How do people with astigmatism see Christmas lights?
Most people with good vision have eyes which are perfectly round, which means that their eyes focus light well onto the retina. People with astigmatism have eyes which are shaped more like a football than a soccer ball, meaning that light which enters their eyes is distorted by the abnormal curvature. This leads to the image not focusing properly on their retinas, producing a blurry and distorted image.
Astigmatism is typically diagnosed at an eye test with your optician. There are a number of factors that increase your likelihood of experiencing astigmatism which include; a strong prescription (either short or long-sighted), thin corneas, family history of astigmatism, or corneal scarring from surgery or an eye injury.
If you have astigmatism, it’s likely that lights may appear:
Streaky
Blurry
Fuzzy
Surrounded by glare
Surrounded by halos
This is because, at night or in dim light, your pupil dilates in order to allow more light into the eye. As it dilates and grows large, more peripheral light enters your eye. The main effect of this is increased blurring and glare resulting in fuzziness, particularly around lights. When it comes to Christmas lights, it may be that you struggle to see the individual bulbs or lights on a string, instead seeing a general blur with all the lights merging together.
If the above description of lights sounds familiar to you, then it’s possible that you have astigmatism. Thankfully, astigmatism isn’t an eye disease – it’s simply a refractive error, a bit like being long-sighted or short-sighted. This means that it can be rectified with a number of solutions, including glasses, contact lenses, or eye surgery.
If you think you might have astigmatism, or if you just want a comprehensive exam to check the health of your eyes, give Dr. Hassinger a call at 727-202-3812 to schedule an appointment.
