receiving the filtered display section from the display cache if the filtered display section is determined to be stored within the display cache; and

displaying the filtered display section within the display area.

8. The method of claim 7 , further comprising filtering the display section to create a filtered display section if the filtered display section is determined to not be stored within the display cache.

9. The method of claim 8 , further comprising storing the created filtered display section in the display cache.

10. The method of claim 9 , further comprising:

determining a fingerprint of the filtered display section; and

storing the fingerprint in the display cache.

11. The method of claim 7 , wherein determining whether a filtered display section is stored within the display cache comprises determining whether a fingerprint of the display section is associated with the filtered display section.

12. A non-transitory computer-readable storage medium having computer-executable instructions embodied thereon, wherein, when executed by a processor, the computer-executable instructions cause the processor to:

receive a fingerprint of a display section, wherein the display section includes data to be displayed in a portion of a display area;

receive a prescription of a colorblind user;

determine, based on the fingerprint, that data corresponding to the display section is stored within the display cache;

based on determining that data corresponding to the display section is stored within the display cache, determine whether the display section corresponds to a filtered display section that compensates for colorblindness of the colorblind user viewing the display area based on the prescription of the colorblind user;

when it is determined that the display section corresponds to a filtered display section, determine whether the filtered display section is stored within the display cache, when it is determined that the filtered display section is stored within the display cache, retrieve the filtered display section from the display cache;

determine whether a filtered display section is stored within the display cache by determining whether a fingerprint of the display section is associated with a fingerprint of the filtered display section;

and

cause the filtered display section to be displayed within the display area.

13. The non-transitory computer-readable storage medium of claim 12 , wherein the computer-executable instructions further cause the processor to filter the display section to create a filtered display section if the filtered display section is determined to not be stored within the display cache.

14. The non-transitory computer-readable storage medium of claim 13 , wherein the computer-executable instructions further cause the processor to store the created filtered display section in the display cache.

15. The non-transitory computer-readable storage medium of claim 14 , wherein the computer-executable instructions further cause the processor to:

determine a fingerprint of the filtered display section; and

store the fingerprint in the display cache.

16. The non-transitory computer-readable storage medium of claim 12 , wherein the computer-executable instructions further cause the processor to determine whether a filtered display section is stored within the display cache by determining whether a fingerprint of the display section is associated with the filtered display section.

17. A method of simulating a prescription lens within a computing device, the method comprising:

receiving, by a processor, prescription data of a colorblind user, wherein the prescription data includes data representative of at least one color to be changed within a display area to compensate for colorblindness of the colorblind user viewing the display area;

determining that data corresponding to the display area is stored within a display cache;

determining that the display area is subject to the prescription data;

based on determining that data corresponding to the display area is stored within the display cache and is subject to the prescription data, determining that data corresponding to the display area being filtered using the prescription data is not stored within the display cache;

based on the determination that data corresponding to the filtered display area is not stored within the display cache, selecting, by the processor, a filter that compensates for colorblindness of the colorblind user viewing the display area based on the prescription data;
