Astigmatism is a typical vision problem that occurs when the shape of the cornea is distorted due to injuries or other causes. With astigmatism, the lenses of the eye or the cornea curves. This irregular curve can change the way light refracts or passes through your retina. This causes hazy, fluffy, or twisted vision. Farsightedness and partial blindness are two different sorts of issues with the way light goes to your retina. Farsightedness is called hyperopia. Partial blindness is called astigmatism.
Types: There are two types of Astigmatisms. These are:
- Corneal astigmatism: It happens when your cornea itself is distorted.
- Lenticular astigmatism: Lenticular astigmatism happens when your lens is distorted.
Risks: Astigmatism can happen in youngsters and grown-ups. Your danger of creating astigmatism might be higher if you have any of the following:
- A family history of astigmatism or other eye issues like dislocation of the cornea.
- Scarring or diminishing of your cornea
- Excessive partial blindness, which makes foggy vision at a separation
- Excessive farsightedness, which makes hazy close-up vision
- A past of eye surgeries, for example, cataract surgery (surgical expulsion of a blurred focal point)
Symptoms: The side effects of astigmatism include:
- Hazy, Bended, Or Fluffy Vision At All Separations (Close-Up And Far Away)
- Trouble seeing during evening
- Lazy eye
- Irritation in the eye
- Cerebral Pains
- Visual Acuity Assessment Test: Patients are required to read letters from a graph at a particular distance to decide how well they can see the letters.
- Refraction Test: A refraction test uses a machine called an optical refractor. The machine has various remedial glass lenses that are used to read an outline while looking through lenses on the optical refractor.
- Keratometry: Keratometry is a route for your specialist to measure the bend of your cornea. They will do this by taking a look at your eye through a keratometer.
- Corrective Lenses: Remedial eyeglasses and contact lenses prescribed by a specialist are the most well-known and least obtrusive solution for astigmatism.
- Orthokeratology: Orthokeratology is a treatment that uses contact lenses to correct the deformation and flow of your cornea. You will wear inflexible contact lenses for certain time-periods. It is easier to wear them while you are sleeping and remove them during the day.
Surgery: Your specialist may suggest refractive surgery if your case is a serious one. This kind of surgery includes use of lasers or little blades to reshape your cornea. This will correct astigmatism permanently. The three basic surgeries for astigmatism are:
- Laser in situ keratomileusis (LASIK)
- Photorefractive keratectomy (PRK)
- Spiral keratotomy (RK).
All these surgeries might carry some risks depending upon the symptoms of your problem. As innovation advances, it is very important for the patient to explore more options before choosing which refractive surgery is a good fit for him or her. If you wish to discuss about any specific problem, you can consult a ophthalmologist.

Did you know that your vision is responsible for around 80% of you sensory input? your eyes are among the most delicate organs in your body. Long work hours in front of the computer and long study hours results in tired and sometimes irritating eye conditions. But help isn't too far. Before you head to the doctor, you can head to your kitchen to look for solutions. There are several home remedies that you can try to not only improve your eyesight but also get rid of glasses and rebuild your vision! here's how you can do it:
1. Exercise: Just like any other body part, your eyes need exercise too. Blinking your eyes rapidly for 5 seconds helps moisturize it. Similarly, cupping your eyes with you palms for 4-5 minutes triggers acupuncture points that helps the eye to relax. There are specific exercises to reduce eye strain, improve blurred vision and enhance reading. Do these as per the specific problem you are facing.
2. Take a break: Follow the 10-10-10 rule when you are on the computer for extended hours. For every half hour of work, take a 10 min break to look at something n a distance at least 10 feet away for 10 seconds. These becomes tricky if you are studying or working in a fast paced environment and easily forget to take breaks. Set alarms that help you know the time so that you can actively plan your breaks. To enhance break time, try to look at greenery during your 10 sec break which helps the eyes relax better. Splash your eyes with cold water to give them a fresh feel.
3. Yoga: Yoga and meditation relaxes your body and mind. It is also a great way to relax your eyes as you get to close them and give them rest. When you close your eyes, you shut out a big chunk of sensory inputs helping your body go from an active reaction mode to a passive action mode.
4. Eat for your eyes: Make sure you add your weekly quota of vision enhancing food in you diet. Carrots which are rich in beta-carotene and vitamin a are great for the eyes. Similarly grapes and blueberries work great to improve your night vision. Green leafy veggies, garlic, shallots, eggs and onion all contribute in keeping your eyes healthy and strong. Cold water fish rich in DHA is an another great food that helps reduce dry eyes and muscular degeneration.
5. Change your lifestyle: Other than exercise and proper nutrients, you need to ensure you get a shut eye for six to eight hours every day to let your eyes fully rest and rejuvenate. As always drink 6 - 8 glasses of water. And don't forget to get regular eye check ups especially if you are a diabetic or have other health conditions that adversely affect your eyes.
After my sleep my eyes are becoming very red in colour and I had a peculiar skin writing problem i. E when I am scratching the skin becomes very red and swollen. Please give me immediate remedy.
Vision is one of our most important senses. Reduced vision that triggers the need for corrective glasses is one of the most common disorders associated with the eyes. Crossed eyes are another such common disorder that affects the eyes. In medical terms it is also known as Strabismus. This condition is a result of miscommunication between the brain and the eye muscles that result in misalignment of the eyes. It is largely a hereditary condition and should not be confused with a lazy eye syndrome.
Crossed eyes can cause double vision and disorientation. Your depth perception may also be affected. It also causes eye strains and headaches that affect the quality of your life. This condition is seen mostly in children. If not treated in time, it can continue into the adult years as well. The development of crossed eyes in adults who have not suffered from this condition as children is usually a sign of a serious condition such as a stroke.
Some symptoms characteristic of this condition are:
- Independent movement of eye balls
- Tilting the head to a side
- Varied points of reflection in each eye
- Frequently bumping into things as a result of impaired depth perception.
Treatment for this condition can be surgical as well as non surgical. Non surgical treatment aims at strengthening the eye muscles and treating the visual system as a whole. The aim is to not allow the eye to become lazy or amblyopic. Wearing an eye patch over the strong eye and forcing the weak eye to be used is one of the most common form of this treatment. Corrective glasses can also be used to treat this condition in cases where it has been triggered by excessive farsightedness. In some cases, medication may also be injected into the eye to relax the eye muscles.
Surgery to correct this disorder involves correcting vision by strengthening or weakening the eye muscles. To do this, a surgeon must first make a small incision in the outer layer of the eyeball to reach the affected muscles. To strengthen the muscle a small section is removed from the muscle and the remaining part is then rejoined. This makes the muscle shorter and forces the eye to turn towards that side. Alternatively, the doctor may make a partial cut across the muscle to elongate it and let the eye turn further away from it.
