Can I use my prescription for contact lenses?
You cannot and should not use your glasses prescription to calculate your contact lens prescription. It's important to note that not everyone who needs glasses can wear contact lenses, and it's important to check them separately. Some people have sensitive corneas or other eye complications and never get used to wearing contact lenses.
The disadvantages of progressive lenses
- The field of view in the near and middle distances is relatively narrow.
- The adaptation time is longer and patients with greater astigmatism are not suitable for wearing.

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.
