Cataracts are quite common in older adults. Those who have experienced a lot of unprotected sun exposure, frequent smoking, or suffering from diabetes are more likely to develop cataracts, but they can truly happen to anyone. As such, you should keep an eye out for the following early signs of cataracts as you age.
Many cataract sufferers initially assume their vision is just worsening due to age. Your entire visual field may get a bit cloudier. You may have to move closer to the television to see it clearly, or you may notice that you can no longer read road signs from as far back.
Halos Around Light
Another early sign tends to appear when you are driving at night or attempting to read via lamplight. When you look at a light, or even past the light, you may see what looks like a ring or halo around that light. This occurs because the cataract is bending the light as it reaches your eyes, causing it to scatter.
Yellowing of Colors
When you look at something white or pale-colored, do you feel as though it has a yellow tint? Some people assume their items are actually turning yellow when it's really their eyes that are to blame. A good way to test yourself is to visit a store and look at T-shirts that are specifically labeled as white. If they look yellowish, you may have cataracts.
Usually, double vision due to cataracts happens in just one eye at first. You might see two images that partially overlap each other, or the images may be further apart. Some people notice this mostly when tired. When you're better rested, the less-affected eye is able to compensate for the worse one, negating your double vision.
Sensitivity to Glare
You might find yourself avoiding driving at night or looking at bright screens because the glare gets to you. Lounging in the sun may start to bug you, too, especially if you do not wear good sunglasses. Sometimes, the first symptom of cataracts may even be headaches due to glare.
If you notice any of the signs above, visit your optometrist. They can test you for cataracts, and if you do have them, recommend a treatment option. Cataract surgery is a good choice for many patients, and it is quite safe and easy to recover from since modern varieties use lasers.
