Prescription Glasses: Why they are here to stay
We live in an age where people have less stigma towards glasses wearers as physically weak, highly intelligent beings. In fact, glasses are becoming so popular that 4 billion people worldwide choose to wear them and the global eyewear market has been valued at USD 102.66 billion in 2015.
Apart from being an aid to see better, glasses have also become fashion statements and more fashion houses have decided to include designer frames in their lines. With the rising acceptance and popularity of “geeks” and “nerds”, spectacle wearers are now often looked at as people who are professional and secure people who can combine smart and sexy at the same time.
Prescription glasses are not necessarily for those who exclusively have vision problems. The increasing use of computers and smartphones have led to an increase of myopia due to genetic and environmental factors. Which is why prescriptions for UV protection glasses have also seen an increase in popularity in the recent years.
While glasses are popular and can be obtained anywhere, it is still better to get regular eye exams and have a specific type of glasses prescribed. There are special grades and coatings that are available that make your glasses help you take care of your eyesight.
One thing to remember is that ophthalmologists and optometrists are not the same. The former are able to perform eye surgeries and procedures and can do a more thorough eye exam for more complex complaints. The latter can do routine eye exams and prescriptions only.
Astigmatism is another condition caused by an irregular curvature of the lens which may cause distortion of images passed into the brain. While it may seem harmless, astigmatism can worsen if not given the right correction and may cause discomfort in going about normal daily activities.
There are different kinds of eyeglasses available:
- Aspheric : conventional lenses that has the same curve across its entire surface
- Bifocal and Trifocal: combine vision correction for near and far sightedness
- High Index: Thinner, lighter lenses
- Photochromic: clear lenses indoors that darken automatically when outdoors
- Progressive: lens with a smooth transition between parts with different focal lengths to correct vision at all distances.
While there are more options available that make vision correction easier for movement, prescription glasses continue to be the safest and cheaper option in giving people a faster relief to vision problems.
