What is a progressive lens?
A progressive lens is a lens whose upper sides are used to see far, and the lower side is used to see near. The distance from the fixed distance power above the lens to the near power fixed below the lens does not change suddenly, but a gradual transition between the two through the gradual change in refractive power.
Standard progressive lenses are multifocal lenses with three observation areas, farsightedness, intermediate vision, and nearsightedness. Unlike bifocals, there are no visible lines between each viewing area. They have a seamless, invisible design, where the optical power changes 'gradually' throughout the lens. Many people confuse 'bifocal' or 'trifocal' with 'progressive' but remember that bifocals and trifocals have visible lines in the lens, while progressive lenses do not. Because progressive lenses have no lines in the lens, they are more popular multifocal lenses than bifocal lenses. However, is progressive lens good for eyes?

What factors make you receive glasses on the same day?
Are your lenses anti-glare or anti-scratch? This may extend the time it takes you to buy glasses. Is your prescription complicated? If so, it could mean your lenses take longer to make. Your favorite frames that you tried out at the store are just for display, so you have to order frames for your glasses. If that particular frame style is in small quantities at the factory, your delivery may be delayed. Some optometrist offices and eyewear retailers have in-house optics LABS. These LABS can make some eyeglass lenses in an hour or so. But the power and design of the other lenses needed to be manufactured by an external optics lab, which took more time.
