> **Summary:** Astigmatism glasses are prescribed for blurring at distance, at near or both; they give clear vision but are not a treatment and do not remove astigmatism. Whether they must be worn all the time depends on the degree: below 0.75 they are generally not essential, while from 0.75 upwards they should be worn regularly.

## Quick Facts
- **Low astigmatism (below 0.75):** Glasses generally not needed; the doctor may recommend them if there are complaints.
- **Moderate or high astigmatism (0.75 and above):** Glasses must be worn regularly, with frequent eye examinations.
- **Not wearing glasses:** Does not make the degree progress; vision simply stays uncorrected.
- **Degree range:** Generally between 0.25 and 6.00 dioptres (D).

## Do Astigmatism Glasses Need to Be Worn All the Time?
- Glasses make objects clearer but do not treat or remove astigmatism.
- Not wearing them does not raise the degree of astigmatism.
- Below 0.75: glasses are generally not needed and the doctor may recommend them if there are complaints, but routine check-ups must still be attended.
- 0.75 and above (moderate or high): glasses must be worn regularly and eye examinations carried out frequently.

## What Causes Astigmatism?
It arises when the curvature of the cornea or lens is not perfectly round. In most people it is linked to a genetic predisposition; a family history raises the risk. Causes listed:
- Genetic factors
- Pressure on the cornea from the eyelids
- Eye surgery and complications arising during it
- Eye injuries
- Keratoconus

## Symptoms
- Unclear vision at distance and near
- Headache, eye pain and more frequent dizziness
- Tiredness and pain around the eyes despite rest
- Squinting to focus
- Worse night vision
- Watering eyes

## Degrees of Astigmatism
- **Low (below 0.75):** Mild, beginning stage. Vision problems are rare, so glasses or lenses are generally not needed; the doctor may recommend them if there are complaints. Regular check-ups are still needed.
- **Moderate (0.75 to 2.00):** The most common group. Distance, near or both can become noticeably less clear, with possible headache and eye strain. Doctors recommend glasses or toric contact lenses.
- **High (above 2.00):** Vision seriously impaired, objects look distorted and wavy, and daily activities get harder without treatment. Refractive surgery such as LASIK can be used alongside glasses or lenses; check-ups as often as the doctor recommends.

## Effects on Daily Life
- Blurred, distorted, shadowed or double vision while driving
- Eye tiredness and straining to focus
- Recurring headaches from eye strain
- Considerable difficulty with night vision
- Difficulty concentrating on reading, a phone, study or work
- Squinting without realising it
- In severe astigmatism, affected depth perception, which can cause loss of balance on stairs or in busy surroundings

## Diagnosis and Treatment
Diagnosis starts with symptoms (vision problems, headache, eye pain) and is confirmed with:
- Keratometry
- Refraction test
- Visual acuity test

Treatment depends on the degree. Glasses and contact lenses are the first choice. Where the degree is high, laser treatment is also recommended (iLASIK, No Touch Laser or PRK). Other methods:
- Phakic intraocular lens surgery
- Intraocular lenses
- Toric trifocal intraocular lenses

## Frequently Asked Questions

**Q: Is it essential to wear astigmatism glasses all the time?**
A: Some people with mild astigmatism can manage without glasses during the day. Regular wear is more comfortable while driving, during long screen work, or when there is headache and eye strain. An eye examination determines the right plan.

**Q: Will my astigmatism get worse if I do not wear glasses?**
A: Generally the degree does not increase directly, although blurred vision, eye strain and headache can continue. If the degree does change, a check-up is needed to look into the causes.

**Q: What are the most common symptoms?**
A: Blurring at distance or near, shadowed or double vision, eye strain, headache and difficulty with night vision. Persistent complaints call for an examination.

**Q: Does astigmatism progress?**
A: Measurements can change over time and can increase, particularly in conditions such as keratoconus, so regular examination matters.

**Q: Are contact lenses or glasses better?**
A: Both can correct astigmatism. Glasses are practical and safe; toric contact lenses can give a wider field of vision in some people. Suitability depends on eye structure and lifestyle.

**Q: Can laser correct astigmatism completely?**
A: In some patients laser can reduce or correct it, but not everyone is suitable. Corneal structure, prescription stability and dry eye are assessed; other options can be considered where laser is not suitable.
