. the prescrition lense clip doesnt quite cover your full field of vision inside the frame, but the only parts that arent covered are the extent of your peripheral vision, so you dont realistically lose any FOV through that. the 2 things im having trouble with is the problem with the lenses being so far apart, nad having a wide frame on my face after only having wire frame glasses, somethign some people might already me used to depending on the sorts of glasses they wear. in the end, $350 isnt much different for what you would pay for a set of glasses depending. and for your money you get 3 different tints, and a pair of sunglasses with a prescrition lense. to get a similar item from day oakley who do put prescriptoin lenses into their frames, i think its costs $500 to get the lenses made up and in the frame, that doesnt include the frame. all in all its a good investment IMO and once i get used to them you wont be able to get them off my face this summer. i wont rate them out of 10. ill just say they arent perfect, but they offer a more affordable solution to something us glasses wearing people have had to deal with for a long time, and im not worried or upset about the outlay at all.
