What is "eye"?

The eye is a complex sensory organ that enables vision in humans. It consists of several parts working together to capture and process visual information. The front part of the eye includes the transparent cornea and the colored iris, which controls the amount of light entering the eye through the pupil. Behind the iris is the crystalline lens, which focuses light onto the retina at the back of the eye. The retina contains specialized cells called photoreceptors that convert light into electrical signals, which are then sent to the brain via the optic nerve. The eye also has structures such as the sclera, the white outer layer, and the conjunctiva, a thin membrane covering the front of the eye.

What is a "strain"?

A strain is an injury to a muscle or tendon, often caused by overstretching or overexertion. It can happen during physical activities like lifting heavy objects, exercising, or playing sports. Strains typically result in pain, swelling, and limited movement in the affected muscle or joint. Treatment usually involves rest, ice, compression, and elevation to reduce pain and inflammation. Gentle stretching and strengthening exercises may also help with recovery, along with over-the-counter pain relievers if needed. Severe strains may require medical evaluation and physical therapy for proper healing.

What is "irritation"?

Irritation refers to a condition where a part of the body becomes swollen or sensitive, leading to discomfort or pain. This irritation can occur in various body parts, including the skin, eyes, throat, or internal organs. It is often caused by external factors such as allergens, chemicals, infections, or physical injury. Symptoms of irritation depend on the affected area but can include redness, itching, burning, or soreness. Treatment typically involves avoiding the irritant if possible and using soothing measures like applying cold compresses, taking antihistamines, or using creams to ease symptoms. If the irritation lasts or worsens, medical attention may be necessary to identify and address the underlying cause.

Who is an "optician"?

An optician is a healthcare professional who specializes in providing and fitting eyeglasses and contact lenses based on prescriptions from optometrists or ophthalmologists.

They help clients in selecting frames or lenses that suit their preferences and lifestyle while ensuring proper fit and comfort. They also perform adjustments and repairs to eyewear as needed.
