3. Cataracts
Studies have shown that almost half of all Americans will either have a cataract-removal surgery or cataracts present in their eyes by the time they hit the age of 80. With the high frequency of cataracts, doctors have been looking into the various complications they can cause. Farsightedness is one of them. Your cornea is the part of the eye responsible for focusing incoming light and sending it to the retina.
If the cornea is obstructed by the dense and cloudy cataract then it will send blurred light instead of focused light. This is the mechanism in which farsightedness occurs in patients with cataracts. That being said, the farsightedness typically goes away soon after the cataract is removed. As of now, the preferred method for treating cataracts is surgical excision, but doctors have spent the past few years looking for other viable treatment options that pose less risk.
