People suffering from Presbyopia can now enjoy the benefits of contact lenses. They can get rid of thick glasses which have a line between them. Long ago people suffering from this disease used to wear thick glasses and there was no alternative for them. With the implementation of bifocal contact lenses people they gave retirement to their old thick glasses. People suffering from both nearsightedness and farsightedness can use these strong, soft and gas permeable lenses for getting rid of these troubles.
If you are reading some paper or viewing an object that is near to you, these lens will automatically direct the pupil of your eye and get the light refracted into the angle of retina so that you can have a clear view. When you are about to view a distant object these specially designed lenses will automatically divert the pupil to set to the lens and view distant object with great clarity. For many people wearing thick glasses will cause dizziness, headache eye fatigue and eye strain. For them these are like a timely gift.
Normal lens which you use for one purpose like nearsightedness of farsightedness will rotate with the blink of eye. Bifocal contact lens will never rotate as the bottom portion of them is added a little weight that sets them in a proper position. Whatever may be advantages of these, they can be gained only when you are ready to take care of their maintenance. They should be properly cleaned in time with the cleaning solution which you can get from any local supermarket, medical store and from any physician.
Now anyone suffering from astigmatism and Presbyopia can use this lens for having a clear view of all objects. When not in use these should be stored in the box provided along with cleaning solution. This removes protein storage, removes dust particles and adds wetness to the lens.
