Safety glasses don’t have to look clunky anymore
Over the years those awkward, geeky safety glasses people put on for eye protection on the job site have been made safer, more comfortable, lighter, and better looking. The resistance to hard impact has increased significantly with the development of durable new materials which can accommodate prescription lenses or be worn over contact lenses without causing any optical distortion. Newer safety lenses are fabricated from polycarbonate, a material that has superior resistance to UVA radiation, and was first developed for airliner windows and face shields for astronaut helmets. Lenses on older safety glasses were made out of Crown glass or Columbia resin plastics, and did not have the impact resistance of polycarbonate, nor could they be adjusted by applying heat as polycarbonates can be. The effect of hard impacts on polycarbonate safety glasses is not like the impact effects on hard substances like plastic or glass, which can readily crack or break, but rather more like impact-resistant bulletproof glass instead. For people who require prescription lenses, the same kinds that you find in regular glasses are available in safety lenses, including single vision, bifocal, trifocal, occupational, and progressive lenses. There are modern models of safety glasses that look good enough to wear away from the job site, such as the more costly ones with Titanium frames, or the inexpensive ones with frames made out of resin plastic. There are safety glasses made for athletes which can also be utilized as job site glasses, but not all job site glasses are appropriate for use by athletes.

Digital scales vs. mechanical scales
Digital scales perform a wide variety of functions and come in lots of different sizes and styles, but basically the only kinds of scales are either high quality scales, or inexpensive good-for-nothing scales. Digital scales are the most exact you can purchase, and you will find one for particular needs such as bathroom scales, shipping scale, or food scales. While scales have an obvious practical function, they are also symbols of justice and fairness, as embodied in the famous “blind justice holding the scale” symbol. While it is difficult to imagine Lady Justice holding a digital scale, the fact is that conventional scales have been generally supplanted by the on-going digital revolution. Conventional mechanical face scales have never been precisely accurate, whether they are utilized in the kitchen or the bathroom, but a high quality digital scale always gives you the exact weight. The read-out from a digital scale provides instantaneous accuracy, and offers far better performance than the fluttering dial of the traditional mechanical scale. You need to be cautious when you buy a digital scale, as there are untrustworthy scale merchants dealing knock-offs of major brands on the Internet. Don’t squander your money on second-rate scales no matter how pleasing the price may be, as these cheap scales will not perform well.

Drill bits are available in many different types and sizes
Anyone who uses a power drill knows that you will want a full selection of drill bits to deal with all the jobs you have around the home. Different types of materials will require different types of bits to produce a good outcome. Twist bits are commonly used to handle wood, plastic and metal and are available a broad range of sizes for various applications. Masonry bits are ordinarily made from tungsten carbide with steel, and are perfect when you need to drill holes in stone, concrete, tiles or brick. If you want to make a very clean hole your best bet will most likely be a bullet pilot point which uses a center point and spurs to create an accurate cut. If you are drilling holes at the edges of your material or holes that overlap you might want to turn to a Forstner bit. If you are drilling a bigger flat-bottomed hole you will want a flat wood bit which can vary in size anywhere from 8 to 32 mm.
