The most common reason for the eyes not being able to focus at a distance is refractive. Refractive causes include myopia, hyperopia and astigmatism problems, the most common being myopia. If you can’t see clearly at a distance, you should first go to the hospital for an optometric treatment to check whether there is a refractive problem. If the problem is indeed caused by refractive problems, you need to use glasses to correct your vision and achieve the effect of seeing clearly at a distance. However, if refractive problems are ruled out, there may be problems with organic eye pathology, such as keratitis, cataracts, or problems with the fundus of the eye. If there are such problems, you need to visit an eye specialist to treat these problems in a timely manner. After these problems are corrected, vision may be improved to varying degrees, so be sure to get checked out according to your situation. In addition to the possibility of strabismus, patients with intermittent exotropia often show a pronounced exotropia when looking at a distance, with poor visual function in both eyes and a subjective feeling of inability to focus.
