Does the paper on this label shrink suddenly? If you are 40 or older, you may ask yourself a question because it is difficult for you to read content that you could see without problems before.

Blame your old eyes. Just like our joints, our eyes experience age-related changes. Although eye problems may affect people of any age, certain conditions become more common after the age of 40.

Getting old?Three common eye diseases

Presbyopia. As you get older, the lens of your eye becomes harder and harder, which makes it more difficult to focus on nearby objects-therefore, your label reading job gets stuck. Many people are satisfied with cheap reading glasses, but once you need them, it’s time for a middle-aged vision check.

cataract. Cataract is another common condition that appears with age. Cataract can damage vision. Cataracts affect about half of people between the ages of 65 and 74. Treatment usually includes outpatient surgery to replace the cloudy lens.

Dry eye syndrome. In the United States, the disease affects more than 15 million adults and occurs due to a decrease in tear production. With less natural lubricant, your eyes may become irritated and sticky, or you may feel a burning or scratching sensation in your eyes. Depending on the severity, eye drops that mimic your natural tears, topical medications, or devices that increase tear production can be used to treat symptoms.

Other eye diseases that may be caused by age or disease

Post vitreous detachment (PVD). Signs of this condition include visual disturbances, such as seeing pinstripes, floating objects, or smog like spider webs. This happens because the jelly-like substance called the vitreous in the eye begins to liquefy and contract, causing it to pull onto the retina.

If you find these signs, call your medical team immediately. Although most people who experience PVD do not need treatment, in some cases, the vitreous body may completely detach or tear the retina. According to the American Association of Retinal Specialists, tears or detachments may cause vision loss and require laser surgery or surgery to repair the problem.

glaucoma. Another condition that becomes more common after the age of 40 is glaucoma. This painless and usually asymptomatic condition damages the optic nerve, which transmits information from the eye to the brain. If left untreated, glaucoma can cause loss of peripheral or central vision. The most common treatment for glaucoma is the use of prescription eye drops, which are designed to relieve pressure on the eyes. Less commonly, your doctor may recommend laser surgery or surgery.

Age-related macular degeneration (AMD). This condition can cause retinal degeneration, which is a thin layer of tissue at the back of the eye. The light-sensitive cells of the retina capture the image and transmit it to the brain through the optic nerve. AMD affects the central part of the retina called the macula. It may cause blurred or distorted vision, and may cause blind spots in a person’s field of vision. Treatment (which may include medication or laser treatment) can often help prevent or at least delay vision loss.

Diabetic retinopathy. This condition can also cause damage to the retina. For diabetics, controlling blood sugar and blood pressure helps prevent diabetic retinopathy. If it is detected, your ophthalmologist will recommend treatment, usually eye injection or laser treatment.

An easy way to keep your eyes healthy

If many eye diseases are detected early, they can be effectively treated to protect your eyesight. This is why it is wise to have regular eye exams to find potential problems and fix them before they affect your vision.

You can also take other steps to keep your eyes healthy, such as exercising, eating a healthy diet, quitting smoking, and protecting your eyes from UV rays by wearing sunglasses outdoors.
