If you already wear eyeglasses for near-sightedness, you may require to wear bifocals or to get a second pair of glasses for close work.

The Categories Of Sunglasses Ultra Violet Protection (UV)
The sunglass lens tint reduces visible light and provides effective protection against sun glare. Renowned manufacturers ranked lenses into different categories depending on light conditions. To find the category to which a pair of sunglasses belongs, you just look at the interior of the frame. Ranking ranges from 0 to 4 according to European standards:
Category 0: Passes 80% to 100% of brightness. Clear or slightly tinted, perfect for indoors and outdoors with cloudy weather.
Category 1: Passes 43% to 80% of brightness. Slightly tinted glasses: the perception of the luminosity is reduced. Good for cloudy days and in the city.
Category 2: Passes 18% to 43% of brightness. Moderately tinted lenses: light perception average. Particularly suitable for summer.
Category 3: Let go 8% to 18% brightness. Dark glasses: strong sunlight. Very suitable for southern climates, water reflections, beaches and mountains.
Category 4: Passes 3% to 18% light. Very dark glasses: exceptional solar luminosity (not recommended for driving). Ideal for high mountains and glaciers.
UV filtering occurs through appropriate lenses regardless of the level of "darkness" of the tint. It's not necessarily the darkest glasses that best protect the eyes, but sunglass lenses made with materials of high quality, high capacity UV-ray filters.
The sunglasses with the CE mark comply with all requirements and directives, and provide adequate ultraviolet ray protection for the eyes. The CE mark often etched to the inside of the frame and more specifically to one arm of the sunglass frame, shows compliance with safety requirements in accordance with EU directives. There is no independent body that inspects each model individually. However, the famous manufacturers of glasses are often voluntarily complying with these standards due to their desire to preserve their global standing and to keep their reputation intact. You can also check for yourself the validity of that mark by consulting an expert in the optical world or simply an optician.

Quick Short Facts About Bifocal Reading Glasses
Recently, more and more people at a young age suffer from impaired vision. As a result, the demand for bifocal reading glasses is high. Spectacles together with contact lenses are considered some of the most innovative products today. Their function is quite valuable as they are tools for helping people to see much clearly and conveniently. Compare to contact lenses, spectacles offer more convenience to people age 40 and up.
Origin of Bifocals
As their name implies, spectacles are eyeglasses with two distinct optical powers. They are designed for individuals with symptoms myopia or astigmatism. The eyeglasses were invented way back around 1760. They are first developed or used by Benjamin Franklin, an American statesman and investor. During this time, Benjamin suffered from presbyopia and nearsightedness. This inspired him to create his own eyeglasses.
The Benefits of Bifocals
Spectacles are designed to allow the user to improve his focus on a certain object either far or near him. Presbyopia is a condition where in a person suffers from the difficulty of focusing objects that are far and near. The spectacles provide an ease of transition from focusing onto far objects to near objects. They have two sections on each lens. The upper section is expected to aid in distance vision while the lower section magnifies objects. With this kind of lens, you do not need two sets of eyeglasses as the spectacles provide everything you need.
Styles and Designs
Spectacles can come in wide variety of styles and designs and they can be bought in high-end fashion stores, local eye care center and even online. These eyeglasses are available for both men and women. They can have classy feminine frames or thick metal frames. The styles vary from retro to modern style. One great example is the tinted reading glasses that are bifocal. Basically, they are sold in four distinctive designs depending on the method use for embedding the lenses.

How to Choose the Best Safety Glasses and Goggles
Check The Safety Standards
There are many safety glasses and goggles that are marketed as being protective that are not. How do you tell? Look for a code on the lens or the frame. This code means they have passed a safety test. Different codes represent different tests, so know what code you need to look for.
Check The Materials
Many safety glasses and goggles are made from recycled resins, which tend to distort and yellow over time, causing eye fatigue and strain. A better choice is virgin resin polycarbonate. It is more durable, so will last longer and not distort. Additionally, check that the lenses are at least shatter resistant, if not shatter proof.
Check The Fit
One size does not fit all, and many safety goggles come designed for people with larger features. Got a big head? A big nose? Big ears? Look for a model that is meant for you. Check if it has adjustable features to accommodate your face shape.
Don't Forget Comfort
You know style is out the window, but comfort should be a priority. Look for safety goggles with comfort features such as soft nose-pieces, flexible frames, lighter weight, and soft-covered arm tips.
Fill Your Prescription
If you wear eyeglasses, make sure your safety glasses or goggles will fit over them and not obscure or distort your vision. You can also find prescription protective eye wear, and leave your regular glasses at home.
Think Ahead
If you're wearing them on a regular basis, chances are that eventually you'll bust a lens. You can keep costs lower by choosing safety goggles that come with, or accommodate, replacement lenses, so you don't have to buy a whole new pair.
Look For Extras
How are you going to be using your eye wear? What other needs do you have? If you will be removing them often, look for safety goggles that come with a cord. If you need more protection, seek out eye wear that features brow guards, side shields, or wrap around lenses. Other valuable extras to look for are vented frames, padded lenses, anti-fog lenses, hard coated lenses, and UVA and UVB protection.
Safety glasses and goggles are an important tool, so be sure to choose carefully. It's always a good idea to err on the side of caution and get more, rather than less, protection. After all, you can buy a new pair of safety glasses...but you've only got one set of eyes. So take care of them, and protect them wisely.
