Today’s EIO post is on magnifiers.

 

Benefits of Magnifiers

Magnifiers are great because they help to enhance vision. They enable people to undertake detailed work or compensate for a sight disability that lowers an individual’s vision. Magnifiers are valuable when one most focus on fine detail. In hobbies such as model-making, stamp collecting and cross-stitch, an individual will often use a magnifier so they can see intricate detail.

Magnifiers have specially designed lenses that bend light. This increases the size of text or a smaller object, making it better to see. To get the best focus on the task in hand, hold the magnifier close to the your eye. Then bring the work up towards it till optimal focus is achieved.

When carrying out intricate tasks with a magnifier, one should work in the natural light as much as possible to avoid straining the eyes. Where it is not possible to work with natural light, or where natural light isn’t adequate, utilize an adjustable light fixture. This allows light to shine directly on to the area being magnified.

Different magnifiers should be used for different tasks. Larger lenses tend to be less powerful than smallish lenses. Large lenses are useful when an individual wants all-round, low-level magnification. Large lenses work effectively for tasks like reading or completing a crossword. Where precision work is needed, a small powerful lens may very well be more appropriate. A good example of a smaller, powerful magnifier would be jeweler’s magnifier.

Handheld magnifiers are easy to use and cheap to buy. Some handheld magnifiers have built-in illumination, making it easier to see when the lighting is poor. These magnifiers are well suited for reading small print while active because they are light to transport. The disadvantage of some handheld magnifiers is that they leave the individual with merely one hand available to carry out tasks. This is fine if the individual is only holding a book, newspaper, and also magazine, but this may be restrictive.

Hands-free magnifiers are probably a better option for anyone with a hobby that demands the use of their hands, such like sewing, knitting, or model-making. Hands-free magnifiers hang around the individual’s neck. This is great for other assignments too, as they have large lenses. This version of hands-free magnifier offers small magnification, usually only doubling the size of any object.
