You can improve both the day and night vision by maintaining the good health practices and doing some eye exercises regularly.
Tricks to improve Night Vision
There are many reasons for the night blindness from the poor condition of the cataract to the trauma or other illness. If you do some tricks in the early stage, then you can avoid such problems easily. But in the severe condition or failure of the working stage, it’s mandatory you include more natural supplements and nutrients rich food in your diet.
1) Wear Red-Tinted Glasses
The eyes contain rod cells which help to see the object in the less intense light and so wearing red glasses or goggles for few minutes allows the rods to adjust your eyes and therefore you can even see in the darkest area.
This type of glasses blocks everything except red color and trains your eye to focus objects in the dim light. If you buy some products like the dashboard, try to get it in red than other colors such as white, blue or green to make the object appear sharper.
2) Avoid Looking Directly at Any Light Source
The pupil of the eye contracts and expands based on the amount of light that falls on it. If you see the light source directly, then it will become small and produces the clear image. The dim light increases the time to adjust the eye to see the object. The change in the light flow rate tends to extend the size of the pupil and in such problems, just close one eye while looking the light source.
3) Let Your Eyes Adjust to the Darkness Naturally
This is the best method to see the object in the dark place by slowly allowing your eyes to see in the low light. You can do this easily by sitting in the darkest place for some minutes before going out during the night time.
If you couldn’t find any dark area in your home, then wear a sleeping mask or place a small piece of cloth over the eyes. Another simple method is that squeezing and closing the eye tightly for few seconds.
4) Keep Your Eyes Moving
When you go to the low light place don’t stare at a single object because it will take more time to adapt and try to focus all the objects around you by moving the eyes. Whatever the light source may be, just keep blinking until you can see the things clearly and don’t focus on the particular area.
5) A Gentle Eye Massage
Close your eyes and apply pressure slightly over the eyes using the palms while you move to the dark room. After 10 seconds, your vision will turn to white and black, now open your eyes and you can check out the object in that place.
Natural Supplements for Night Vision
Use the tricks in the emergency situations, if you take the required supplements regularly, then it will improve eye power and reduces the chances of night blindness.
1) Vitamin A
The vitamins are important for the generation of essential components for absorbing the light in the retina. The vitamin A helps in the secretion of rhodopsin which improves the functioning of the cornea and conjunctival membranes.
The main cause of the poor vision or night blindness is due to the lack of vitamin A. So it is important to include vitamin rich foods in your diets such as fish, fortified cereals, and dairy products.
2) Fish and Shellfish
The omega-3 fatty acid helps to keeps the inner eye healthy by generating the photoreceptor in the retina and provides good vision. The cold water fish like herring, sardines, and salmon contains more DHA which is important for boosting the eye power. The shellfish and oyster are rich in zinc and retinol.
3) Fresh Vegetables
If you want to improve your health, then you have to include more colorful fruits and vegetables in your diet because they help to reduce the free radicals present in your body. Take green vegetables like broccoli, collard greens, kale, and spinach in your diet regularly for protecting your eyes from any damage. If you don’t want to eat the fresh vegetables, then make it as a smoothie and drink it to get all the nutrients.
A daily routine of healthy diet and some eye exercise definitely makes a drastic improvement in the poor night vision.
It is in your hands to take required steps to prevent the eyesight problems, try to follow the above tricks and take the necessary supplements.
The human eye plays the vital role in seeing the things happening around you, also helps to identify any object in front of you in midst of the size, color, and shape. Sometimes, just the natural eye power is not enough to see the clear image. There is much development of the night vision technology that helps in providing the ability to see even in the darkest place.
Night Vision Technology
This technology is initially used in the military and police force to identify the potential suspects and there is a number of commercial night vision devices available in the market. Many people are using this type of devices for hunting and finding objects during the night time. In this article, you can get more interesting facts about the night vision technology.
1) Different Types
There are different types of night vision devices available with interesting features at present, but the first most popular device is the image intensification which produces clear images using the available light in the surrounding.
The thermal imaging technology was developed and it creates pictures based upon the temperature of the objects. The latest one is the active illumination which includes both active source of illumination and the image intensification technology.
It is classified into five generations from 0 to 3. In the year 1930, the night vision devices are first introduced in the battlefield by the German army which is known as GEN 0. Then the version GEN 1 was introduced and it uses only the ambient light than infrared. Generation 3 was developed with the new technology and the best feature was the one that produces light amplification greater than the previous versions.
3) Image Qualities
The good night vision device produces a clear image and it mainly depends upon the resolution of the particular unit. If you want to get the high quality image, then choose the device with the resolution power 640 X 480 and some units come with the video facilities. It is important to check the image intensifier tube and the optical characteristics before buying the image intensifier devices.
4) How Does Image Intensifier Night Vision Work?
First, it receives photons from the natural light source such as stars and moon, and then the light flow falls over the photocathode plate which is fixed inside the tube. The light then transmitted through the vacuum tube strikes a microchannel plate for illuminating the picture. The best night vision device produces the high resolution 45 lp/mm (line pairs per millimeter).
5 How Does Thermal Night Vision Work?
It uses the sensor known as microbalometer for finding the temperature of the objects, the difference between them is calculated. From the collected thermal information, it develops the patterns of the objects to create the image.
6) Are There Cheaper Alternatives
The effective alternative for the image intensifier night vision is the digital camera sensors. The complementary metal-oxide-semiconductor (CMOS) and the charge-coupled device (CCD) are available in affordable price and using this, you can see what is going on in the dark place.
7) Why Does Everything Look Green through Night Vision Device?
When the electron hits on the screen coated with phosphor it converts them into photons for producing the image in the green color. It can also produce a black and white image but most people prefer green and black images because their assumption is that it will produce bright image than other combination of colors in the dark.
8) Thermal Imagers
If you want to find the animals in the woods during the night time, then it is necessary to have thermal imagers as they help to identify the heat signature of the particular object. But it will not provide the complete details about the animals, try to get a night vision device with the thermal imager to get the clear image you want.
Future of Night Vision Technology
The new technology which is going to be popular in the night vision is the shortwave infrared (SWIR). Using this type of devices, you can see the image that is normally invisible. Moreover, it will produce a picture in high resolution even in the darkest place using the infrared system.
Hope you got a clear idea about the night vision technology after reading the above article.
If you are planning to go for hunting, then never skip taking a night vision device so that you can identify the animals in the dim light easily.
