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.


The arm length is an important part of the size of the glasses.

Spectacle frames are standard optical products. Just like people's clothes and shoes, they all have their own size. Usually, specs for the size of the glasses are on the inside of the temple, on the bridge of the nose, or on the label. In general, the frames of the glasses are marked with the width of the frames, the width of the bridge of the nose, and the length of the arm. For example, the inner side of the temple is labeled: 52口 18-135, indicating the lens width of 52mm, the width of the nose bridge of 18mm, and the arm length is 135mm.



Clear non-prescription sunglasses are a trend.

Clear glasses will not appear old, as long as the choice of their own frame is good-looking, although it is often said that a round face is suitable for angular frames, and a three-dimensional face is more suitable for rounded frames, but the collocation of face shape and frame can not be generalized. A transparent picture frame gives a person a feeling of intellectual, restoring ancient ways of literature and art model. There are a lot of people who use it to reflect their modeling. It seems that there is a pure sense of feeling. And people who use it do not lose the taste of literature and art, and there is a unique personality. Half of the transparent glasses are made of TR material and plate, which is light and comfortable to wear and have many styles.


How to maintain a hard-coated lens?

The hard-coated resin lenses can be identified by the sound of the tabletop tapping and the color brightness of the lenses. The lenses, which sound clear and have bright edges, are hardened. In daily use, avoid overheating environment. Avoid contacting with alkaline liquid, so as not to cause damage to the lens. And this damage is usually not formed in an instant.

Long-term use, sun exposure, and so on may make the coating slowly fall off. If the production of hard film technology is worse, the film is easier to fall off. When cleaning and adding a hard-coated lens, clean the particles on the front and rear surfaces of the lens with clean water first, and then blot dry with a clean soft cloth. Do not wipe the surface when the lens is dry.



Transition Lenses Problems

It is not convenient to rely on photochromic lenses when driving. It also may be unsafe if the driver depends on the prescription to see or is legally bound to wear prescription lenses when driving.

Besides, transition lenses are typically the size and shape of regular vision-correction lenses, which allows them to accurately correct the field of vision, but does not account for peripheral areas on either side of the visible range. Sunglasses operate by maintaining very dark glasses that expand over the field of vision and the peripheral with large, oblong lenses that block sunlight from both the front and sides. However, transition lenses are not typically dark enough for heavy sun and cannot block light penetration on the peripheral, leading to people having to resort to sunglasses again.
