A number of professionals using computers experience vision and eye-related problems especially due to poorly designed work stations and prolonged usage. These vision-related problems are grouped as Computer Vision syndrome in short “CVS”.
The primary symptoms are :
Computer Vision Syndrome ( CVS ) affects 75% of computer users, most markedly those who work more than 3 to 4 hours with computers. Computer users? productivity is affected.
Uncorrected refractive error
Decreased blink rate
Glare and reflection from the monitor
Poor Ergonomics
Evaluate at simulated computer environment ( Questionnaire + Executive Vision check + Orthoptics + Tear function )
Management
Glass
Artificial tears
Vision therapy
Recommendations about ergonomics
Cataract is the clouding of the eye’s lens leading to blurred vision and blindness.
Cloudy or blurry vision.
Problems with light, such as headlights that seem too bright, glare from lamps, or very bright sunlight.
Colors that seem faded.
Poor night vision.
Frequent changes in glasses or contact lenses.
People over 60 years, Infants with congenital cataracts due to mother having infectious diseases during pregnancy.
Cataracts are removed through surgery which lasts about 10-20 minutes. The natural lens is removed under local anaesthesia and replaced with an intraocular lens.
The surgery has an over 98% success record resulting in better vision.
The cost depends upon the lens used. It varies between Rs. 20,000/- and Rs. 50,000/- per eye.
The fluid within the eye called the aqueous humor usually exerts a pressure between 12 to 18 millimetres of mercury. The abnormal rise of this pressure is called Glaucoma. This pressure damages the nerve fibres and causes irreparable damage resulting in gradual loss of vision leading to blindness. Can Glaucoma be cured? No. It can only be controlled. The lost vision can not be regained.
Are over 40 years of age
Have a family history of glaucoma
Diabetic
Abnormally high IOP
Nearsighted
Regular, long-term use of steroids/cortisone
Previous Eye injury
IOP can be measured using a tonometer which could be used in the diagnosis and treatment of glaucoma.
Causes of high IOP: The clogging of the paths and chambers in the eye which traps the aqueous humor results in a pressure buildup leading to high IOP.
Glaucoma is a chronic disease and requires constant medication to lower the IOP levels. Surgical procedures are used if the medication is unsuccessful.
When the cornea is damaged beyond repair it is removed either fully or partly and replaced by a donated cornea.
The cornea is the clear outer layer covering the eye. It helps focus and transmit light as it passes through the lens onto to retina.
Anyone with no infectious diseases.
Do not rub or touch the eye.
Avoid smoky and dusty rooms, which can cause irritation.
You will need at least 2-4 weeks off work, but again this will be discussed with you on an individual basis.
Avoid driving until the doctor tells you otherwise.
Consult your doctor in case of increased pain, redness, watering or discharge or reduction of vision
Yes. Some of the diseases it causes are diabetic retinopathy, glaucoma, cataract, infections, and refractive errors.
No symptoms at the early stage. An increase in floaters and even a mild reduction in vision should be evaluated in diabetic patients.
When the retina is pulled or lifted from its normal position it results in a detachment. This causes permanent vision loss if not treated immediately. This is a medical emergency and should be treated immediately.
Sudden or gradual increase in floaters
Flashes of light
Appearance of a curtain over the field of vision
Who is at risk of retinal detachment?
It can occur at any age but people over 40 are at a higher risk.
Men are more prone to it than women.
People who are extremely nearsighted.
People with a family history of retinal detachment.
People with other eye diseases or injuries.
