They promote rimless glasses to the boundary without limits, with no frames, hinges, and screws.

Transition Lenses Problems

Here, we will show you some common transition lenses problems.

Transition lenses are typically embedded with photo-sensitive chemicals or coated with similar films that produce the shading effect when exposed to light. This process makes the lens more expensive to manufacture and focuses on prescription glasses, thus raising the transition glasses cost. The transition lenses cost may be twice of the regular glasses lenses.

When you are driving with the transition glasses, they will fail to work. Car windshields typically come standard with anti-glare effects or films and laminates that break up some of the direct sunlight that enters the vehicle. This will reduce the transition lens effects, causing them to register a non-lit condition when the direct sunlight can actually be very bright.



Is there any relation between lens refractive index and lens definition?

First of all, in reality, from the point of view of the immediate situation, there seems to be no correlation. The refractive index is mainly related to the speed of light transmission into the lens. High refractive index lenses can be made thinner, lighter, and the technology required to do this is more sophisticated, so high refractive index lenses are more expensive. But does a high refractive index make the lens clearer? The higher the refractive index of the lens, the lower the Abbe number. The Abbe number is a very important parameter we use to measure the sharpness of the lens, which means that if the refractive index of the lens is high, that is to say, the sharpness of the lens is lower. If you have higher degrees, you can prioritize thinness and choose a lens with a higher refractive index, but don't overdo it.


Semi-rimless glasse look more stylish.

Semi-rimless glasses are very stylish and more creative than rimmed glasses. Women looking for the perfect glasses will look more elegant and stylish in these glasses.

Do all glasses come with nose pads?

The glasses without the nose brace are plate glasses. In reality, there is still a nose pad, but it is relatively small and it's part of the frame. The westerners have high nose bridges, and many glasses have no or very small nose pads. For example, Harry Potter's glasses have no nose pads. European and American brands will change their nose pads for the Asian market. Eyeglasses without a nose pad rely on the bridge of the nose to support the center beam. It's hard for Asians to stand up, and their eyes are more protruding than sunken like westerners. Glasses are usually demanded to keep a 12mm distance between the lens and the eyeball, otherwise, the optical performance will have a great impact.
