Hi Evelyn! Thank you so much for your interest on our frame S9811K. For high prescriptions like -8.00, we would not recommend a wire frame as the frame may not be thick enough to hold the lenses. It may result to the lenses being highly-noticeable as the the edges will stick out of the rim. We'd strongly suggest you get a frame made of acetate or plastic as they are strong and are normally thick enough to hold high prescriptions. Please checkout these frames https://www.firmoo.com/z/kids-glasses.html?products_metal=p,mp,sg&page=1 . For any additional concerns, please don't hesitate to call us at 1-855-487-6006 we are currently open between 6:00AM - 6:00PM Pacific time daily. You may also send us a chat and our Live Chat specialists are open 24/7 or email us at service@firmoo.com and you will get a response within 24 hours during weekdays and 24-48 hours on weekends. All the best for you Evelyn! 

Dear Cak, yes. You can choose 'Customize' button when you select lens and then you will find transitions lens under lens options.
