Radiation from sunlight or use gadgets Too much can cause eye irritation. Therefore, it is important to use anti-radiation glasses to protect eye health, especially if you often do activities under the hot sun or use gadgets in a long time.
Eyes are organs that are very important for life. With a pair of eyes, one can see the world around them. If not cared for and maintained properly, the eyes can be damaged and cause vision problems. Therefore, we need to make sure our eyes stay healthy and protected.
Types of Radiation That Can Damage the Eyes
Radiation is a high-speed wave of energy or 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. 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 solar 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.
computer and gadgets
Blue light or blue lights that comes from a computer screen, laptop, or gadgets Others are thought to cause eye problems. Too long in front of the screen of these electronic devices can make you blink less often and cause dry eyes and eye fatigue.
Some studies also mention that blue light from gadgets Over time, it can cause damage to the cornea, lens, and retina of the eye. However, this still needs to be investigated further.
Nuclear radiation
Nuclear radiation is widely used in the medical world to treat and diagnose certain diseases. This nuclear radiation is used in X-rays and CT scans, as well as radiation therapy to treat cancer.
However, excessive or too frequent exposure to nuclear radiation can cause health hazards, such as cancer, developmental disorders in children, and damage to tissues and cells in the body, including skin and eye cells.
Tips for Choosing Anti-Radiation Glasses
Anti-radiation eyewear products on the market are usually only to block ultraviolet rays and radiation gadgets. While anti-nuclear radiation glasses and X-ray photos are not sold freely and are generally used by medical personnel who work near nuclear radiation emitting machines.
Anti-radiation glasses are specially designed, so they are different from ordinary eyeglass lenses. The following are some tips in choosing good anti-radiation glasses:
1. Able to block radiation
Plastic or glass lenses basically only block out a small amount of ultraviolet light, but adding a special coating to the lens is one way to completely block out ultraviolet light.
Therefore, when choosing sunglasses, you must make sure that they are equipped with a special coating that is able to ward off ultraviolet radiation. Prioritize coatings that can counteract radiation by 99-100 percent or labeled 400 nm.
2. Made with good lenses
Make sure that the anti-radiation eyeglass lenses are properly designed. It's easy to test. Put on the glasses and hold the glasses at the ideal distance from your view and look at a pattern of squares or straight lines while closing one eye.
Move the glass slowly from side to side, and up and down. If the lines still look straight, then your lenses are good eyeglass lenses.
3. Have polarized lenses
Glasses with polarized lenses (polarized lens) can help reduce glare from the sun reflecting off glass, mirrors, roads, or puddles. Therefore, for the sake of comfortable 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 making sure that the glasses you buy are able to ward off ultraviolet radiation, you also have to consider the frame and size of the glasses you choose. Glasses with larger frames and lenses are considered to be able to cover 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, it is also recommended that you wear anti-radiation glasses when you are outside during the day.
If you are still confused about choosing the type of anti-radiation glasses, you can consult an ophthalmologist. The doctor will suggest the choice of glasses according to your eye conditions and daily activities.
