Myopia, commonly known as near-sightedness or short-sightedness, is an eye condition in which light focuses in front of rather than on the retina. As a result, faraway objects appear fuzzy, while nearby objects appear normal. Another symptom that might occur is headaches or eye strain.
Options for spectacle Lense
Short-sighted people, often known as myopic people, have a tendency to have their vision deteriorate or worsen with time. Myopia control, commonly referred to as myopia management, is a method of decreasing the growth of myopia. Spectacles are usually the initial kind of vision correction for a youngster who has developed myopia (glasses). A myopic youngster may require the following types of spectacle lenses:
- Single Vision -they only address the problem of long-distance vision.
- Myopia control spectacle lenses-a visible line in the middle, with the top half of the lens adjusting for long-distance vision and the bottom half correcting for reading vision
- Progressive addition lenses (PALs)- are similar to bifocals but do not have the line. They have a constant power mix from the top of the lens (far distance vision) to the bottom of the lens (near distance vision) (reading vision). These are worn by many individuals over the age of 45, and they can even be worn by children.
- Specific lens designs- Peripheral plus and multisegment designs are examples of this.
Spectacle lenses to prevent the progression of myopia
According to data from a 2-year clinical experiment given at the 2016 Association for Research in Vision and Ophthalmology meeting, aspheric lens lets in spectacle lenses, commonly known as Essilor Stellest lenses, were found to dramatically reduce myopia development and axial elongation in children.
HALT technology is used for stellest lenses, it consists of a constellation of spherical lenses across 11 rings which in return generates volume of signal slowing the elongation of eyes
What’s New in Myopia Management Spectacle Lenses?
Until 2010, progressive addition or bifocal glasses were the sole options for managing myopia using spectacles. Although under-correction was commonly used, it has been found to accelerate myopia development. In several nations, bifocals with and without a base-in prism reduced myopia progression by roughly 51% (spherical equivalent) when compared to single-vision glasses.
Conclusion
Your eye care practitioner will be the best judge of which option is appropriate for you since it will depend on your level of myopia, eye muscle coordination, age, and other considerations.
