Can you wear blue light glasses while driving?

The damage of blue light has a cumulative effect. The longer the exposure time is, the more serious the damage of retinal cells will be, which will eventually lead to irreversible damage of the structure and function of the retina. Once the retina has permanent damage, degeneration will directly affect the metabolism and function of photoreceptor cells, resulting in vision loss. It depends on the glasses you're wearing. The function of anti-blue light glasses depends on the material of the glasses. Some blue light glasses have a special anti-reflective coating, which can reduce glare. These glasses are definitely helpful when driving at night.



What are the characteristics of a titanium frame?

The so-called pure titanium, titanium refers to the purity of more than 99% of the titanium metal materials. To tell if a pair of glasses frame is pure titanium, we look at its purity. Because of the high melting point of titanium, lightweight, strong corrosion-resistance, used for the frame, they can wear for a long time, and will not let the bridge of the nose have a sense of pressure. But its disadvantage is that the material is soft, and only the relatively rough frame lines are made to ensure the stability and strength of the frame. Titanium frame has the advantages of corrosion resistance, acid and alkali resistance, high stability, good elasticity, good toughness, not easy to deform and fade. General glasses frame contains copper, so when we wear for a long time .it will produce verdigris, namely, copper sulfate. It is a toxic substance and is harmful to the human body. Because pure titanium tends to be soft, copper has to be added to make the frames more stable, which is why the frames have to be replaced over time.


The correct method for lens cleaning

Wet it with water first, and then add a little detergent or hand sanitizer to each lens. Dip your fingers to the back of the lens, and then scrub with your fingers. Be careful not to use too much force to prevent the lens from being worn out by grit.

The key here is to rinse. First of all, never use hot water, because hot water will cause the lens to expand due to heat, which will crack the film in the resin lens.

Finally, you should rinse with cold water, do not wipe with a cloth, because any glasses cloth or suede can not perfectly wipe the lens, even the more you wipe it, the more indistinct it gets. If there is hard dust in the cloth, it will scratch the lens.



How do prism glasses work?

Prism glasses rearrange the images by bending the light and moving the images the eye sees to the desired position. They can align?with what each eye sees, eliminating the double image that the brain interprets. When the images seen by both of your eyes are rearranged, the light is redirected to the right position in the retina of each eye. The brain fuses these two images together to form one clear image.


The effects of night blindness on driving

As we age, our pupils will be narrow little by little, so they can't dilate as quickly. The smaller the pupil, the less light reaches the retina, making it harder and harder for the retina to see at night. This is called night blindness, and it's a condition that makes it difficult for your eyes to adjust from bright light to dim light. This makes driving at night especially stressful in your 50s, 60s, and beyond.



Different Types of Progressive Lenses

The short corridor progressive lenses that are designed to fit into small frames. They trade practically for a more fashionable look. Some people have difficulty transitioning to short corridor progressive because of the lens size and vision can feel more distorted sometimes because of this.

Transition progressive lenses are the last type. They are a brand of photochromic lenses. These lenses darken when exposed to UV light to provide shade for your eyes. They operate as a useful alternative to sunglasses.
