Regular visits to the ophthalmologist are essential to accurately assess your vision and get a complete diagnosis of your eye health. However, given that it is now common to spend more time at home, there is a vision test, based on simple exercises you can do on your own, to check whether you see well and detect signs that are all the more reason to see a specialist.<\/p>\n\n\n\n
Ana Gonz\u00e1lez, an optometrist at Miranza IOA, explains that one way to spot possible refractive errors, such as myopia<\/a>, hyperopia <\/a>or astigmatism<\/a>, is to use a pinhole. If, when looking through this small-diameter hole, you notice that you see better \u2013 first with one eye and then with the other \u2013, then it is probably a matter of focus. As the light rays passing through the hole and entering the eyeball are concentrated, the depth of focus increases and the refractive error is minimised. You can test this by building your own pinhole, punching a hole in an opaque surface, such as cardboard or a biscuit. Be careful though! If the hole is too big, it is no longer valid (for example, a doughnut hole would not work). Remember as well that it is always necessary to validate the diagnosis with an expert.<\/p>\n\n\n\n
