4. Tinting of Eyes
Some people notice their eyes changing tint, and that can lead them to get checked by their doctor and find out if they have cataracts. This lens discoloration is one of the most notable signs of cataracts. Unfortunately, you have to be looking in the mirror in order to see it. If you do not look in the mirror very often, or if you do not look closely enough to see that your eyes are changing color, then you are not going to get the benefit of this early warning sign.
Luckily, most people have other people in their lives the look at their eyes often enough where they can tell if there is a change like a lens discoloration. This is different from cloudy vision in that it actually makes your eyes change color slightly. For example, cataracts can cause your eyes to change to a yellowish tint or a brownish tint that appears as different eye color.
