Eyeglass options have come a long way in recent years. Prescription eyeglasses are specially designed to correct and improve vision clarity, protect the eye from workplace strain or injury, and support lifestyle choices. Here’s a look at the most common types of prescription eyeglasses available today.
Single Vision Eyeglasses
Single-vision eyeglasses have a single prescription power across the entire lens. They are commonly used to correct either nearsightedness, also called myopia, which means you can’t see far objects, or farsightedness, also called hyperopia, which means you can’t see near objects. Both myopia and hyperopia are conditions that can occur at any age. These glasses are ideal for tasks such as reading, driving, or watching TV.
Bifocal eyeglasses have two distinct areas in the lens with different prescription powers. The upper part of the lens is for distance vision, while the lower segment is for near vision. They are commonly prescribed for individuals with myopia as well as presbyopia, a condition that affects near vision in middle-aged and older adults. Presbyopia is caused by the loss of elasticity in the lens of the eye, which affects its ability to change shape and focus.
Trifocal eyeglasses have three areas in the lens with different prescription powers. Similar to bifocals, the upper part is for distance vision, the middle part is for intermediate vision, and the lower segment is for near vision. Trifocal eyeglasses may take some time to adjust to, as the wearer needs to learn how to shift their gaze and use the appropriate portion of the lens for different distances. These glasses are recommended for individuals who need clear vision at multiple distances.
Progressive eyeglasses are like bifocals or trifocals, but they don’t have an obvious line dividing the different segments of the lens. They are a popular choice for individuals who require multi-focal correction but prefer a more modern, seamless appearance without distinct lines.
Computer eyeglasses are designed specifically for people who spend long hours in front of a computer screen. Computer eyeglasses can help reduce eyestrain and discomfort caused by prolonged screen use. These glasses have a modified prescription that optimizes vision for digital displays, minimizing symptoms like headaches, blurred vision, and dry eyes. Computer eyeglasses can make working on a computer far more comfortable.
They are available in various strengths and are typically used by people with presbyopia, which is the inability to focus close up that comes with normal aging. These glasses are not meant to correct astigmatism or other vision problems and should be used only for reading or close tasks, such as needlework.
For individuals who work in hazardous environments, safety glasses are essential. Safety glasses are designed to protect the eyes from potential hazards in the workplace, such as flying debris or chemicals, and can be customized with prescription lenses for vision correction. They are made from impact-resistant materials and often have added features like side shields and UV protection. Safety glasses can be made with prescription lenses to provide vision correction along with eye protection.
Sports glasses are designed to enhance vision during sports activities and protect the eyes from potential injuries. They are made from durable materials and often have features like wraparound frames and impact-resistant lenses. Sports glasses can be customized with prescription lenses for optimal vision correction while playing sports.
Prescription lenses can also be customized with additional features, such as anti-reflective coatings to reduce glare and UV protection to shield the eyes from harmful UV rays. These features are especially beneficial for people who spend a lot of time driving or outdoors.
