old flower
With age, the elasticity of the eye lens decreases, the ability of the eye to adjust gradually weakens, and it begins to feel blurry when seeing close objects.
Common symptoms:
Fatigue or lack of clarity when working in close proximity
Unconsciously taking the book/mobile phone away
Likes to read in a well-lit environment
Presbyopia is an inevitable stage in life, and you can see objects at close range with only the right presbyopia/progressive glasses.
glaucoma
Glaucoma is one of the most common blinding diseases. When the pressure in the eyeball is too high and exceeds the limit that the optic nerve can bear, it will cause damage to the optic nerve and affect the visual function.
The symptoms of early glaucoma are difficult to detect. Therefore, it should be checked regularly by an optometrist, such as intraocular pressure examination and fundus examination. If glaucoma is found, it can be treated early to preserve the remaining vision.
diabetes upper eye
The fundus of the eye is full of large and small blood vessels, and unhealthy blood in diabetic patients affects the function of the blood vessels in the fundus. Fundus will appear leakage, abnormal microvascular, bleeding, edema, etc., affecting vision.
Diabetic patients should control their blood sugar well and check their eyes regularly. If diabetic upper eye is found, they should receive treatment as soon as possible, such as injection of fundus vascular endothelial growth factor inhibitor.
cataract
The lens of the eye deteriorates and becomes opaque, preventing the image from being sharply focused on the retina. Like a camera lens with dirt.
Early cataracts can be regularly observed by an optometrist, and surgery can be considered when the cataract affects vision.
UV protection, such as wearing sunglasses during the day, can slow the development of cataracts.
Elderly yellow class disease
The retina degenerates with age, and granular deposits remain in the macular, which in severe cases can lead to yellow spot hemorrhage and fluid leakage.
Symptoms include blurred central vision, image distortion, and a blind spot in the center of the image.
There is no treatment for the early yellow class disease, and patients can adjust their living habits (quit smoking, eat more green vegetables, and take antioxidant supplements) to delay the disease.
