Of course, when visitors first arrive at your site and start reading your copy, they probably do not know you and have no reason to trust you. That is why it is so crucial to build your credibility. You MUST explain why you are qualified to help them or solve their problem. That does not necessarily mean official qualifications. It may simple be that you have experience the problem that brought them to your site in the first place, and you found a solution to the problem that you want to share with them! AND you must show that you are just like them. A great way to accomplish this is by telling a story!

How do blue light blocking lenses work?

Hello, I'm Dr. Adam Rosa with North Coast Optometry and a question my patients ask me all the time is "how do blue light blocking lenses work?"

Blue light blocking lenses function by putting a thin coating on the front side of the lens that reflects certain types of blue light while allowing other colors to pass through the lens on hindered. 

This creates a saving effect that protects our retina, but maintains good color quality.

Other types of blue light blocking lenses use a yellow tinted lens that absorbs the blue light rather than reflecting it backwards. However, those types of yellow tinted lenses obviously create a yellow tinge to our vision.
