Eye care professionals are very much in demand today. The use of computers, tablets and mobile phones for long hours has resulted in vision problems for a large number of people. About 285 million people all over the world are visually impaired of which 246 million have low vision, according to research by WHO.

It is a good idea to see an eye care professional for regular eye examinations to ensure perfect vision after the age of 35 or 40.Finding a good eye care professional requires some knowledge about this line of work. An optometrist provides general eye care while ophthalmologists provide eye surgery, in addition to eye care. Currently, in most locations, optometrists prescribe eyeglasses and contact lenses. Some optometrists also provide low vision care and vision therapy. Opticians use prescriptions written by an optometrist or an ophthalmologist to fit and sell eye-wear. Opticians are usually not licensed to diagnose or treat eye diseases.

You need to consult an eye care professional in the following cases:

• Pain in the eye
• Unusual red eye
• Dryness of eyes
• Bulging of eyes
• Eyelid irregularities
• Dark curtain or veil that blocks vision
• Diabetes mellitus
• Double, decreased or distorted vision
• Seeing halos (colored circles around lights)
• Loss of peripheral (side) vision
• Eye injuries

Certain eye disorders and vision conditions are developing at a much younger age. Some serious eye diseases like glaucoma, macular degeneration or diabetic retinopathy would require regular monitoring and treatment by eye care professionals.

Ageing may naturally cause a deterioration of vision. Many individuals over 40 lose the ability to focus on things that are near (presbyopia) and see clearly in low light. A qualified eye care professional can help with the correct prescription eye glasses or lenses according to your needs and lifestyle. Detecting and treating problems early can help maintain good eyesight throughout your life.
