Why do you need night-driving glasses?
Aging causes our pupils to become progressively smaller, so they don't dilate as quickly. A smaller pupil means less light reaches your retina, which makes it harder to see at night.

For people wearing prescription glasses, the risk of driving at night is much greater. Driving can be stressful, especially if you have poor eyesight. This is especially true at night.

Why choose an acetate frame?
(1) Lightweight and comfort
As one of the daily necessities, the lightweight acetate frame will not bring a heavy burden to the bridge of the nose. Even if you need to wear glasses all day, you will not feel too much discomfort.
(2) Durability
This is the key factor that makes acetate frames stand out from traditional plastics or other materials. Acetate frames are made by cutting, molding and polishing multiple pieces of material, which makes them as strong as metal and ideal for eyeglass frames.
(3) Various design
The cellulose acetate spectacle frame design is the most fashionable. The surface layer of the traditional plastic frame is usually sprayed with colors and patterns. It may have a nice design or color. But because it is the only surface, daily use will cause its surface color and pattern to fade. After a year or even a few months, their appearance may not be as good as before. Unlike plastic spectacle frames, acetate makes the design easier to retain. The acetate fiber sheet can be designed with colorful patterns, different layers, and many colors. The embedded design can maintain its characteristics more effectively without spraying or painting.
Acetate is comfortable, weight-light and fashionable, and meets all your needs. Therefore, it can be said to be the best material for making spectacle frames. Therefore, the next time you decide to buy a new spectacle frame, please consider using a spectacle frame made of acetate.

Once a contact lens prescription is established, you are entitled to a copy. In some cases, this may occur after a diagnostic match. In many typical GP lenses and special designs, such as bifocal, annular, keratoconus, or postoperative, it may take several examinations before a successful match can be made and a prescription can be provided. If contact lenses are not issued by a doctor, it is important that whoever dispenses them is completely accurate. A soft lens Rx usually includes lens material name, design, power, base curve, and diameter. GP lens prescriptions usually have this information and more, like perimeter curve radius, center thickness, special perimeter design, and optical area diameter.
