Why Do Replace New Lenses for Old Frames?

First, if your glasses frame is in good condition, glasses lens replacement is a good choice since it can help you to save money.

Second, if your eyeglasses have been part of your signature look for years, replacing the lenses with your new prescription is smart. Your family, friends, and customers won’t have to get used to a new you.


What Should You Do If Your Glasses Are Broken?

Professional eyewear repair shops have professional repair tools. It's relatively easy to fix the bent frame by yourself. Still, there are reasons to get a professional to fix them. Your local eyewear repair shop can quickly reshape metal and plastic frames and make sure they fit. Many professional optical shops will make small adjustments free of charge. The frame is completely broken and requires special tools and skills to fix. Frames are too fragile to repair at home, and trying to do so could cause even more damage to your frames. The lenses are damaged and you may need to replace them. Make sure your prescriptions are up to date. If your prescription is not up to date, you need to schedule an eye exam before changing your lenses.



Do all glasses come with nose pads?

The glasses without the nose brace are plate glasses. In reality, there is still a nose pad, but it is relatively small and it's part of the frame. The westerners have high nose bridges, and many glasses have no or very small nose pads. For example, Harry Potter's glasses have no nose pads. European and American brands will change their nose pads for the Asian market. Eyeglasses without a nose pad rely on the bridge of the nose to support the center beam. It's hard for Asians to stand up, and their eyes are more protruding than sunken like westerners. Glasses are usually demanded to keep a 12mm distance between the lens and the eyeball, otherwise, the optical performance will have a great impact.


Operation and Requirements of Drop Ball Test

The ball, which is 0.625 inches in diameter and weighs 0.56 ounces (16 grams), falls from 50 inches (127 centimeters) and hits the center of the lens. The geometrical center of the lens should be struck by the ball within a circle 5/8 inches in diameter. If the lens does not break, it is called a safety lens. There can't be anything that restricts the ball from falling. It cracks across the entire thickness, containing laminated layers (if any), and divides into two or more separate sections across the entire diameter.



The price of new lenses

The price of the new lenses depends on several factors, including if you have vision insurance. Another aspect to think about is that if your lenses need an anti-glare solution. If so, the lenses may be much more expensive. If you need eye exams and special lenses, the cost can be quite high. Scratched lenses are easier to repair. If you want your scratched lenses repaired by a professional, most opticians can pay very little.

The principle can be followed when choosing glasses for people with round faces

Choosing the right frames is not an easy task. Choose a color closer to your skin or lighter than your eyebrows for a more natural look. In reality, there is no exact answer to choosing glasses based on face shape. The rule to follow when choosing glasses for a round face is to make up for the lack of a round face by choosing an angular style. The vertical lines of the frame should be narrow.
