A team of experienced eye care professionals provides comprehensive eye examinations. It offers high-quality lenses and a wide selection of stylish frames.

By utilizing the most advanced diagnostic technologies, they are committed to improving the quality of life through enhanced vision. The optical studio has a range of carefully designed frames and precision lenses. There are many lenses to choose from. Transition lenses are made from dynamic materials and can replace prescription sunglasses. UV-coated lenses can be used in ordinary glasses. Scratch-resistant coating is a clear coating that helps protect glass lenses from irritating scratches. The plastic lenses make the glasses much lighter than the glass ones. Special polycarbonate lenses greatly reduce the thickness of the lenses, giving them a more attractive silhouette. Anti-glare lenses are dipped in a special material that makes them less reflective than regular eyeglass lenses.


Single Vision vs Progressive: What Are Their Differences

With single vision lenses, you can also just use the center of the lenses to avoid prismatic effects if your prescriptions are very unequal for both eyes.

As for progressive vs single vision, they also have differences in frame selection. You will stick to frames when choosing progressive lenses that will provide you with a minimum height of 14mm from the point you are looking through the lenses into the distance to the point you are looking down while you read.

Besides the above differences, they are also some other differences between single vision glasses and progressive lenses. You can choose either one based on your needs. To choose glasses, Koalaeye glasses are recommended. They come in stylish and at a cheap price.



What is the best lens material?

Trivex is a special material from PPG. Compared with PC lenses, the refractive index is lower (only 1.53) but the Abbe number is higher (up to 45), which results in smaller dispersion and better image quality. At the same time, the impact resistance of the Trivex lens is 10 times higher than that of the PC. It is the only explosion-proof safety lens that can withstand external force twists and turns in the market at present.


The Pros and Cons of Shopping Glasses Online

Brick-and-mortar stores rely on a few or a dozen a day to make a profit, so the unit price is higher. Online stores have low costs. The profit can be made by volume, so the unit price is much lower. This is the advantage of online stores. The disadvantage of online stores is that it takes a lot of effort to get an optometrist, but optometrists have varying levels and attitudes. As a result, the prescriptions we get may not be entirely accurate. This can lead to uncomfortable glasses. The physical store glasses can try on. Choosing online glasses is not convenient.



How to adapt to progressive lenses?

People who are prone to motion sickness or have inner ear diseases may suffer dizziness, nausea, vomiting, and other symptoms due to their inability to tolerate the slight deformation of the visual objects, so they need to pay more attention when wearing them. For people who have not worn reading glasses before, it is not recommended to wear graded multi-focus glasses directly because their eyes will not be able to adapt quickly.


The hazards of rusty spectacle frames

The most common allergenic metal is nickel. Once allergy occurs, it can cause contact dermatitides such as redness, swelling, itching, and yellow water on the surrounding skin. Many alloy products in daily life contain nickel, such as coins, various alloy products, electroplated objects, spectacle frames, metal watchbands, belt buckles, artificial jewelry, underwear buckles, etc. Their direct contact with the skin will cause allergies to sensitive people. Therefore, the temples and nose pads are the parts that contact the skin with a larger area. In particular, the outer surface of the metal frame and the metal contain a large amount of nickel, which can cause rust spots and skin corrosion, and allergies through contact with the skin and the erosion of sweat.
