Further, more and more people are buying inexpensive glasses with low-quality lenses which also adversely affect the eyes. These types of glasses might affect the quality of vision of the eyes rather than protecting it, creating long-lasting effects.[break]
The increment in infections is understandable, as dust particles have increased due to dryness, unmanaged urbanization and traffic problems.
Springtime, which looks spectacularly pretty, is actually hard on the eyes, explains Dr Mohan Raj Bajracharya of Nepal Eye Hospital.
“The warm weather, along with dust in the environment, usually results in allergy in the eyes for people, especially children,’ says the ophthalmologist.
Along with the dry hot weather, spring sees blooming of flowers which in turn also affects our eyes.
As Dr Piyush Raj Panday, also from Nepal Eye Hospital, says, “The pollen grains in the air can cause allergies very easily. It starts with itching, which most people don’t control, and thus the allergy spreads even more.”
With such various molecules in the air, the best idea would be to wear glasses, whether they be vision-correcting one or sun-glasses. However, this also has a certain risk that can affect the eyes even more.
Some of the glasses available in the market have low-quality lenses which might protect against physical particles. However, they are useless against harmful rays from the sun which are more prominent in spring and summer.
“There are Ultra-Violet rays in the environment which might cause a growth of tissues in the eyes,” reiterates Dr Bajracharya. “If this growth covers the pupil, it will permanently affect the vision of the person, even after operation,” he adds.
The UV rays from the sun are usually subdued if the eyeball is not directly exposed to the sun’s rays. In extreme cases, however, UV rays can also bounce off snow, sand or water and have an impact on the eyes.
Acute effects of UV radiation exposure include inflammatory reactions like photokeratitis and photoconjunctivitis, which can be compared to sunburn on highly sensitive tissues of the eyeball. Both are very painful though are considered reversible.
Low intensity of UV rays are also emitted from fluorescent lamps, TV and computer monitors. UV rays are also considered, by the World Health Organization (WHO), to be a major risk factor in cataract development, which is the leading cause of blindness in the world.
“People, whose eyes get affected by UV rays easily, must take precaution by wearing UV protective glasses in the sun. Otherwise, growth of tissue is inevitable,” Dr Bajracharya advises.
There is also the problem of dry eyes which has steadily been rising through the years. When an eye is dry, the eyeball becomes more sensitive and is vulnerable to allergy.
As Dr Panday points out, “Dry eyes happen throughout the year. However, during spring, with the increase in pollen and dust particles, infections on dry eyes can occur more easily.”
