Eye problems that may occur while driving.

Visual fatigue and xerophthalmia: when driving, the spirit and eyes are in a highly tense state, reducing the blink of an eye, which will easily cause eye fatigue and xerophthalmia. Flash glare -- car headlights and city light pollution -- can cause serious damage to the eyes. UV damage: UV radiation is strong when driving in the daytime, especially in the plateau and snow weather. Nocturnal myopia: nocturnal light is insufficient, so it can make the eye pupil dilate, causing nocturnal vision to drop influence driving safety.


Prepare a few pairs of glasses

Many people now have a 'reserve' of glasses. For example, you can choose two pairs of glasses. One pair is for daily use, and the style should be relatively simple and traditional. The other pair is for use at gatherings or weekends and can be as cool as you want. The more conservative style is a thin and bright metal frame that matches the shape of your face. For the other pair, you can choose a flat plastic frame or a shiny polished metal frame with a unique shape.



Why Are My Progressive Lenses Blurry?

Can You Put New Lenses in Old Frames?

In this section, we will show you how to replace new lenses with old frames. In general, optical shops will replace the lenses for you if your frames are in good condition and the shapes of the lenses is not too complicated.

So, can you put new lenses in old frames? Of course, you can do that if your old frame is good and shape of lenses is not too complicated.

However, glasses lens replacement depends on the quality of your existing frames, their conditions, and your prescription specifics. Not every pair of sunglasses or glasses for that matter can be reglazed. Sometimes fresh frames are required to match your new lenses. By far the most common reason for this would be because the existing frame is becoming brittle or is otherwise at risk of breaking. There is no point putting beautiful new lenses into a frame that breaks either during fitting or soon after.

In addition, when considering glasses lens replacement, you need to consider the materials of frames. In general, plastic frames are more likely to become brittle with age than metal frames. Of course, there are some other factors to be considered.

In addition to the well-known rent, they have the costs of labor, decoration, and so on. There is another important reason. It is the inventory loss because of the style problems. This aspect of the cost must be amortized. From the structure and appearance design of the glasses frame, the development and application of raw materials, processing technology, to manufacturing equipment and procedures, the actual cost may be much higher.
