An unbroken set of horizontal curves in a progressive lens connects far vision, intermediate vision, and near vision with no perceptible distinction. Lens power gradually increases from the top of the lens to the bottom, passing through an intermediate vision area in the centre and a near vision area. Many clinical investigations undertaken over the last 20 years have proved the advantages of progressive addition lenses for treating presbyopia over bifocal and single-vision reading lenses.
Progressive lenses more expensive than standard lenses
Progressive lenses are more expensive than single and bifocal ones but given the convenience and simplicity of the lenses, it is worth the money.
Takes some time to adapt to them
It can take some time for our eyes and brain to see clearly at a distance and a close-up when we start using progressive lenses. Most people adjust to their new lenses in only a few days but for some, it could take up to a few weeks. It is advisable to wear them full-time for two weeks to get adjusted to them. At first, you may suffer from blurry vision and a mild headache.
One pair of glasses for different purposes
Progressive lenses allow you to see all distances with one pair of glasses. Simply shifting your head position allows you to concentrate on different sections of the lens. Move your head upwards to view things in the distance, straighten it for intermediate or arm's length vision, and down for close-up vision.
Modern and Youthful Lens
People might be slightly self-conscious about wearing bifocal lenses due to their association with old age, especially when they are young. However, progressive lenses look just like single-lens glasses and don't follow the same stereotypes that are associated with bifocal.
The appropriate care of the eye is an important part of the lifestyle; wearing progressive lenses correctly can increase your chances of improving your eyesight.
