When your eyes feel like this, it's time to act – 6 signs your eyesight is threatening

There are certain eye symptoms that require a visit to a health center or directly to an ophthalmologist.

1. Vision worsens

If your eyesight seems to be getting progressively worse, it may be time to get or upgrade your glasses.

However, eye disease can be behind visual impairment.

The most common eye diseases that slowly affect vision are glaucoma, diabetic eye disease, or age-related macular degeneration.

Sudden deterioration of vision can be due to eye infection, blocked blood vessel in the eye, retinal detachment and acute glaucoma attack.

Common diseases can also affect vision. For example, a cerebrovascular disorder can cause sudden vision loss. If you have vision problems with neurological symptoms such as speech disorders or stroke symptoms, you should seek treatment immediately.

For example, MS and brain tumors can also cause visual symptoms.

2. Lightning in the eyes

Glare, i.e. bright flashes at the edges of the visual field, is usually a sign of the onset of vitreous detachment.

Simple detachment of the vitreous causing moving opacities such as lightning and gauze is often harmless. Because of them, if no other changes in vision appear, it is not necessary to see an ophthalmologist immediately. A general practitioner can also check the situation.

If lightning lasts for a long time and a dark uniform shadow appears in the field of vision, rain of soot, distortion of lines or deterioration of vision, detailed examinations by an ophthalmologist are urgently needed. Symptoms may indicate retinal detachment, which can be vision-threatening. Treatment is often eye surgery.

3. The eye is dim, but there is no pain

Partial or complete blurring of one eye over a few hours or days may indicate vitreous hemorrhage or retinal vein occlusion. In this case, there is no pain associated with fading.

See an eye doctor in the next few days.

If vision suddenly worsens in the other eye, seek immediate treatment. It could be retinal artery occlusion.

4. Blurred vision, eye pain

Sudden blurred vision, severe headache, nausea and eye pain may indicate a sudden attack of intraocular pressure.

In this case, the pupil of the painful eye is often enlarged.

You should see a doctor immediately.

This should be done even if there are symptoms related to inflammation of the temporal artery: blurred vision in one eye, pain in the temple, decreased general condition and pain in the jaw when chewing.

5. Vision is dim and lights are dazzling

If the vision in one eye is blurred, at the same time sensitive to light and the white part of the eye is intensely red, it may be inflammation of the iris, i.e. iritis.

The pupil of the painful eye may also be smaller than normal.

The matter will be investigated in the coming days.

6. Everything appears as two

Double images always indicate disease. Sudden onset of double vision may be due to severe brain dysfunction. In this case, you should seek treatment immediately.

Tumors, hemorrhage, or swelling in the head can also cause double vision.
