What Are HD Sunglasses?
The HD sunglasses are a new type of sunglasses that claim to give the person wearing them "high definition clarity". The sunglasses are supposed to enhance brightness of light and color, as well as reduce the glare to almost nothing at all. You can buy HD Sunglasses for a low price usually between $10-$20 and come in attractive styles and frames. Even though they are designed to make things more vivid and bright, they also feature UV protection from the sun.
How Do HD Sunglasses Work?
HD sunglasses are not exactly "high definition" in the sense that there is some kind of computerized technology embedded in the lenses, but rather the lenses themselves are a variation of amber-tinted lenses that are designed to filter out blue spectrums of light, thus enhancing the vividness of colors. Though they do give the impression of high definition clarity, they don't actually possess your traditional HD technology used in TVs and such. At least you won't have to worry about your lenses short circuiting in the rain.
Do The HD Sunglasses Actually Work?
The answer to this question simply depends on how you define "work". If you ask 80% of the people who try them on, they will tell you that they do in fact make everything brighter and more colorful with less glare, most agree that using the term "high definition" is somewhat misleading and unwarranted. It is likely that the manufacturers of the HD sunglasses chose to use "HD" as part of a gimmick to attract more customers.
Scientifically speaking, the HD sunglasses are not technically "high definition". However, that is not to say that the HD sunglasses aren't unique or make things look more vivid than usual. Most customers are satisfied with the results and low price, although perhaps a bit confused about the slightly misleading "HD" prefix used to sell them. For a $10-$20 pair of good-looking sunglasses that reduce glare and make colors a litle more vivid, they are a pretty good deal in that you don't have much to lose. Many sunglasses sell for hundreds of dollars and don't offer near as many unique features as the HD sunglasses.
The HD sunglasses are cheap, stylish, ad produce many unique and predominantly satisfying results. The "high-definition" gimmick may be a little over exaggerated, but hey - that's marketing for you. At $20 a pop they present a good deal for curious buyers to make the final plunge into purchasing them. Since the majority of people are satisfied with the results, you could always save your HD sunglasses and use them as a gift for a friend or family member if you don't like them.
