Nobody likes to have poor eyesight. That’s a given. People develop poor vision due to different reasons. They might be fond of reading in dimly lit places, moving vehicles/objects, or even both. Or they may have spent a considerable amount of time staring at a screen, the glare gradually damaging their eyes. In treatment centers like RevereHealth.com, the aforementioned reasons are very common.
But what if it poor vision can somehow be inherited? There is conflicting evidence regarding this claim, but the answers can be eye-opening (pun intended).
Specific eye conditions have stronger genetic components than others. This includes farsightedness, nearsightedness, color blindness, and progressive retinal decline (retinitis pigmentosa). Dr. J.P. Lowery, pediatrics chief at the Pacific University’s College of Optometry. Near and farsightedness are more commonly passed down, especially if both parents have either condition.
Nearsightedness and farsightedness are classified as refractive errors. A study published in the journal Nature genetics claims to have discovered 24 new genes that may be associated with refractive issues as a whole. Over 8,000 people of Asian descent and more than 37,000 people of European lineage were observed. The study also shows that individuals possessing the genes are ten times more vulnerable to developing said refractive errors.
Furthermore, a group of British scientists observed 500 pairs who had their parental gene in 85 percent of nearsightedness and farsightedness cases, as well as 50 percent of astigmatism. These experts infer, in the simplest terms, that children are likely to suffer poor vision if both parents have it.
The bottom line is that bad vision is still not entirely genetic. Environmental factors still play a part. Anyone, visual acuity notwithstanding, can develop visual problems due to bad habits. It just happens that some conditions being largely hereditary double the trouble. What parents need to do is instill a sense of discipline in their children when it comes to taking care of their eyes. And yes, it includes watching T.V. from a safe distance, limiting video games or mobile phone use, and reading when there is enough light.
