Having A Hard Time Reading Since You Are 45? … Welcome To Presbyopia

Presbyopia analysis
Are you finding that you are moving your phone closer to you and then even more away looking for the sweet spot where the text is clear? Do you have the text size on your phone magnified to the largest size? Do you need to draw your head back when your kid places something in front of your face to read? If you responded yes to these inquiries you are most likely developing presbyopia.

Presbyopia is a normal aging change of the natural crystalline lens, which rests right behind the pupil within the eye. When we are young, this lens has the ability to alter shape to focus from distance to near. As we age, this lens hardens. Eventually, when we cross age 40, this hardening reaches a point that we find ourselves holding things more away from our eyes to maintain clarity while reading as the hardened lens is not able to adapt or change shape to help in focussing up close. Eventually, points are still blurry when we hold things at arm’s length and then we need to remedy this. This is when we go on to reading eyeglasses or bifocals to help. As we continue to mature, the strength of these reading glasses or bifocals will need to increase in power till around age 60 when our prescription normally will plateau.

Unlike near-sightedness, farsightedness and astigmatism, presbyopia does not differentiate. At some point we will certainly all succumb to its power and be forced to do something to maintain vision quality with our near vision. There are several alternatives, which are described below.

Reading Glasses/Readers
Reading glasses are a great option for people that have actually been bestowed with excellent vision both far and also up close through their first couple of decades of life. When they start to observe their failure to focus up close like they used to, they are most likely to run to the departmental store and grab a set of reading glasses. They will observe that when they put them on, things past the end of their fingers such as the television across the space will be blurry. Commonly individuals will find that they actually have reading glasses scattered around your home as well as at the workplace to guarantee that a pair is always at hand when required.

Bifocals
Bifocals are a natural change for those that already wear glasses to remedy their vision. The lenses are created in a way where there is a raised power in the lower section of the lens to provide the capacity to focus on near things. Conventional bifocals have a line in the bottom third of the lens that indicates where this reading power is located. Some will certainly transition to a trifocal that has two lines indicating a focal point for distance, intermediate as well as near tasks. One of the most usual lenses, called progressive lenses give a distance improvement in the upper part of the lens and after that have a progressive transition as you move down the lens with increasing quantities of power, peaking near the bottom for optimum near vision. These modern lenses do not have lines like conventional glasses and also trifocals. They also give a better range of clear vision than glasses or trifocals.

Monovision Contact Lenses or LASIK
Both contact lenses and also LASIK can remedy one’s vision to make sure that one eye is focused to see best at distance and one eye is focused to see ideally up close. With this kind of improvement, there is a sacrifice in final clarity compared to when both eyes are made use of for distance or near tasks. Nevertheless, monovision provides freedom from having to use eyeglasses for most activities. Lots of people adjust well to this type of vision. The benefit of LASIK in this type of correction is that it also gives freedom from having to put contact lenses each morning and then remove them each evening. Some patients that do monovision with contact lenses or LASIK will have a pair of glasses that they use to remedy their distance vision eye for tasks such as night driving, where they desire the most effective distance vision possible. They may also have a set of glasses for prolonged durations of reading.

Multifocal or Extended Depth of Focus Contact Lenses or IOLs
An additional option to correct presbyopia consists of multifocal contact lenses, multifocal intraocular lenses (IOLs) or expanded depth of focus intraocular lenses (IOLs). Multifocal contact lenses as well as IOLs divide the light that goes into the eye to either focus at near, intermediate or distance focal points. This splitting of light does break down the quality of vision somewhat, however most individuals are fairly tolerant of this. The benefit of IOLs is that they get rid of the insertion each morning as well as removal each night that is required for healthy and balanced wear of contact lenses. IOLs are also placed in a fixed position within the eye, where the natural crystalline lens is located. Whereas contact lenses move with each blink a person makes. This allows IOLs to provide an extra stable, normal vision than that given by contact lenses.

Extended depth of focus IOLs allow the focal points to be lengthened to enhance one’s intermediate and also possibly near vision. These lenses don’t split the light in between various focal points; therefore, they provide a higher quality of vision than multifocal lenses. However, this enhanced quality of vision does give up some of the near vision that is provided by multifocal lenses.

Khanna Vision Institute concentrates on the surgical treatment of presbyopia with monovision LASIK, multifocal IOLs and extended depth of focus IOLs. We would love, if you schedule a free examination to see if one of these alternatives may help you decrease your dependence on eyeglasses or contact lenses.
