Bifocals are eyeglasses that feature two lens powers, allowing wearers to see both near and far objects. In the past, individuals with bifocal vision had no choice but to wear special glasses or contact lenses in order to correct their vision. However, LASIK (Laser-Assisted in situ Keratomileusis) can now free them from this dependence on eyewear. This procedure uses a laser beam combined with sophisticated computer technology to reshape the cornea of the eye, correcting refractive errors like nearsightedness, farsightedness, and astigmatism. It is important for patients considering LASIK who use bifocals to understand what they should expect before and after undergoing surgery as there are certain factors that need to be taken into account during evaluation for eligibility for this procedure.
As people age, their eyesight may deteriorate. Factors such as genetics, environment, smoking, high blood pressure, and prolonged digital screen use can speed up this process.
