Radiation from the sun or excessive use of gadgets can cause eye irritation. Therefore, it is important to use anti-radiation glasses to protect eye health, especially if you are often active in the sun or using a gadget for a long time.
The eye is a very important organ for life. With a pair of eyes, one can see the world around him. If not treated and maintained properly, the eyes can be damaged and cause vision problems. Therefore, we need to make sure the eyes stay healthy and protected.
Types of radiation that can damage the eyes
Radiation is a wave of energy or high-speed particles, which can occur naturally or artificially. The following are the types of radiation that are harmful to eye health:
Ultraviolet light
Ultraviolet radiation from the sun is one of the main causes of eye damage. Ultraviolet light is divided into three types, namely UVA, UVB, and UVC. The types of ultraviolet radiation that can cause negative effects on vision are UVA and UVB.
Eyes that are too often exposed to both types of sun radiation can experience various diseases, such as photokeratitis (inflammation of the cornea of the eye due to excessive sun exposure), pterygium, eye cancer, cataracts, and macular degeneration.
Computers and gadgets
Blue light or blue lights that come from computer screens, laptops, or other gadgets can allegedly cause interference with the eyes. Too long in front of the screen of these electronic devices can make you rarely blink and cause dry eyes and tired eyes.
Some studies also mention that the blue light from the gadget can eventually damage the cornea, lens, and retina of the eye. But this matter still needs further investigation.
Nuclear radiation
Nuclear radiation is widely used in the medical world to treat and diagnose certain diseases. Nuclear radiation is used in X-ray and CT-scanning, as well as radiation therapy to treat cancer.
However, excessive or too frequent exposure to nuclear radiation can cause health hazards, such as cancer, growth and development disorders in children, and damage to tissues and cells in the body, including skin cells and eyes.
Tips on Choosing Anti Radiation Glasses
Anti-radiation eyewear products on the market are usually only to ward off ultraviolet rays and gadget radiation. While anti-nuclear radiation glasses and X-rays are not sold freely and are generally used by medical workers who work near nuclear radiation transmitters.
Anti-radiation glasses are specially designed, so they are different from ordinary eyeglass lenses. The following are some tips for choosing good anti-radiation glasses:
1. Able to dispel radiation
Plastic or glass lenses basically can only dispel a small amount of ultraviolet light, but the addition of a special coating to the lens is one way to completely dispel ultraviolet light.
Therefore, when choosing sunglasses, you must ensure that they are equipped with a special coating that is able to ward off ultraviolet radiation. Prioritize coatings that are able to ward off radiation by 99-100 percent or labeled 400 nm.
2. Made with a good lens
Make sure that the anti-radiation eyeglasses lens has been designed correctly. The way to test it is easy. Wear glasses and hold the glass at an ideal distance from your sight and see a square or straight line pattern while closing one eye.
Move the glass slowly from one side to the other, and to the top and bottom. If the line still looks straight, then your lens is a good lens.
3. Has a polarized lens
Sunglasses with polarized lenses (polarized lenses) can help reduce the glare of sunlight reflected from glass, mirrors, roads, or standing water. Therefore, for the convenience of activities during the day, it is recommended to use anti-radiation glasses with polarized lenses.
4. Has a large frame and lens
In addition to ensuring that the glasses purchased are able to counteract ultraviolet radiation, you should also consider the frame and size of the glasses you choose. Glasses with a larger frame and lens are considered capable of covering the area around the eyes well.
Protecting the eyes from excessive radiation exposure is one way to maintain eye health. In addition to limiting the use of gadgets and resting your eyes from time to time while working in front of a computer screen, you are also encouraged to use anti-radiation glasses when you are outdoors during the day.
If you are still confused in determining the choice of types of anti-radiation glasses, you can consult an eye doctor. Your doctor will suggest the choice of glasses that suit your eye condition and your daily activities.
