To make your glasses more effective, you can ask help from your opticians who can offer you the following add-ons:
Anti-scratch Coating: All the plastic glasses needs adequate anti-scratch coating for adequate lens durability. Plastic classes are prone to scratches than glass lenses that’s why all plastic and high index plastic lenses require factory-applied anti-scratch coating which will prove helpful in the long run.
Anti-reflective Coating: An anti-reflective coating is needed for the reflection in lenses. It is helpful to remove contrast and brightness, especially at night. It is also used to make the glass invisible without irritating glints and reflections in photographs. It is a must for high-index lenses to escape from significant glare. He must use a screen or any device for longer he/she must use an anti-reflective coating.
UV-blocking treatment: Exposure to the sun and ultraviolet radiation can be harmful to the eyes mainly those who have age-related eye problems, cataracts and macular degeneration are also included in this. All high index plastic lenses have 100% UV protection build-in but if others needed UV protection are inbuilt.
Photochromic treatment: This act like sunglasses when you are outdoor and the lens automatically darkens in response to the sun’s UV days and high energy visible lights and then when you come to Indore it becomes clear like normal glasses. In case you stay mostly outdoors this present is the best option.
Reading Glasses
Many people choose separate glasses in reading time. That become helpful in close view. But changing glasses always become cumbersome. In this situation, one can go for bifocal lenses which is an easy and economical option.
Bifocal lenses are separated by a visible line. It can show you from a distance and near. The difference is also noticeable. It has a part separated for reading only. It doesn’t correct intermediate distances which are needed in computer use.
If you want the benefit of bifocal lenses you can opt for progressive lenses which is a bit expensive. If you want a smoother blend between distance and near vision you can go for this one. Because of its multifocal lens is it has no visible nine in it.
Contact Lenses
In case you don’t want fancy faces you can choose contact lenses even sometimes your doctor can recommend you to choose that. Here is a small guideline to aid you in choosing contact lenses following the guidelines of your ophthalmologists.
There are two types of contact lenses available. They are categorised by the material it is made of and the permeability to oxygen, one is hard and the other one is soft.
Hard lenses allow the free flow of oxygen through lenses to the cornea. Hard lenses are rigid gas permeable. In case of high astigmatic error, one must use RGP lenses. Mostly allergy-prone patients are prescribed hard lenses.
Soft lenses are comfortable to carry and it comes in invariants.
Daily-wear lenses are economical and reusable as well as disposable. It cannot be worn for more than 8 hours or at night.
Disposable lenses are expensive but easy to use. They are replaced after a certain time. Doctors recommend disposable lenses to allergy-prone patients and who have protein deposits on their contact lenses.
Extended-wear lenses can be worn overnight but you have to remove them at least once a week through cleaning and disinfection.
Coloured contact lenses are used for changing eye colour. They are mostly used for cosmetic reasons even in people who do not need any glasses. Like all other contact lenses, they also have the chance of eye damage like dry eyes, infection and sometimes vision losses.
Toric soft contact lenses are very expensive. It has the power to correct astigmatism but is not efficient as RPG lenses.
Bifocal or multifocal contact lenses user does not need different glasses for reading. They are available in both soft and RPG variants. With the help of presbyopia, it can correct nearsightedness farsightedness and astigmatism also.
In case you do not want the hassle of spectacles or problems related to contact lenses, you can always discuss the various options available for surgeries for the removal of glasses with your treating eye doctor.
Last but not least if you are not comfortable with glasses or any other Lenses, you can go for surgery, suggested by your doctor for the removal of extra hassle.
