Presbyopia is a common vision condition that begins around the 4th decade of life and affects many people. Presbyopia occurs when the natural lens inside of the human eye begins to harden and lose elasticity. As the crystalline lens loses flexibility, the ability to change focus from far to near begins to deteriorate. Difficulty reading things up close and having to move reading material farther away in order to see are just some of the symptoms associated with presbyopia.
In the past, many people resolved this problem through the use of glasses with line-bifocals and/or readers aka “cheaters.” As a result, the use of line-bifocals or cheaters has become synonymous with the words “old age” and “grandparents.”
However, with the development of new lens technologies, we now have the lens options to help you maintain the appearance of youthfulness as well as maintain good, functional vision.
Progressive Addition Lenses (also known as progressive lenses) have multiple points of focus at different parts of the lens. The different segments allow for clear vision at distance, intermediate, and near. A progressive lens is sometimes referred to as a “no-line bifocal,” because the transition between power segments is not demarcated with a line.
Progressive lenses are especially great for people who don’t want to have to alternate between multiple pairs of glasses for each task and for those who want don’t want to bother taking their glasses on-and-off for specific tasks.
New progressive lens technologies are constantly in development and are released every couple of years. With each new lens design that is released, the corridor (window) for viewing is widened and the peripheral distortion is decreased. As a result, vision through the progressive lens has been improving with each new lens design.
Innovations in the contact lens industry has led to the development of many types of comfortable multifocal contact lenses. Multifocal contact lenses are for people who prefer the convenience of wearing contacts over glasses. Although glasses are currently “in fashion”, there are certain occasions, such as when exercising, when contact lenses may be more convenient and comfortable.
With the advent and integration of digital devices (computers, laptops, tablets, smart phones) in our personal and work lives, digital eye health has become increasingly important. In order to maintain good vision throughout your life, we need to make sure that your retinas are protected against harmful light.
LEDs are commonly utilized as the primary light source in electronic devices, headlights, and overhead lighting in stores and workplaces. Studies on harmful blue-violet light have suggested that blue-violet light damages the macula and speeds up the process of macular degeneration. Macular degeneration is a devastating disease that causes loss of central vision.
Anti-reflective coatings with blue light protection have been developed to decrease the amount of harmful blue-violet exposure in effort to slow down the process of macular degeneration, thereby preserving vision for longer.
