Contact Lens Suppliers

Is there a contact lens supplier that will.......?
is there a contact lense supplier that will send you color contacts that don't have a prescription that you can try on? So you can see the color for yourself and see if you like it? My eye doctor is being a DOUCHBAG. He always tells me that they don't have color contacts in my script, and i know they do, because i've been ordering them in my script from 1800contacts for years. I asked if I could try on the color contacts and he's says " We'll tackle that with the next appointment." every single time. The reason why I want to try them on first is because I have really dark brown eyes and i know I can't wear freshlook or several other brands because they don't show up on my eyes. But there are several others that are so good they really pop. I just would like to try on the colors to see which looks best All i've ever had is green and grey...Should I just try to find another eye doctor?I just really wonder if there is a website that will send you contacts to try on.

I'm trying to find an online contact lens supplier who goes up to very strong strengths - i.e minus 15!?
My existing opticians has closed down, and they seem to be the only place on this planet that can get very strong lenses.Tesco, Books, Specsavers etc only go up to minus 12 for my eyes any ideas where I might get some from? Either online or offline? Thanks in advance
