Presbyopia is a natural phenomenon of declining eye function with aging. Due to the gradual hardening of eye lens and the aging of muscles in the eye, the zoom function of the lens deteriorates, making it difficult to focus and blur the vision field when looking at close objects. Most people begin to experience presbyopia around the age of 40 to 50, so people with myopia also have the chance to get presbyopia.

Multi-focal lenses are mainly used for people with presbyopia between 40 and 50. If you feel that presbyopia affects your normal life and you need to wear reading glasses while reading, multi-focal lens implantation is a good choice for you. Again, the most suitable presbyopia correction plan is needed to be tailored by ophthalmologists after a comprehensive examination and assessment.

Optically, presbyopia is a type of hyperopia, but they have different causes. The main cause of hyperopia is shortened eyeball that causes images to be focused behind the retina. As for the presbyopia, it is because of the degradation and hardened of the lens, the loss of elasticity and the aging of the ligaments connected to the lens, which reduces the focusing function of the lens. Therefore, it is difficult to focus on close object and easy to have blurry vision.

At present, there is no effective way to prevent presbyopia from appearing or worsening, but it is important to maintain good habits in order to alleviate the symptoms of presbyopia.

You can achieve good near vision and read without reading glasses on the next day after treatment. Mid and distant vision will usually be achieved within one week. Your vision will become clearer and gradually adapt to multifocal vision after a few weeks.
