Safety glasses and work gloves are my families business.
Remember to look for the stamping of Z87.1 (The ANSI rating that is assigned to "safety glasses") on the temples. My famlies business sells regular safety glasses ranging from $.97 to over $100 for the "branded" glasses. A good pair of safety glasses really only costs $.97, but you will not look cool in them. The most popular sellers today are wrap around safety glasses. They come in many different lense colors, and coating options. In recent years polarized lenses have been approved and have become moderately popular. One of the most popular glasses that we sell is an indoor outdoor mirror. it is a mirrored coating on a clear lense which allows for great visibility indoors and protection from the sun outdoors. My recomendation is to forget about interchangable lenses, and buy some cheap safety glasses. That way you dont have to worry about trying to find replacment lenses, and if you loose them it is no big deal. $3-11 is the mid price range for a pair of safety glasses unless you are buying boxes at a time.

OTG (over the glasses) does not have much in terms of choice. Everybody knows the Uvex Astro spec and Ultra spec when they think of safety glasses ten years ago. If you want to go with goggles there are many new styles out that are reasonably priced and comfortable.

Prescription safety glasses are avaliable from many suppliers, all you need is a prescription and some $. They are not too expensive when you consider the cost of regular eye glasses.

On the topic of eye wash... READ THE BOTTLE they are water and saline solution. Depending on the activity several ounces are all you need to flush the object out. All eyewash is created equal!!!
