Progressive Vs. Bifocal Lenses- How Are They Different?

Sunglasses as a Fashion Tool

Glasses form an essential part of fashion nowadays. Different styles and designs are available to suit every occasion, from weddings to daily wear. If you look around outside your home, you may find ninety percent of the people wearing sunglasses or, in the millennial language, ‘shades.’

Sunglasses have also transformed into various forms. They now come with optical lenses that help protect your eye from damage because of UV light and also allow you to see clearly. The variety of colors and shapes is another attraction to fashion addicts.

The latest evolution in the sunglasses world has been the integration of sunglasses with a camera. This update has been popular in the detective or spy world for the cause of security etc. However, sunglasses with a camera are also used for leisure, allowing you to record your special moments while enjoying them to the fullest.

Optical Lenses

Optical lenses are concerned with eyesight correction. Many people experience damage to the macula in their eye’s retina that causes blurry vision. Eyesight power is measured on a scale up to digit six; its worst cases are counted in negative.

Eyesight issues may cause a blurry distant, or closer view. In each scenario, the lens used differs, and so is the precautionary measure. Optical lenses are chosen for individuals after careful inspection of their eyesight power, and a corresponding number of lenses is given to them.

These lenses can be added to the glasses’ frame or used as contact lenses. Whatever the form, the purpose remains the same, i.e., improving the resolution of visuals you get from your eye.

What are Progressive and Bifocal Lenses?

Progressive and bifocal lenses are focused on distant and near image perception. These lenses provide you with a single solution to your resolution problems. They are available at local optician shops on the prescription of doctors.

Progressive vs. Bifocal Lens

Progressive lenses provide both far and distant vision within the lens, while bifocal lenses have a distinct line between far and distant perception. Both types are used for comfortable images in the condition of presbyopia. The use of these lenses depends upon your routine and preferences.

Progressive Lenses

As mentioned earlier, progressive lenses deal with far, intermediate, and close vision within the lens. They have a broader vision spectrum as compared to bifocal lenses. This helps in better vision when you have a high screen time. For example, people with computer-based work might find their vision clearer when wearing progressive lenses. The lenses have transitioned from slightly blurry to crystal clear vision for active users.

Bifocal Lenses

Bifocal lenses sharply distinguish between distant and closer views within the lens. You can feel the change when focusing on a distant object and then a closer object. Although a wider population chooses progressive lenses due to their broad spectrum, bifocal lenses might also be suitable for some uses. Users with slightly fewer vision needs or problems find it comfortable to deal with the distinct vision between closer and distant images.

Comparison Table Between Progressive and Bifocal  

The difference between the progressive and bifocal is very meek, but the users can feel it when they incorporate the lenses into their daily use. The comparison table will help you decide which lens is more suitable for your routine, use, and comfort.

Lens choice is one of the most complicated choices to make. People need clarification on the different options and may choose the wrong option in chaos. However, homework before heading to the optician shop would help one make the right choice. Always select the lens that suits your daily use instead of being charmed by fancy showcasing. Do a basic search about what lenses are suited for what use and choose the correct option. Book readers might find bifocal lenses easy to choose progressive and bifocal lenses, while computer workers may find progressive lenses more comfortable.
