Near vision after cataract surgery can be improved with prescription glasses or choosing (before surgery) bifocal or multifocal intraocular lens (IOL) for implantation during cataract surgery. It is a well-known fact that your near vision becomes poor after cataract surgery. This almost always happens when a monofocal intraocular lens (IOL) has been implanted during cataract … Read more
Bifocal glasses have the lenses with two powers meant for near vision and distance vision. The upper segment of the bifocal glass has power which corrects distance vision. The lower segment of the glass corrects near vision. When we read something, for instance, we look down and see through the lower segment of the glasses. … Read more
The term ‘reading glasses’ is used for glasses which are used for near work including reading. The power of the lenses in the reading glasses may exclusively be only for near work or the glasses may have lenses for both distance and near work (bifocal or progressive reading glasses).

This will be very useful to the people who don’t want to use bifocal or progressive glasses. The lenses in the glasses are flexible and can change shape – they … Read more

Presbyopia is a condition of middle-age in which near vision becomes poor. It is usually corrected with glasses. The newer treatments are aimed at getting rid of glasses. Corneal inlays are tiny implants which are inserted into the cornea changing its shape and refractive power. Raindrop inlay is one such example. A gel-like device that … Read more
We need reading glasses to correct presbyopia. Presbyopia is a condition which appears around the age of forty years in which distance vision is good but objects at close distance are blurred. This condition is related to age and is clinically similar to hypermetropia (far-sightedness) which is found in younger age group. Click here to … Read more
In a traditional cataract surgery, the opaque natural lens is removed and it is replaced with an artificial lens. The power of these intraocular lenses (IOL) is individualized and calculated before the surgery. The power of the lens is meant for vision for distance only. For all the near work, which includes reading, to see … Read more
