I am 52 and been working in the Ophthalmic Medical business for over 30 years. The website will be a reference site and will be very professional. The logo needs to reflect that with correct color(s) for that target market ( age 40-60)
My site is aimed solely at people involved with the purchase and use of every ophthalmic instrument and associated product. These people are Ophthalmic Eye Surgeons, LASIK docs, Nurses. Hospital buyers.
A logo that will look great on the web, in printed form and a tie in to the site name ophthalmicdata.com Therefore the logo and web address need to be one thing , if that makes sense.
