– When symptoms appear: Vision changes such as the appearance of floaters, blurry vision, double vision, or the reduced ability to focus on an object can indicate problems affecting the eyes whether the actual cause is in the eye itself or another underlying condition. When these happen, the person may approach an eye specialist for a consultation.
– If a person is predisposed to possible eye problems: Some eye conditions are hereditary. These include cataracts and retinal degeneration that can start during infancy. In some cases, they don’t manifest until the person is older. A good example is glaucoma, which causes irreparable damage to the nerves of the eyes as the pressure of fluid builds up. Since the nerves are damaged, the person experiences a permanent decrease of vision. This is often hereditary, but the symptoms don’t appear unless the person starts having vision problems. Further, it may take ten years before the symptoms manifest. As such, only regular eye consultations can identify or monitor its development. Certain preexisting diseases can also increase the risk of developing eye problems. These include diabetes, which can lead to diabetic retinopathy or nerve damage to the eyes.
