Why bother tinting? Why not simply go full Polarized? To me these were really good questions! After all why bother doing something halfway if you are not going to do it properly? Right? Wrong!
We will look at some tinted glasses that fit over glasses and how they will work for you. It will be seen that you may need to have different color tinted safety glasses that fit over prescription glasses dependent upon which kind of task you will be performing in any given lighting condition.
In the first case, no tint, clear lenses are good for general purpose normal to lower light levels. Clear lens or no tint lens safety glasses allow over ninety percent of available light to pass through to your eyes. The clear lenses will absorb almost one hundred percent (ninety-nine point ninety-nine) of harmful ultra violet light.
As the bulk of available light reaches your eyes you will see things in their true color. Thus, clear lenses are a good lens type for general purpose use.
In the second case these will be wonderful for reflections and outside glare. However, Polarized lenses will not work well for you inside, even if there is bright lighting most things will be too dark for you and really hinder you.
Recently I was on a drive that took me east. I had set out at night, ending up driving into the sunrise. Just before the sun had risen enough to blind me I wore my polarized safety glasses that fit over my glasses. The sun did not bother me one bit as it rose higher into the sky, high enough for me to eventually remove them.
The two extremes of the clear and the polarized lenses show there is a lot in between.
Let us take a brief look at some safety glasses tints that are best over glasses and the lighting conditions where they are most appropriate.
It should be remembered that all high grade safety glasses will block almost one hundred percent of harmful ultra violet light.
There is at least one word here that we need to examine before moving on to use it. When I read the word contrast I think of the TV and adjusting the contrast on the picture.
But, what is contrast? According to Dictionary.com one of the acceptable meanings of the word contrast is: to compare in order to show unlikeness or differences; differentiate.
So in terms of glasses, to be able to adjust the visible contrast or differences of something, you only need to have a tint that will do this for you.
The amber or yellow tints are great for low light work, enhancing contrast and depth which is good for work requiring attention to detail. In effect this type of tint serves to brighten your environment which is probably why this tint can be used for driving.
The gray tint is ideal for you if the work you do requires movement between an inside and a bright outside environment on a regular basis. The gray tint allows enough light through the lens to see in normal indoor lighting and provide good glare protection when having to move to that bright outside.
The blue lens is very similar in properties to the gray lens and has similar uses. Being able to move between indoor lighting to outdoor sunshine without hurting your eyes is key. The blue lens will provide more protection against the glare of artificial lights.
The copper or brown tints are great for wearing outside to reduce bright sunlight and glare that cause eye fatigue. As a bonus they also happen to increase the contrast of the things you look at.
The vermilion tint is great for indoor use as it increases contrast and could be use for such tasks as inspections.
A green tint sits between a brown tint and a gray tint. This tint will give more contrast than a gray tint and at the same time provide more brightness filtering than a brown tint. Green, being a neutral color will not adjust colors as seen by you.
So Many Tints!
While there is no one best tint to use for every lighting environment you could find yourself in, having two or three of what you consider to be the best for you is a wise thing to consider and even do.
Tinted safety glasses that fit over glasses are readily available in many different tints.
We have looked at a general overview of the kinds of tints available for safety glasses that fit over glasses. It can be easily seen that no one tint is best for all lighting situations. In view of this, more than one type of tint should be readily available to you if you move between markedly different lighting environments.
There will be a post that will detail out the kinds of tints best for different kinds of work and occupations.
For now this post has given you a good idea of the kind of tints available to you, including why you should consider them.
Aim for zero accidents and be safe!
