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.


For collection

Glasses' material and styles are constantly updated. It is more and more light and more beautiful. Early glasses may have become antiques. You might as well collect your retired glasses according to the time and story, and attach the tragic history of the glasses. Perhaps many years later today will become a beautiful memory. You might as well try the nostalgic and literary style.



What Is Anti Reflective Coating?

Anti reflective coating, also known as AR, anti-glare, no-glare, or glare-free coating, can provide benefits to your vision. Anti reflective coating is added to lenses to reduce glare caused by light hitting the back of the lenses to improve your vision and make your eyeglasses more visually attractive.

Anti reflective coating will eliminate all reflections from the front and back surfaces of your lenses. Hence, more light is able to pass through your lenses which improves your vision. At the same time, fewer distractions are visible and the lenses are hardly noticeable, especially in the dark. So, is anti glare worth it? Most people agree that.


Progressive lenses and single vision lenses

Single vision lenses are the most commonly used prescription lenses. This lens type has a single field of view or a prescription ability of the entire lens and can be used to correct myopia (nearsightedness) or hyperopia (supervision).

Progressive multifocal lenses are lenses with different upper and lower powers for the upper part to see far, and the lower part to see near. The distance from the fixed power above the lens to the fixed power below the lens does not change suddenly, but there is a gradual transition between the two through the gradual change in refractive power.



Choose frames according to the face shape

For example, children with round faces should not choose too round frames, while children with long faces should not choose too long frames (the two rules apply to wearers of all ages). Choose the shape of the frame to beautify the face shape. It can be the primary judgment criteria.


They can reduce glare.

They can absorb blue atmospheric scattering and provides more contrast. When performance is your top priority, the right lens tone can give you the results you want. UV rays are blocked by a special coating on the lenses. And inferior sunglasses not only cannot hold back ultraviolet rays but let lens permeable luminosity drops seriously, making pupil greens. Ultraviolet rays can shoot in large quantities instead, your eye is damaged.



What are bendable glasses called?

Bendable frames, or memory metal frames, are metal frames that can be twisted, bent, and shattered without breaking or losing their original shape. It's made of a kind of smart metal that has a memory. Its microstructure has two relatively stable states. At high temperatures, the alloy can be changed into any shape you want. Memory metals are mainly nickel-titanium alloy and other materials. The structure of these alloys varies with temperature in the solid-state, the shapes of these alloys can be changed as needed, and will automatically return to their original shape at a given temperature. One unique aspect is its ability to return to its original shape, although the frame has been twisted, bent, or crushed. They are lighter and more durable than traditional metal frames. The bendable frames are made of composite metal alloys for bending properties. These lenses can be twisted and bent, and when they are released, they return to their original shape.
