TIPS
Much like bifocal glasses, progressive glasses allow wearers to use two different types of lenses — one for viewing objects in close proximity and another for viewing objects that are far away. This versatility is ideal for anybody who experiences presbyopia. Progressive lenses are different from bifocals in a few ways, though. These differences make many people prefer progressive lenses for safety glasses.
Progressive lenses are far more contemporary than bifocals — they were invented in 1959. The invention sought to correct some of the shortcomings of bifocals, they offer the following advantages:
– No distracting line demarcating lenses
– Wearers can comfortably see at any distance
– They may look more natural than bifocals
– Progressive lenses may be the better option for safety glasses if you work in an environment where you need to focus from a range of different distances.
Cons of Progressive Lenses
1) Some people have a hard time adjusting
2) The gradient prescription of the lenses can cause distortions
3) Progressive lenses are more expensive than bifocals.
These disadvantages are certainly worth considering, but they shouldn’t dissuade you from investing in a pair of safety glasses with progressive lenses. These glasses can improve your sight, which will minimize the risk of workplace incidents.
Bifocals are two different lenses. The primary lens — which is typically on top — allows the wearer to see more clearly from a distance. The secondary lens — which is typically inset at the bottom of the main lens — allows wearers to see more clearly at a close range. This is especially helpful for reading.
There’s a reason why bifocal lenses are so popular. They come with many benefits. Some of the most appealing advantages include the following:
1.) Enjoy the convenience of one pair of glasses
2.) Save money compared to other types of glasses
3.) Adjust to new lenses more easily and quickly
4.) These pros make bifocal lenses a great option for anybody who’s seeking a simple solution to complex vision problems.
Cons of Bifocal Lenses
Of course, there are many reasons, too, why you may not want to opt for bifocal lenses. Some of the disadvantages of this lens style include:
1.) The bifocal line may be distracting or annoying
2.) Your vision may be distorted as you adjust to the lenses
3.) The adjustment period may be difficult for some
4.) If these drawbacks are enough to dissuade you from investing in a pair of bifocal glasses, you might consider looking into progressive safety glasses instead.
