Possible effects of driver's lens color on driving

Color plays a very important role in your everyday driving experience -- red, yellow, and green traffic lights, among many other signs and signals, are designed to grab your attention and keep you safe. If everything you see is yellow, you may make the wrong decision at the red light and may cause an accident. To keep your vision clear in night and day conditions, anti-glare night driving glasses are not just for night driving.



Bertoni polarized glasses

Bertoni polarized night vision driving glasses are made of strong, flexible, durable, and ultralight polycarbonate. Yellow polarization increases contrast, improves visual acuity, and filters out blue light. They are great for drivers, cyclists, and winter sports enthusiasts. The driving glasses with polarized yellow lenses block glare from headlights, reduce night driving glare, improve night vision, and improve color clarity and visual clarity. They are ideal for driving in low-light conditions. Most sports sunglasses glasses frames and goggles are made of polycarbonate because of their strong, thermoplastic, lightweight, and impact resistance features.


TR90 glasses frame

TR90 is not easy to deform and break, and it can withstand high temperatures and strong impacts. In addition, its material is relatively light, so many young people also like such glasses frames.



Plano Lenses vs Demo Lenses

When talking about the plano lenses, demo lenses will be talked about, too. Plano lenses are different from demo lenses. Demo lenses are nothing but lenses that are fitted into the demo frames at the optical showroom and workshops. The only purpose of demo lenses is to give a realistic aesthetic of the frame to the users so that they can get an idea of how it would look with corrective lenses. However, there is also no corrective power on demo lenses.

Compared with demo lenses, plano lenses provide good quality lenses that give your protection against harmful UV rays and blue light emitted from digital screens like laptops and desktops. In addition, you can also add an anti-glare coating to the plano glasses.


The life of the color-changing lens

There is a reaction fatigue problem in both compound reaction and bond-breaking ring-opening reactions. Therefore, there is a shackle in the process of discoloration, which is the life of the discoloration lens. Generally speaking, high-quality color-changing lenses can maintain more than 90% color-changing effect after 2 years of use.

What is the cheapest way to buy prescription glasses?

Optometry must be accurate. Optometry is the main basis for glasses. The accuracy of optometry is directly related to the success rate of the glasses prepared. Optometry must be accurate first, and the difference between the upper and lower levels should not exceed 12.5 degrees of the prescription. Secondly, the astigmatism axis should be accurate, and the general axis difference should be limited to plus or minus l to 3 degrees. In addition, the interpupillary distance must be accurate, and the interpupillary distance must be equal to the optical center distance of the lens. If you do not pay attention to the above-mentioned checkpoints in optometry, the prepared spectacle lenses will have blurred vision, prolonged visual fatigue, dizziness, nausea, and even diplopia. Optometry is best to go to a professional eye hospital. For children’s optometry or to wear glasses for the first time, you must use mydriatic optometry to be accurate. You can also check if there is any problem with the fundus, and go to the hospital to get more accurate optometry.
