It is much more fun to play with a microscope in which we can observe samples such as the cells of an onion or microorganisms in a pond with clarity and sharpness.
Ease of use
Children's microscopes should be easy to use . It is important that they can be used intuitively and that they do not require following complicated instructions. Its ease of use must be in accordance with the age of the child . For the little ones it is more suitable to buy a simple microscope that does not require complex steps for its operation. The best option would be to buy a microscope with three fixed objectives and with some samples prepared to observe.
Accessories are essential to make microscope operation more fun. In the most basic cases the accessories can simply be a series of samples prepared to observe (cotton cells, onion cells, insects, etc.). The most advanced accessories are slides and coverslips for children to prepare the samples they want to observe themselves. Most microscopy kits often also include a pipette and sample dyes .
Children's microscopes should be robust and not include parts that can be easily broken. Children's microscopes are generally already designed to comply with all applicable safety regulations. Still, it is important to take this factor into consideration and make sure that the child who is going to play with it is the recommended minimum age according to the case.
The price is one of the factors that can limit our choice. The cheapest microscopes are usually made of plastic and include few accessories. Low prices can be attractive and perhaps they are the right choice in some cases.
Here are some tips to keep in mind to make a good choice:
On the beach, in the mountains or just in the city, wearing sunglasses is recommended to protect yourself from the dangers of the sun's rays. This is also true for drivers, who should take advantage of the prospect of vacations to have their eyes checked and choose the most appropriate pair of glasses.
Sunglasses: to preserve a capital that is running out
Just like the sun capital our skin has, our eyes wear out with age, which is accentuated by the rays of the sun.
Did you know that our glare resistance decreases with age by about 50% every 12 years?
That you have to protect your eyes from the sun from childhood?
And that the maximum natural protection is reached only at the age of 15?
For all these reasons, you should wear sunglasses in sunny weather, at any age and regardless of activity.
But not just any glasses ...
The filtration of the glasses must be adapted to the intensity of the radiation, the covering frame and the model certified in conformity with the European regulation in force. Beware of glasses that are more of a gadget because behind any tinted plastic, the pupil dilates and lets the rays to the retina. If the plastic does not filter the rays, the retina is exposed to the damaging effects of the sun. So it's even worse than not wearing glasses at all!
Driving too, sunglasses are essential
Driving too, it is essential to wear the best sunglasses for driving to protect his eyes of course, but also to prevent accidents. Under certain conditions, the luminosity and the rays of the sun are real risk factors: dazzling, reflections, entries and exits of the tunnels, sun shaving at the rising and the setting of the sun, etc.
You must also make sure you are not carrying a vision problem. According to the National Association for the Improvement of Vision (Asnav), one-third of drivers have one or more eye disorders. But 90% of the decisions and gestures necessary to the driving depend directly on the sight. It is therefore necessary to regularly check his eyesight and if necessary correct it (myopia, astigmatism, alteration of the visual field ??).
This approach could be part of the preparations for your holiday, as well as the purchase of a good pair of sunglasses ?? !
