Diabetic retinopathy is another common condition, but usually only occurs in those who have diabetes. Diabetes can damage blood vessels in the eyes over time, causing them to leak blood or fluid, which will, in turn, cause the retina to swell. This will cause blurry vision and must be treated to regain that vision.
Macular degeneration is one of the leading causes of blindness in people. The macula is the retina’s central part that receives images and focuses vision, where the information will then be sent to the brain. Macular degeneration is the deterioration of the central part of the retina vital to clear vision. Dark spots in your vision will begin to appear until blindness sets in. There is no cure for this, but you can protect your eyes by wearing proper prescription-grade sunglasses and indoor glasses to protect your eyes from blue light (such as from phones, TVs, and other electrical devices).
Glaucoma causes fluid buildup in the front part of your eye, which will then put pressure on the optic nerve. In many cases, the optic nerve will be damaged and electrical impulses cannot be sent properly to the brain, resulting in blurry vision or blindness. The good news? Glaucoma can be treated and blindness can be prevented with early treatment. Hypertension is closely tied to glaucoma, as it usually causes glaucoma to set in. Ocular hypertension is when fluid does not properly drain in the front part of the eye, causing that buildup and pressure that will eventually damage the optic nerve.
