What Is A Progressive Lens
Progressive lens is a kind of optical glasses lens used to correct distance, middle (computer use) and near distance (reading use) at the same time. They are also called progressive addition lenses because when you move the lens down, the distance prescription is at the top and gradually increases your vision.
You should think of progressive lenses as wireless bifocal lenses. Advances have made the transition between the glasses smoother, eliminating the lines of clearly different prescriptions between the sides of the lenses. This technique can help you see better in more instances.
The price of each progressive lens varies greatly. PAL tends to be more expensive than others because you actually combine three lenses into one. Cost depends on several factors, many of which are well mentioned in this guide. One of the most important factors is the type of progressive lens you get. The lens material will affect the cost of the lens-the material used for PAL will also determine the price. Standard plastic lenses are thicker, heavier, have less scratch resistance, and are not as shatter-resistant as other lenses. They are often the cheapest because the quality is not very good.
Advantages and disadvantages of progressive lenses:
Digital PAL is more expensive, but more personalized, specific to your measurement, which is the key to providing the best visual experience. Traditional surface and professional lenses tend to be cheaper than digital lenses, but more expensive than the "basic" PAL, which has a narrower corridor towards the bottom.
