As you age, your vision changes. As a result, you may require corrective eyewear, such as bifocal glasses. If you find it difficult to read up close and observe objects from a distance, schedule an appointment with our eye care specialists at Salisbury Optometrist and consider purchasing bifocal glasses from us. Through this blog, you will learn about bifocal glasses.
What are bifocals, and how do they work?
Bifocal glasses are a two-in-one prescription eyewear. These types of glass comprise two lens powers offering optical correction for both long and short-sighted distances. The upper half of the lens is for long-distance vision, and the lower half is for the reading prescription.
Generally, the segments vary depending on the wearer’s requirements.
Bifocal glasses help correct presbyopia, a condition that occurs when the lenses of your eyes lose their flexibility. Generally, the lens becomes less pliable, and the eye finds it difficult to focus its sight from different distances. At times, the objects may appear blurry, and there is an overall difficulty in seeing. Furthermore, this eye issue has become more common among the older population.
How does it work?
When you buy bifocal glasses, they compensate for presbyopia and the natural degradation of vision that occurs with ageing. Generally, the lenses get divided into two segments, each with varying shapes and sizes. For instance, they can have a D-segment (also known as half-moon or flat-top), a round segment, or a ribbon segment. These portions address the correction of near-vision, which is located on the lower half of the lens.
By using the distance segment of the lenses, the wearer focuses on objects at a faraway point. Since these portions are typically on the upper half, the user only has to look up through the glasses.
When you focus on reading materials, the wearer should look down and look through the lower segments, which are engineered for this purpose.
Can we wear bifocals all the time?
Our experienced eye care specialists at Salisbury Optometrist advise people to regularly wear bifocal glasses until they can adjust to their new line of sight. For example, if you switch from regular glasses to bifocal eyeglasses, you need an adjustment period. Some basic activities, like driving, may appear and feel different with these types of glasses on.
The most imminent change that you need to get used to is switching between the two segments. Imagine you’re driving, wearing your bifocal glasses. If you check your gas gauge or speedometer, look through the lower bifocal segment. For road navigation, you should constantly adjust your eyesight to focus on the upper portion of the lenses.
Pros
Flexible Vision
One of the critical advantages of bifocal glasses is the flexibility they offer to your vision. Bifocal glasses are multifunctional, allowing you to switch between different pairs instantly.
Therefore, you should look straight ahead for normal distant viewing and downwards to read objects at a nearby distance. Generally, it will prevent you from needing to buy separate pairs of regular and reading glasses.
Seamless Transition
Bifocal glasses do provide an easy transition between near and far vision objects. It is entirely different from separate reading glasses. All you need to do is completely adjust your gaze to the perfect section of the lens to achieve exact focus. It makes your daily activities more efficient and smoother.
Convenience
Bifocal glasses do provide unparalleled advantages for individuals who require correction for both far and near vision. Whether you’re reading a book, performing steady activities on a computer, or driving for a prolonged period, you should rely on a single pair of bifocal glasses to meet your visual needs. In a word, it eliminates the hassle of constantly swapping between reading glasses and regular prescription glasses.
How to find the right bifocal glasses
Generally, bifocal glasses resemble ordinary eyewear, except for the thin line that distinguishes the vision zones. It’s better to select a pair that suits you best. One critical factor to consider is the type of lens, such as flat-top, round-segmented, or executive bifocal.
These categories describe the design of the bottom portion, which enables you to see nearby objects.
Before selecting the best lens to improve your vision, consider the overall look and feel of the frame. That involves choosing the right shape that complements your facial features. For example, round glasses typically suit individuals with sharp jawlines and angular features. At the same time, square glasses and rectangular eyeglasses are suitable for people with round-shaped faces.
Your preference is the best guide when you plan to buy bifocal glasses. You should always purchase a frame that is comfortable to wear and can also enhance your vision.
