We are able to contact the environment through our sense organs. Our five sense organs eyes, nose, ears, tongue and skin help to protect our body. They contain receptors which relay the information through sensory neurons to the brain.
Sight is one of the most important senses which are possible through our eyes. Eyes are complex organs that have many parts which must act together to create a clear vision. However, eye problems can occur due to injuries, infections or age. There are several eye problems. Some are minor, but some can result in permanent loss of vision.
What Are the Common Eye Problems?
Common eye problems include:
- Refractive Errors: These are vision problems which occur when the shape of the eye prevents the light from focusing directly on the retina.
- Macular Degeneration: This disease destroys the sharp, central vision.
- Cataracts: It is the condition of clouding of the lens in your eye.
- Diabetic Eye Problems: The most common diabetic eye problem is diabetic retinopathy, which is a primary cause of blindness in American adult.
- Optic Nerve Disorders: These disorders include glaucoma.
- Conjunctivitis: It is the inflammation of conjunctiva.
- Retinal Disorders: These diseases can affect any part of your retina. They include a retinal tear, diabetic retinopathy and retinitis
pigmentosa and several other disorders.
Regular eye checkups are the best defence against eye diseases. Early detection and treatment can help to prevent vision loss. Seek the help of an eye care professional right away if observe symptoms as a sudden change in vision, pain, inflammation, double vision or fluid coming from the eye.
How Omega-3 Is Beneficial for Eye Health?
According to the American Optometric Association (AOA), dietary deficiency of DHA leads to retinal degradation or visual impairment, and dry eye syndrome is associated with the deficiency of omega-3. Various studies reveal that omega-3s play a significant role in the eye health as:
- DHA (Docosahexaenoic acid) is naturally concentrated in the retina of the eye promotes the healthy retinal function. The retina uses DHA to redevelop the outer section of the photoreceptors of the eye to process light. It also uses DHA to defend retinal pigment cells from damage.
- Results of several studies show that consuming larger amounts of omega-3 or fish can help to promote macular health (macula is the centre of the retina). It is shown that omega-3s may be helpful in reducing the risk of macular degeneration. Macular degeneration is one of the main causes of blindness globally. Also, omega-3s can be helpful to decrease dry eye syndrome (a chronic eye disorder caused by a reduction in the production of tear or elevation in the tear evaporation).
- Studies reveal that omega-3 rich diet decreases the harmful new blood vessel development that in some cases occurs in severe types of diabetic retinopathy.
- Omega-3s can help in adjusting the microcirculation of blood flow in the optic nerve and eye. Studies reveal that patients with glaucoma are likely to have low blood levels of EHA and DHA.
