When it comes to ordering your next pair of glasses—whether they’re from David Kind or any other brand—the most important thing to ensure is that your eyeglass prescription is up to date. Understanding your prescription can give you a better sense of how your eyes are changing over time. At first glance, your prescription from the optometrist may seem confusing, but learning to navigate it can be incredibly helpful! Here’s a guide to help you understand your prescription and what to focus on.
### Nearsightedness (Myopia)
Nearsightedness means that you can see objects clearly when they're close but struggle with distant ones. If you’re nearsighted, your prescription will show a number with a minus sign in the **sphere** column. This number represents the lens power needed to correct your vision, measured in diopters.
### Farsightedness (Hyperopia)
Farsightedness, or hyperopia, makes it hard to focus on nearby objects, while distant ones appear clearer. For someone who is farsighted, their prescription will include a number with a plus sign in the **sphere** column.
### Astigmatism
Astigmatism occurs when the front surface of your eye has an irregular curvature, leading to distorted or stretched vision. People with astigmatism will see numbers in both the **cylinder** and **axis** columns of their prescription. These values indicate the degree of correction needed for the curvature of your eye.
### Bifocal and Progressive Lenses
If you need multifocal lenses, such as bifocals or progressives, your prescription will include an **ADD** value. Typically, these types of prescriptions are recommended once you reach your 40s, though there are exceptions. Bifocals or lined bifocals correct for both distance and reading, whereas progressive lenses offer corrections for distance, intermediate, and reading—all within a single lens.
With all this in mind, the big question remains: how often should you get an eye exam? Generally speaking, we suggest having a comprehensive eye exam every one to two years to monitor your vision and overall eye health. If you start noticing changes in your vision—like needing to hold objects closer or farther away than usual—or experience frequent headaches, these could be signs that your prescription needs updating. In such cases, it’s wise to consult with an optometrist for a professional evaluation.
Even if you have a fresh prescription, high-quality frames—like those from David Kind—can last you for several years without needing replacement. If you already own a pair of David Kind frames and just require new lenses, you can easily update them. And if you’re unsure about your current prescription or which frame would suit your needs best, feel free to reach out to our team. We’re always here to assist!

Car refrigerator, as the name suggests, is a refrigerator designed for vehicle use. Its main characteristics include small size, light weight, low power consumption, and can adapt to the bumps and vibrations generated by the vehicle during driving. There are usually two types of car refrigerators:
1. ** Semiconductor car refrigerator ** : This type of car refrigerator uses semiconductor materials for refrigeration and does not require a compressor, so it has low noise and long life. However, its cooling capacity is relatively weak, and it is suitable for keeping food or drinks low temperature, rather than for cooling them down substantially.
2. ** Compressor refrigeration Car refrigerator ** : This type of car refrigerator uses compressor refrigeration, has a strong refrigeration capacity, can reduce the internal temperature to a very low, and even can be kept frozen in the hot summer. However, due to the need for compressor work, so this type of refrigerator is relatively more power consumption, noise is larger.
The car refrigerator is ideal for long trips, camping, picnics and other outdoor activities, and can easily carry and preserve food and drinks. When choosing a car refrigerator, you can decide which type of car refrigerator to buy according to your personal needs (such as refrigeration capacity, capacity size, power consumption, etc.).
