Tips About Contact Lenses for Presbyopia

By Sebastien Baccon

Contact lenses for presbyopia


Presbyopia is vision problem in which the eyes are not able to focus clearly on objects that are near. Unlike myopia that can affect people at any age, presbyopia mainly affects people at the age of 40 years and above. Presbyopia mainly occurs due to the stiffening of the eye's lens which occurs as one becomes old. You may have noted that most people at the age of 40 years and above complain of having difficulty in reading, difficulty in seeing in low lighting conditions and occasional headaches. This is due to inability of the lens to adjust to different shapes to aid in perceiving objects that are in different directions. This condition can be corrected with the help of contact lenses for presbyopia.

The most commonly known solutions for presbyopia are reading glasses and bifocal lenses. However in the modern world, most people prefer to use contact lenses for presbyopia other than reading glasses. There are three distinctive ways by which contact lenses for presbyopia can be used to correct presbyopia. However each of these ways has its advantages and disadvantages for particular types of patient. The optician needs to take some eye check ups and tests to help you know which way is best suited for your eyes.

Monovision is one way of solving presbyopia which involves the use of one lens for seeing near objects on one eye and in the other eye a lens for seeing distant objects. This method depends on how the brain processes and combine information from the best available sources in order to provide you with the clearest possible vision. The use of bifocal contact lenses for presbyopia is another way to solve presbyopia. One may choose to have one lens for viewing things that are far away and the other lens for viewing objects that are near.

Multifocal contact lenses for presbyopia work in a similar way as the progressive. These lenses are characterized by some zones of different power so as to aid the eye in the gradual changes to focus on different objects at different distances. These are the main ways in which you can solve presbyopia. Presbyopia cannot be avoided since it is a condition that progresses throughout one's life as we age. The only thing that you can do about presbyopia is managing it using contacts for presbyopia especially if you begin to experience this condition at the age of 40 and above.

Contact lenses for presbyopia cannot be purchased without going through some eye check ups by an optician to ascertain that you need these lenses.

The advancement in technology has lead to the manufacture of lenses for presbyopia of different types such as disposable or frequent replacement varieties depending on the needs of the consumers.

Today these are very popular lens types providing obvious benefits for people suffering from presbyopia. With good quality of contact lenses for presbyopia, one is able to overcome this challenge and live a normal life just like other people without this eye condition.

How Do Contact Lenses Work?

By Maria Gonzalez

Contact lenses rest on your cornea atop a constant supply of tears. The contacts are also held in place by pressure exerted from the eyelids. When you blink the pressure from the eyelids cause the contacts to move slightly and glide over your cornea. This allows the tears underneath to gently flush out trash or debris that may have accumulated in your eye.

This is just how the contact stays on the eye and is able to provide a way to correct vision. The way the vision is corrected is a different story altogether.

Contact lenses are prescribed to a wide variety of individuals who have vision problems associated with astigmatism, nearsightedness, farsightedness, and presbyopia. The retinas of individuals who suffer from these conditions cannot properly focus light. When the retina does not function properly and/or does not properly focus light then the result is imperfect and blurry vision.

Contact lenses are made differently depending on the eye condition they are trying to correct. For instance, if you suffer from astigmatism your optometrist will measure your cornea so a contact can be made precisely to fit your eye. By doing this a contact is made that will fit your eye perfectly and direct light rays to one place on the cornea, which in turn corrects your vision.

Those suffering from myopia, also known as nearsightedness, will wear lenses that are thinner in the middle and thicker on the edges. This design allows the light rays to be processed correctly by the retina.

Farsightedness sufferers are prescribed just the opposite contact lens, but with the same end result. They allow the retina to process light correctly as well, resulting in corrected vision for the wearer.

All contact lenses use the basic technology to correct vision for the wearer. They redirect light to the retina so it is processed correctly. The only difference is contacts are made differently to treat different eye problems.
