If you are a diabetic, you may worry about the adverse effects that this chronic disease may have on your sight. Because of disease increases your risk for eye problems, make sure you do not ignore the following three early warning signs of glaucoma.

1.  Strange Auras When Looking at Lights

One of the first symptoms that may alert you to a possible problem with your vision is the presence of strange auras while you are looking at lights. You may see a soft halo while looking at a light bulb, or you could see small rainbows arching around the light source.

Glaucoma causes pressure to build up within your eyeballs. As a result, the shape of the cornea can change slightly, causing light to refract in unusual ways, resulting in the auras you are seeing.

2.  Changes in the Eyes' Appearance

The pressure within the eyes not only affects the way you see light. It can also change the way your eyes look.

When you have glaucoma, a strain is placed on the tiny blood vessels of your eyes. This strain can then cause microbursting of the capillaries, making your eyes appear bloodshot.

Around the broken capillaries, the whites also change in appearance. Instead of being a clear white color, you may notice that they start looking milky or take on a slightly yellowish hue. However, the latter could also be a sign of liver problems, so you should see your doctor immediately so they can determine what is causing the change in the color.

3.  Dull Ache or Pressure in the Eyes

Another early symptoms of glaucoma you may notice and should not dismiss is a dull ache in your eyes. This discomfort may also present itself as a pressure sensation that resembles sinus pain, although you may not have any other sinus symptoms.

While this achy pressure is constantly present with glaucoma, the sensation becomes worse when you strain your eyes by overusing them, such as you do while looking at a computer screen for hours or reading small print. However, if you start having sharp pains, contact your doctor immediately, as this could be a sign of acute glaucoma.

If you start experiencing one or more the symptoms above, you may be in the early stages of glaucoma. If you suspect that this is the case, visit your physician or eye doctor to have them diagnose you and discuss with you any available eye disease treatment options.
