Varifocals are a type of prescription eyeglasses that combine two or more lenses with different powers in one frame to correct multiple visual impairments, including nearsightedness, farsightedness, and astigmatism. They are also known as progressive lenses and multifocal lenses, and they provide a more natural, seamless vision compared to traditional bifocals.
Bifocals are eyeglasses that have two distinct areas for near and far vision correction. The top half of the lens is designed for distance vision and the bottom half for reading. The visible line separating the two areas can be a significant drawback for many wearers, as it can disrupt the appearance of the glasses and create a noticeable jump in the lens power when looking from one area to the other.
On the other hand, varifocals offer a more sophisticated solution by providing a continuous, progressive change in lens power from the top to the bottom of the lens. This allows wearers to see clearly at all distances with a smooth and seamless transition, eliminating the noticeable line and abrupt power change associated with bifocals.
Varifocals are designed to correct multiple visual impairments, including nearsightedness, farsightedness, and astigmatism. The top of the lens is used for distance vision correction, while the bottom of the lens is designed for reading or close-up work. The progressive change in lens power from the top to the bottom allows for a smooth and natural transition between distances, without the noticeable line or abrupt power change of traditional bifocals.
Additionally, varifocals provide the benefits of progressive lenses, which include a wider field of view and more natural depth perception compared to traditional bifocals. With varifocals, you can look up and see the world clearly in the distance and look down to read a book or use your computer without having to take off your glasses or switch to another pair.
Yes, varifocals can be good for your eyes. By providing a continuous and seamless vision correction, varifocals can reduce eye strain and fatigue compared to traditional bifocals, which can cause discomfort and headaches due to the noticeable line and abrupt power change. Moreover, varifocals can help to preserve your eyes’ natural focusing ability and reduce the risk of developing age-related visual impairments, such as presbyopia, which is the loss of near focusing ability that often occurs with age.
Yes, you can wear varifocals all of the time. They are designed to provide a complete vision solution for all distances, so you can use them for both daily activities and special occasions. However, some people may still choose to wear separate glasses for certain activities, such as driving or playing sports, as they can provide better visual clarity and eye protection for those specific tasks.
In conclusion, varifocals are a type of eyeglasses that provide a more sophisticated solution for multiple visual impairments, including nearsightedness, farsightedness, and astigmatism. They offer a continuous, progressive change in lens power from the top to the bottom of the lens, allowing for a natural and seamless transition between distances. Additionally, varifocals can reduce eye strain and fatigue and help preserve your eyes’ natural focusing ability.
If you think that you require varifocals, we would recommend to seek professional advice from an optician.
