As we age, our eyes become less flexible resulting in close up objects appear out of focus. This eyesight problem is referred to as presbyopia. A set of reading glasses is likely all you need to correct this issue (If in case, you do not already wear prescription glasses). But in the event that you wear glasses, change to a pair of lens lenses or bifocals.

Bifocal Glasses

Lenses permit you to see things up close and far away they don’t have a place for items. Traditional bifocals have a stigma related to them. Bifocals, using the noticeable line through the center of the lens, has an inclination. Bifocals additionally have an issue with a picture jump when you change from looking at the bottom of the lens out to see close up things or outside the surface of the lens to find items in the space.

Progressive Lenses

Progressive adaptive lenses (or PALs) are also known as no-line bifocals. They have multiple focal areas based on where you look from the lens. This permits the user to see clearly at all areas — close, far, any space and intermediate between. Lenses using their various focal zones have a tendency to get a higher rate of adaptation in comparison with bifocals with their two different zones that are focal.

Details on Their Differences

Whether bifocals or progressives will be the better option for vision correction depends upon what your vision problems are and exactly what your optometrist recommends.

Progressive lenses are often prescribed for individuals with presbyopia. Presbyopia means a decrease in the ability of the eye. Just like everything else seems to deteriorate the old we get, the eyes’ lenses aren’t any different. With age, we lose proteins in our lenses which makes them become less flexible and more difficult. This lack of flexibility results in less focusing capability for our eyes, which explains why so many people over 40 begin to notice blurry vision and having to maintain shopping list or dawn paper to be able to read it.

For the people finding it difficult to view things from close up or from a distance, Bifocals is a better choice. These can take a longer time in getting used to because the top and bottom regions of vision correction are all so distinct. Progressives offer you such a smooth transition between both fields to give the eyes a more slow change when moving to close up watching, or vice-versa.

Conclusion

Progressives have a disadvantage in comparison to bifocals. The area of vision in PAL’s are distorted in contrast lined bifocals. Contemporary lens designs help to pick frames, even with a lens, may assist with the field of vision issue and reduce this issue.

However, your eye specialist can advise you whether progressives or bifocals are the best options for you. You should opt even though it can be tempting to do so without having the information of an optometrist.
