Do cheaply made sunglasses offer the same amount of protection as better quality ones?
Thepinkpig
Not all sunglasses are created equal, just as not all cameras, microwaves, cars, etc. are as good as others. Although most sunglasses now offer UV ray protection, there are different classifications of UV proection, just as in suntan lotions. Many of the cheap sunglasses offer the least protection, and use a spray-on film on the surface of the lens to achieve this. This allow the protection to scratch or wear off. Quality sunglasses have this technology integrated into the lens itself. Additionally, most cheap sunglasses to not offer polarization, a feature which allow much of the sun's glare to be filtered out. The cheap ones that do claim this also use a surface layer for the polarization.

What color sunglass lenses blocks the most light?
the color of the lenses doesn't matter. It's the amount of protection on them. Often there is a sticker on the lens when you first buy the sunglasses that will tell you the amount of protection they offer. The higher percentage, the better!
What is the difference between the replica sunglasses and authentic sunglasses?
Replica sunglasses are usually cheaper "copies" of authentic branded sunglasses such as Gucci, Diesel or Prada etc. Replica sunglasses can vary in quality. If you purchase a pair of replicas from a market stall or from a "$2" shop, the chances of your sunglasses meeting the UV protection safety standards are very slim. In Australia, there are currently 5 categories based on the amount of light that the lenses absorb with 0 (zero) providing minimal protection from UV radiation and sun glare and 4 providing a high level of protection. The most common authentic/designer sunglasses available will have either a category 2 or 3 lens. A category 4 lens may be too dark to use for driving and may come with a warning. All designer sunglasses are required to supply information for their lenses so that the consumer knows how much protection they'll be getting. Because of these regulations, it is safer for the consumer to purchase their sunglasses from a reputable company rather than from a market or a "$2" shop where the products aren't properly regulated.
