Doctors say that everyone should get their eyes checked at least once a year, especially after the age of 40. Many diseases can be easily cured if detected early, but for that, an eye check-up is necessary.

When a sick person goes to the doctor, the doctor checks the eyes along with the tongue pulse. Have you ever wondered what the doctor checks in the eyes, what does the doctor see when he looks into your eyes, can the disease be seen in the eyes? Actually, when the doctor looks at your eyes, he can know many things related to your health. Symptoms of many diseases of the body are also visible in the eyes.

Dr. Charles P. Wilkinson, a retina specialist at the American Academy of Ophthalmology, says that looking at the eyes from inside is really a wonderful experience. This is the only place where we can see the blood vessels running directly. Even the optic nerve, a part of the brain, is visible. In

A research ( .), VSP Vision Care Company looked at the data of 1.2 lakh patients and found that 34% people got to know about diabetes for the first time through eye examination, 39% got to know about high blood pressure through eyes and 62% got the first sign of high cholesterol through eyes. Let us know 9 such signs which the eyes give and which can point towards major diseases.

Red spots or blood drops in the eyes

This can be a sign of diabetes. When the sugar level in the body increases a lot, the small veins of the eyes burst and bleeds. If this condition is not corrected on time, it can also lead to blindness.

Red eyes, itchy and swollen red eyes

Red eyes can be caused by a variety of things – including a lot of coughing, pink eye (conjunctivitis), or a fungal infection. Inflammation and itching are often a sign of allergies – such as to dust, pollen or pet dander. In this case, eye drops can help, especially if they contain an antihistamine.

Dryness of the eyes

Excessive use of laptop/mobile, sleeping pills or anxiety medicines can cause dry eyes. Some autoimmune diseases can also cause this, such as Sjogren's syndrome, which occurs especially in older women.

Blurred vision and inability to see near objects clearly

This is common with ageing but some medicines like antihistamines, diuretics or antidepressants can cause this problem prematurely. This is called Presbyopia. Apart from this, if you already have a problem of high blood pressure and suddenly start seeing blurry, then you should immediately consult a doctor. This can be a sign of retinal detachment or the effect of high blood pressure.

Sudden flashes of light or spots before your eyes, white rings or yellow spots on your eyelids

This can also be a symptom of retinal detachment. If along with this, you lose your side vision, then it could be a case of retinal detachment – immediate treatment is needed. White rings around the eyes or yellow spots on the eyelids can be a sign of high cholesterol. These rings are more visible especially in older people. But if this happens, then a blood test should definitely be done.

Some cancers can also be detected through the eyes

Ocular melanoma is usually not visible in the mirror. If no other reason is found for pain or pressure in the eyes, then the doctor also checks for brain tumor. Doctors advise to get your eyes checked from time to time because eyes are not just a means of seeing, they are also an indicator of health.
