The natural shape and curve of your cornea and eye dictates how clearly you see. If they are shaped just right, you will have clear vision at all distances.
However, if your cornea is too steep or flat - or your eye is too long or short - you will end up with blurry vision at near, far or all distances. This is because the cornea is not allowing light to properly bend (refract) and focus on the retina (the back of the eye).
These irregular corneal and eye shapes are called refractive errors and they are very common:
The condition of presbyopia (the need for reading glasses or bifocals) is not a refractive error. By age 40, many people start to develop what they might think is farsightedness because they need glasses to read things up-close. Presbyopia is actually the stiffening of the natural lens that occurs gradually over time - even to people who have had 20/20 vision their whole lives. As the lenses become less flexible, it becomes harder to focus on images like text messages, restaurant menus, medicine labels and more without some type of magnifier.
LASIK cannot correct presbyopia. However, a technique called monovision LASIK, where one eye is corrected for vision distance and the other eye is corrected for up-close vision, may be an alternative to reading glasses or bifocals.
While LASIK can help many people achieve clear vision, it is not recommended for everyone.
