    Distorted Vision with Prescription Sunglasses

    I recently bought a pair of Rudy Project Rydon sunglasses and am having a problem with the RX inserts. My vision with the inserts is very distorted. It's similar to looking through a round fish bowl or a car's passenger side mirror (objects in mirror are closer than they appear) The optic shop that cut the lenses say it's due to the extreme curvature of the RX frames. They say the problem is common with wrap style sunglasses with RX lenses and I'll just have to get used to it. The curvature explanation sounds reasonable except that the left side is not as bad as the right, which leads me to believe that curvature can't be the total problem. Has anyone experienced this with prescription sunglasses? Is this something that I just have to accept or is the Tech at the optics shop just not doing something correctly? My prescription is -3.75 and RP says that the inserts are recommended for up to -4.0.

    Thank you!

    I had the exact same problem. I ordered prescription lenses from Rudy as well, not for cycling but because I needed them for softball/golf. Everything was distorted, I couldn't even wear them to play golf because I would get sick to my stomach when I looked down at the ball on the ground. I was told the exact same thing they told you. I decided I didn't need to play softball anymore because of that, and I just bring a good sighted friend to find my golf ball

    When I first got my wrap arounds I experienced an adjustment period. My eye doctor had warned me ahead of time to expect it. The first time I put them on it took about 10 minutes before my brain learned to see through the curvature. The next time took about 5 minutes, the next 2, the next 1, and now no adjustment period is required. Durring the adjustment period I would esperience bluryness or distortion in my periphal vision. Now that I'm used to them I think the RX on my sunglasses is better than on my day to day pair.

    If you've not given them some time on your head, give it a try.

    Anything with inserts is going to be distorted because of the curve of the lenses. Spend the cash and get some RX Oakleys. I have two pairs and they are worth every penny I've spent. The lenses are clear and distortion free. They aren't cheap, but worth it in the long run.

    Bolle's Vigilante and Parole both use an insert that has little "face form" of the insert. That's where the distortion comes from. I have not seen the Rudy Project that you speak of but too much face form, at best always creates some distortion most of the time.

    Can't you wear contacts?

    BTW, I'm an optometrist, if you want more specific answers and you're not comfortable asking them on this forum, shoot me an e-mail.

    no distortion here

    I don't have Rudy Project but I do have a pair of wrap-around prescription sunglasses. I got them done at my local optometrist. He didn't do the lenses. He obtained the lenses from some outside source which, he said, specialized in these types of curved lenses. They work great and I have no distortion. (Sorry, I don't know the company/lens name but your optometrist should be able to find out.)

    As for your problem, I would look at how the RX insert fits into the glasses. Slight changes in angle due to fit or flex would produce the experience of distortion. That is why I went the route of obtaining a pair of prescription sunglasses.

    Thanks for the invite to private email. However, I'll go ahead and ask here because I think it benefits the search feature if someone else has the same question in the future.

    I've worn contacts for 15 years and dont have a problem wearing them on short rides. However, on rides over 4 hours, they tend to dry out. Once Im home and remove them, my vision is blurred for a couple of hours after. This is why I sought an alternative to contacts.

    With the RX inserts, my distant vision when viewed straight ahead is normal. When looking left or right I get the curvature effect. The curvature effect when looking left or right is acutally caused by the eye opposite of the direction Im looking. (when looking right, the left eye views the curvature) When viewing from the center of either lens to the outside edge (toward the ears), the vision is clear and normal. ie: with the left eye, I can look straight ahead and scan to the extreme left with no distorted effect. with the left eye, If I look straight ahead and scan to the right, I immediatly get the distorted, curved vision. Opposite effect with right eye. When looking at arms length I have the effect of items being closer than they appear.

    Is this something that I can get used to with time like Scot_Gore stated? If it seems to strain my eyes or cause headaches, should I simply forget the inserts and continue on whith contacts? (and stew over the wasted money for the next 20years. lol)

    Thank you all for your help!

    I run a pair of Addidas wrap arounds with prescription inserts, no distortion ever from day one. I threw them on at the shop when I picked them up and wore it for the rest of the afternoon, again no distortion or adjustment period for me

    Prescription Lense - Not Inserts Working Great

    I just got a pair of Rudy's with prescription lenses - not the inserts. I'm at -6.25 and while I see a bit of distortion, it is very minor and does not interfere with anything. There is substantial wrap.

    I also got the light sensitive lenses so that I can wear the same lense when it's very early in the morning and it gets a bit darker as the sun gets brighter.

    Very happy with them.

    Re: your inserts, take the whole package to your eye doctor and see if they are centered properly.

    Just checked - my Rudy's are the Kybo which fit smaller faces well. Good information at http://www.rudyprojectusa.com/produc...ses/rxinfo.htm. I'm very pleased.

    Try sportsoptical.com

    Only a very few models of glasses with inserts work with higher Rx. The only ones that are recommended are Rudy Project RB3 and Adidas models like the Evil Eye. Also get the highest index lens you can find together with the roundest and smallest shape.

    Finally use a specialist optician like Bret Hunter at www.sportsoptical.com in Lakewood, CO

    He uses a propietary formula and grinds the lenses to perfection himself. A great guy and cyclist himself.

    He made my Evil Eye Rx and its -7.5 and -6.75. Perfect ... no more distrotion than my regular glasses.

    I agree with Merckx56 - the Oakley prescription sunglasses that I have are the best sunglasses I have ever purchased. I have other regular frame sunglasses that I don't even wear any more because the Oakleys are so much clearer. "You pays your money and takes your chances!". The Oakleys are worth what they charge.

    The problem is that the lenses are not centered properly. Lenses have an optical center and if they are not in the right place then you will have this distortion issue. The optician did not properly follow the directions from Rudy. The optical inserts are designed to help prevent this when done properly with a higher base (curve lense). Take them back and get them to fix the problem, if they say they can't then they don't know what they are doing. You can buy the lenses direct from Rudy ground properly.

    No distortion here

    I use 2 RX insert type glasses:

    Briko Sprinter Klip set
    Rudy Project (RPJ)

    I had Lenscrafters do the RX inserts and they have no distortions. It was as if I was weariing my regular glasses. However, since the inserts are shorter in length than my regular glasses, I do lose some peripheral vision.
