There is a marketing buzz word going around right now for contact lenses that you might be hearing about more next year and it is called "HD Optics." If you are like me and wear corrective lenses like glasses or contacts, you might notice "halo" effects or glare from lights or other bright objects. Glasses already have an option to reduce these sometimes bothersome effects with anti-reflective coating that helps with eye strain as well. Contacts haven't been as fortunate, until now. To put it in simple terms, "HD Optics" for contact lenses is essentially like the anti-reflective option for glasses. For people who don't wear glasses or contact lenses, trying to explain how light "looks" different with a pair of corrective lenses is actually pretty tough. That is probably why the term "HD Optics" was born, to simplify things.
One of the first contact lenses to go all out with an "HD" option is Bausch + Lomb's PureVision 2 monthly disposable lens. With this heir to the original PureVision line, Bausch + Lomb is starting to incorporate the latest technology to sharpen up images as much as possible. I pulled an image from the B+L website that does its best to simulate what it means in terms of "HD."
The face of Big Ben doesn't have any sort of funky lighting effect, which is supposed to emulate what the PureVision 2 HD will do for patients. If you want to read up more on the lens, you can check out the official webpage or talk to your optometrist.
So that is the fuss about "HD Optics." It is a way of telling people that contacts are making progress in reducing halo and glare and now, more than ever, there will be an option for everyone if they choose to wear contact lenses.
