ARK(자동굴절계) 검사 결과 값 이해하기

  안과 검진에서 흔히 접하게 되는 **ARK(자동굴절계, Auto Refractor Keratometer)**는 안구의 굴절 상태를 빠르고 정확하게 측정해주는 장비입니다. 이 기기는 근시, 원시, 난시와 같은 굴절 이상뿐 아니라 각막 곡률 정보를 제공하여 안경, 콘택트렌즈 처방이나 안과 질환 진단에 중요한 자료를 제공합니다. 이번 포스팅에서는  ARK 검사 결과 값이 의미하는 것 과 이를 통해 확인할 수 있는 정보를 상세히 설명하겠습니다. ARK(자동굴절계) 검사 결과 값 1. ARK 결과 값 주요 항목 (1)  Sphere (SPH, 구면값) 의미 : 근시(-) 또는 원시(+)의 정도를 나타냅니다. 표기 방식 : 숫자 값 뒤에 음수(-)나 양수(+)가 표시됩니다. 근시(-) : 초점이 망막 앞쪽에 맺힘 → 멀리 있는 물체가 흐릿함. 원시(+) : 초점이 망막 뒤쪽에 맺힘 → 가까운 물체가 흐릿함. 단위 : 디옵터(D, Diopter). (2)  Cylinder (CYL, 난시값) 의미 : 난시의 정도를 나타내며, 눈의 굴절력이 각 방향에서 일정하지 않을 때 표시됩니다. 표기 방식 : 숫자 값 뒤에 음수(-) 또는 양수(+)가 표시됩니다. 난시의 정도가 클수록 값이 커짐. 단위 : 디옵터(D). (3)  Axis (AXIS, 난시축) 의미 : 난시가 발생한 각도를 나타냅니다. 표기 방식 : 0°부터 180° 사이의 숫자로 나타내며, 난시의 방향을 결정합니다. 예: 90° → 수직 난시, 180° → 수평 난시. (4)  Pupil Distance (PD, 동공 거리) 의미 : 두 눈의 동공 중심 간 거리(mm)를 나타냅니다. 용도 : 안경 렌즈의 중심을 정확히 맞추기 위해 필수적인 데이터입니다. (5)  Keratometry (각막 곡률값) 의미 : 각막의 곡률 반경을 측정하여 각막의 굴절력을 나타냅니다. 결과 값 : K1 (평평한 곡률): 각막의 가장 완만한 곡률 값. K2 (가파른 곡률): 각막...

Eye Allergies: Causes and Solutions

 

What Are Eye Allergies?

Eye allergies, also known as allergic conjunctivitis, occur when the eyes react to allergens in the environment. This condition leads to redness, itching, swelling, and excessive tearing. Unlike infections, allergic conjunctivitis is not contagious but can be chronic and disruptive to daily life.

Causes of Eye Allergies

Eye allergies are triggered by the immune system’s overreaction to certain substances. Common causes include:

  • Pollen: Seasonal allergies (hay fever) are often caused by pollen from trees, grass, and weeds.

  • Dust Mites: These microscopic organisms are common in household dust and bedding.

  • Pet Dander: Proteins found in pet skin flakes, saliva, and fur can cause allergic reactions.

  • Mold: Mold spores in damp environments can lead to allergic symptoms.

  • Smoke and Air Pollution: Smoke, strong odors, and airborne pollutants can irritate sensitive eyes.

  • Contact Lenses: Some people develop allergies to lens materials or cleaning solutions.

  • Cosmetics and Eye Drops: Certain makeup products and preservatives in eye drops may trigger allergic reactions.

Symptoms of Eye Allergies

Common symptoms include:

  • Red, itchy, and watery eyes

  • Swollen eyelids

  • Sensitivity to light

  • Burning sensation

  • Blurred vision (in severe cases)

Solutions and Treatment for Eye Allergies

Managing eye allergies requires a combination of prevention and treatment. Here are some effective solutions:

1. Avoid Allergens

  • Check pollen forecasts and stay indoors during peak allergy seasons.

  • Use air purifiers and keep windows closed to reduce allergens indoors.

  • Regularly wash bedding, curtains, and upholstery to remove dust mites.

  • Keep pets out of bedrooms and groom them regularly.

2. Over-the-Counter (OTC) Medications

  • Antihistamine Eye Drops: Help reduce itching and redness.

  • Artificial Tears: Flush out allergens and provide relief.

  • Decongestant Drops: Reduce eye redness but should be used sparingly.

3. Prescription Treatments

  • Mast Cell Stabilizers: Prevent allergic reactions before they start.

  • Steroid Eye Drops: Used for severe allergic reactions but require a doctor’s supervision.

  • Oral Antihistamines: Help control overall allergic responses.

4. Lifestyle Adjustments

  • Wash hands frequently and avoid rubbing your eyes.

  • Wear sunglasses to protect against airborne allergens.

  • Use hypoallergenic makeup and replace old cosmetics regularly.

When to See a Doctor

If symptoms persist despite treatment, or if vision problems develop, consult an eye specialist to rule out infections or other serious conditions.

Conclusion

Eye allergies can be frustrating, but proper management can significantly reduce symptoms. By identifying triggers, using the right treatments, and making small lifestyle changes, individuals can maintain better eye health and comfort.
