There could be several types of vision problems associated with eyes. It can either occur from a disorder in the eye and its parts or could be a side effect of complications in nervous system or side effect of medicines.


Common types of vision problems in the eyes

Refractive errors

Myopia (nearsightedness) is a condition wherein nearby objects appear clear but distant objects look blurry. It happens because light gets focussed before the retina instead of on the retina.

Hyperopia (farsightedness) is a condition wherein distant objects appear clear and nearby objects look blurry. It happens because light gets focussed behind the retina instead of on the retina.

Astigmatism occurs due to irregular shape of the cornea. The light gets focussed unevenly other than on the retina which leads to blurred vision.

Presbyopia is natural part of the aging process and it happens due to hardening of the lens. The light rays are not focussed properly and problems occur due in close vision.

Strabismus (crossed eyes)It’s a condition in which both eyes do not look at the same place at the same time and occurs due to poor eye muscle control. The eyes could turn inward, outward, downward or upward

Amblyopia (lazy eyes) results from improper co-ordination between the brain and the eyes. The vision in one eye may be normal but the other eye might be highly farsighted. Misalignment is eyes can also cause lazy eyes.

Diabetic retinopathy: It’s a serious complication of the eye that starts with blurry vision then progresses to complete loss of vision.  Diabetic retinopathy can also lead to blindness. It happens due to abnormal swelling and leakage in the blood vessels of the retina.

Glaucoma: The optic nerves of eyes are damaged and pressure often builds up inside the eyes. Problems in vision definitely arise and if eye pressure is not managed, the patient might suffer from permanent loss of vision.

Cataract: It’s an eye disease that occurs when the lens loses its transparency. The lens become opaque and cloudy due to which vision is diminished. Cataracts are more common in older age group people

Age Related Macular Degeneration: ARMD usually shows up in people above age 50 and it characterized by gradual loss of central vision which is responsible of detailed vision of the eye.  


Other problems in eyes that leads to vision problems
  • Diabetes, stroke, brain injury, arterial damage of the brain, migraine headaches
  • Infections in the cornea, retina, optic nerve, uvea, and iris
  • Presence of foreign objects in eyes


How does the vision change?

Apart from having trouble in focusing near or distant objects, vision change is experienced as: 

  • Seeing halos
  • Seeing dark spots around
  • Blurriness in vision, double vision, overlapping vision, stretching of images
  • Twitching of eyes, eye strain, headache
  • Redness and swelling of eyes


What should you do if you are having vision problems?

Doctors advise eye check-up as a part of routine medical diagnosis as well, even if your vision is normal

Otherwise, you need to immediately see an eye specialist if you are experiencing vision problems. 

You eyes will be thoroughly checked with various diagnostic techniques to figure out the exact problem. Problems in nervous system would also need clinical diagnosis.


What are the treatment options for vision problems?

The treatment depends on the underlying problem.

Some options are: 

  • Corrective lenses, glasses, prisms, etc. for refractive errors.
  • Surgery for eye disorders like cataracts. Laser surgery may also be recommended for refractive errors.
  • Antibiotic eye drops for curing infections 

Never delay for an eye check up on experiencing vision problems. Your eyes are precious, so take care!
