What is night blindness?

Diminished night vision can also be called night blindness. When you suffer from night blindness, it does not mean that you can't see anything at all at night. This means that you have difficulty driving or seeing things in dark or dim lighting conditions. Night blindness also makes it difficult for the eyes to change from bright light to dim light. This is why night driving in oncoming vehicles can be challenging for some people with night blindness.

Many people have experienced a condition called night blindness, which can make driving at night difficult. Driving glasses at night should help alleviate this situation. However, research shows that night driving glasses are generally ineffective.

If you encounter problems while driving at night, please make sure that all reflective surfaces in your car are clean and free of dirt. You should also see an ophthalmologist determine the cause of the problem. Many causes of night blindness can be easily corrected, making you and others safer during the journey.


Wear glasses normally after being fitted with glasses

If you have myopia and have been diagnosed as true myopia at the same time, and the degree is above 0 degrees, you should wear suitable myopia glasses for correction. Once equipped with glasses, you should wear them except for washing your face and sleeping, because myopia patients are in a state of emmetropia after wearing suitable glasses, and the natural relationship between adjustment and convergence is restored. Wearing glasses is not only to improve eyesight, but also to read and work within an appropriate distance, so that there is a normal coordination relationship between the adjustment of the eyes and the convergence function, and to avoid eye fatigue.



How do you identify the refractive index of lens?

In reality, this problem is often a problem for optical shop practitioners, sometimes they worry about whether the manufacturer's lenses match the nominal value of the refractive index. We need a prop, and that's the camber. Because it can be used to measure the strength of the lens. The luminosity of the lens can be calculated by subtracting the curvature of the inner and outer surfaces of the lens. The curvature difference of a lens of the same luminosity is inversely proportional to the refractive index, that is, a lens with a higher refractive index only needs a smaller curvature difference to achieve the same luminosity.


Semi-rimless glasse with lightweight structure

Semi-rimless glasses are not heavy and thus very comfortable to wear even over a long period of time. The frame is used with less material and can reduce the weight of the glasses themselves so that the glasses are lighter. And they can reduce the pressure on our bridge of the nose, for our bridge of the nose, they can reduce a lot of burdens. Because they weigh less, they have a smooth and foldable style.



TERAISE Polarized Clip-on Sunglasses Over Prescription Glasses

The use of a yellow night vision clip helps reduce the glare of other vehicles' lights effect, and a nearsighted night vision clip can improve the safety factor of night driving. You can wear myopic prescription night vision glasses for a small amount of money, saving at least $350 / euro. It only weighs 4 grams. With a strongly polarized lens, the glare can be weakened, simple, and beautiful. On cloudy, rainy, or foggy nights, it's safer to wear a night vision clip.

Crizal lenses have excellent anti-fouling, abrasion resistance, anti-glare functions, and good light transmittance. Airwear lenses are PC lenses, and their chemical name is polycarbonate, which is a thermoplastic material. PC lenses are extremely tough and will not break (2cm can be used for bullet-proof glass), so they are also called safety lenses, which are currently the lightest materials used for lenses.

You can choose driving goggles.

The goggles partly filter the far-light from the car. Products sold online include glasses with yellow lenses and yellow translucent shades that clip onto car shades. Shades block out oncoming far-light, while glasses prevent rearview mirror glare from vehicles behind. Most of the light emitted by car headlights is short-wavelength ultraviolet and blue light. The yellow polyester blocks them while allowing the longer wavelengths of red and green light to pass through, making the headlights softer when seen through the goggles without reducing the brightness of the road and the surrounding environment.
