When do night driving and car lights bother you?

The issue: Many drivers complain that night driving makes them too tired, focusing on the fact that oncoming car headlights blur their vision and strain their eyes. But is the bright light at night the ultimate culprit?

The causes:
-It is known that, in sunlight or sufficient artificial lighting at night, all the photoreceptors in the retina of our eyes are activated, and therefore we have better vision. On the contrary, in a dark environment, fewer photoreceptors are activated, and when the intense light radiation from, for example, car headlights is added to this , annoying glare is caused.

-But the main cause of blurry and tiring night vision is that many of us do not wear the appropriate correction in our eyes. Even a slight myopia or hyperopia or change in our degrees, makes us see the objects around us larger and dimmer. And these small degrees during the day may not be particularly bothersome, but in combination with poor lighting or even bright lights at night, they result in absolute discomfort in our eyes.

The most susceptible group of people:
We are all candidates for the above discomfort, but it is easier for people who have never worn glasses to acquire it. Reaching the age of 40 and above, presbyopia appears, which although concerns blurred near vision, it is statistically clear that from the age of 45 and above, in many people it "unlocks" a slight hyperopia for distance, which we wrongly neglect.

The solutions:
The first step is to determine, through an optometry test, if there is any minor refractive problem (degrees) for distance.
2nd step , is to make glasses for distance, which contain (if any) our distance degrees, combining them with the appropriate coating of ophthalmic lenses, which filters the high energy (400-420nm) coming from the lights. The combination of the two above solutions, will rest our eyes, and we will see correctly, regardless of the lighting conditions.

Cost of lenses that filter high energy (400-420nm) ≈100€

*Yellow lenses on the market do not help with our night driving, as they may cut off the bright light due to their color, but at the same time they cut off part of the visible spectrum, and self-neutralize the effect. Besides, as already mentioned above, the main cause of blurred and tiring night vision is that many of us do not wear the appropriate distance correction in our eyes.
